Mitosis Review Question Set These are the basic questions that you should be able to answer in order to synthesis answers for higher level question. Suggestion for Review: Print. Fold paper in half, quiz yourself. Vocabulary: Mitosis, Cell Cycle, DNA, Interphase, Prohase, Metaphase, Anaphase, Telophase, Cytokinesis, Chromation, Chromasome, Centromere, Sister Chromatid, Nuclear Envelope, Centriole, Spindle Fiber, Cell Plate, Asexual Reproduction, Eukaryote, Nucleus, Parent Cell, Daughter Cell, Question What do all cells have in common? What is the difference between Prokaryotic and Eukaryotic cells? How do Prokaryotic cells reproduce? Why do cells divide? Answer: Cell membrane, genetic material Eukaryotic: nucleus, membrane bound organelles, can be multicellular organisms Binary Fission What is the cell cycle? What are the three stages of the cell cycle? What is the longest part of the cell cycle? What happens during Interphase? What are the phases of Mitosis in order? What three things happen during Prophase? What to the spindle fibers do? What happens to the chromosomes during Metaphase? What happens during Anaphase? What happens to the nuclear envelope during Telophase? What is the phase of the cell cycle when the cytoplasm finally divides in two? What are the resulting cells called after cell division? How is a chromosome different from DNA. What structure helps the DNA coil? Describe the structure of the chromosome. Why are there check points in the cell cycle? To grow and develop, reproduce (as a species) , repair tissue The cycle from parent cell to daughter cells Interphase, Mitosis, Cytokinesis Interphase DNA replication and holding pattern Prophase, Metaphase, Anaphase, Telophase Centrioles move, Nuc. Env. Dissolves, DNA condenses Pull the sister chromatids apart Chromosomes align in the middle Sister Chromatids are pulled apart It reforms Cytokinesis Daughter cells Chromosomes are DNA coiled with histone proteins Histones Two Super coiled DNA strands wound around histones. Sister chromatids are attached at a centromere To stop unwanted or messed up cellular division. (cancer) Print cut and sort. Interphase Prophase Metaphase Anaphase Telophase DNA is replicated is the nucleus. The longest phase of the cell cycle. The centrioles move to opposite ends of the cell. DNA condenses into chromosomes, nuclear envelope dissolves. The chromosomes align in the middle of the cell. Spindle fibers connect the centrioles and the sister chromatids. The spindle fibers pull sister chromatids to opposite ends of the cell. The nuclear envelope starts to reform. The cytoplasm pinches inward and a cell plate appears between the developing daughter cells. Cytokinesis The cytoplasm pinches off. Chromosomes unwind and daughter cells are formed. DNA Structure Question Set Vocabulary: DNA, deoxyribonucleic acid, phosphate, sugar, carbohydrate, nucleic acid, hydrogen bond, ester bond, nitrogenous base, adenine, cytosine, thymine, guanine, backbone, double helix, Purine, Pyrimidine, Base pairing, complimentary, nucleotide, polymer, monomer Question: Who is credited with the discovery of the shape of DNA? What two things did Francis Crick say that DNA could do? What type of biomolecule is DNA? Nucleic Acids are made of what type of monomer? Nucleotides are composed of three parts. What are they? How many types of Nitrogenous bases are there in DNA? What are the 4 nitrogenous bases? Which two have double rings? What are the double ringed nitrogenous bases called? What are the single ringed bases called? What is the “backbone” of DNA made out of? What is the scientific name for the shape of DNA? What is “Base Pairing”? Adenine always pairs with…? Cytosine always pairs with….? Why is it important that “Base Pairing” occurs? What type of bond occurs between the nitrogenous bases? What type of bond occurs between the phosphate and sugar groups? What does 5’ 3’ mean? Answer: James Watson and Francis Crick in 1962 It can replicate itself and it contains the information for all cellular processes A nucleic acid Nucleotides Phosphate group, a sugar, and a nitrogen base 4 Adenine, Cytosine, Guanine, thymine Adenine and Guanine Purines Pyrimidines Phosphate and sugar groups repeating Deoxyribonucleic acid The process by which nitrogenous base only combine with a select other nitrogenous base Thymine Guanine It means the you can always reconstruct the opposite strand using the single strand Hydrogen bonds Ester bonds DNA has directionality. Each strand is assembles in the opposite direction. The phosphate is 5’ , the sugar is the 3’ end. DNA Replication Question Set Vocabulary: nucleic acid, hydrogen bond, nitrogenous base, adenine, cytosine, thymine, guanine, backbone, double helix, Base pairing, complimentary, helicase, DNA polymerase, Ligase, lagging strand, okazaki fragments, replication fork, nucleotide Question: What is the semi-conservative model for DNA replication? What is an “origin of replication”? How does replication know where to start? Can a Eukaryote have more than one “origin of replication”? Why is it an advantage to have many Replication bubbles? What is the name for the Y-shaped region at the end of the bubble where the Helix is being unzipped? What type of protein enzyme is responsible for “unzipping” the helix? What enzyme starts the actual synthesis of the new DNA? What does DNA polymerase do? Which end are nucleotides added to? 3’ replication occurs 5’ to 3’ What is the difference between Leading strand and lagging strand? What are Okazaki fragments? What rejoins the Okazaki fragments? Where does DNA replication occur? Answer: New strands are one old one new. Where replication starts. Short stretches of nucleotide sequences. can have 100’s Faster process The replication fork helicase DNA polymerase It binds nucleotides to create a complimentary strand of new DNA replication occurs 5’ to 3’ Leading strand lead the fork division and occur continuously. Lagging strand follow behind and are discontinuous. The lagging strand segments. Ligase In the nucleus Transcription Question Set Vocabulary: DNA, RNA (ribonucleic acid), nitrogenous base, adenine, cytosine, thymine, guanine, uracil, single stranded, backbone, double helix, Base pairing, complimentary, RNA polymerase Question: What does it mean to transcribe? What enzyme unzips DNA during transcription? What different nucleotide do they use? How does RNA polymerase know where to begin? Where does transcription occur? What is the central Dogma of Biology? What type of RNA is generated during transcription? How does the mRNA compare to the DNA? Why is only a small portion of DNA transcribed? Why is mRNA needed? What are the two DNA strands called during transcription? Where does the mRNA go after it is constructed? What is a promoter? What is a terminator or termination region? Answer: To create another version RNA polymerase Uracil Specific Sequences In the nucleus DNA is transcribed into RNA, RNA is translated into Proteins mRNA (messenger RNA) It is a compliment. (but, thymine is replaced with uracil) Only a small piece contains the specific code needed at that time. DNA does not leave the nucleus. mRNA delivers the info from DNA to the ribosomes in the cytoplasm The strand being used is called the or “template strand” or “antisense strand”. The other strand is the “non-coding strand” Into the cytoplasm to a ribosome A region of DNA that promotes the bonding of RNA polymerase to start transcription. Where RNA polymerase is signaled to stop transcribing. Translation Question Set Vocabulary: DNA, RNA, nitrogenous base, adenine, cytosine, thymine, guanine, uracil, Base pairing, complimentary, mRNA, tRNA, rRNA, Anti-codon, codon, amino acid, peptide bond, polypeptide, polymer, monomer, protein, synthesis, Question What is translation? Where is the code for the amino acids coming from? How does the mRNA code compare to the DNA code? What type of RNA is composed much of the structure of a ribosome? What is the function of tRNA? How does the tRNA code compare to that of the mRNA? How does the tRNA code compare to that of the original DNA? What monomer or building block does tRNA contribute to the translation process? How do tRNA molecules relate to amino acids? How many nitrogenous bases long is a codon? How many amino acids are used by the human body? Answer: The process by which RNA codes for Amino acids to make polypeptides (proteins) DNA in the nucleus, carried by mRNA It is opposite or complimentary. Ex: DNA=ATG mRNA= UAC rRNA Each tRNA delivers a specific amino acid to the ribosome to be added to the growing polypeptide chain. The tRNA carries a anti-codon or opposite codon to the mRNA message tRNA is a RNA copy of the coding strand of DNA. EX: coding DNA=ATG template DNA= TAC mRNA=AUG (codon) tRNA=UAC (anti-codon) Amino acids They are specific to one type of amino acid Three 20
