Back Slide A2 Meiosis produces these types of cells What are four genetically different haploid cells? Back Slide A3 This is the number of chromosomes in a gamete What is N? Back Slide A4 When homologous chromosomes line up and exchange portions of their “arms” it is called this What is crossing-over? Back Slide A5 Homologous chromosomes are separated during this phase of Meiosis. What is Anaphase I? Back Slide B1 DNA is composed of these three molecules. What is Deoxyribose, a phosphate group, and a base? Back Slide B2 This molecule “unzips” the DNA molecule in preparation for DNA Replication. What is DNA Polymerase? Back Slide B3 In order for DNA to “unzip” these two events must occur. What are the breaking of hydrogen bonds between the base pairs and the unwinding of the DNA strands? Back Slide B4 DNA replication results in two strands, each with these. What is one original strand and one new strand? Back Slide B5 If this DNA strand was the template for DNA replication, the resulting DNA strand would be . . . ATCGCGTA TAGCGCAT Back Slide C1 The process in which an RNA strand is made based off a DNA template What is Transcription? Back Slide C2 The molecule that directs mRNA synthesis What is RNA Polymerase? Back Slide C3 This is where transcription takes place. What is inside the nucleus of a cell? Back Slide C4 These are the three components of an RNA nucleotide. What are Ribose, a phosphate group, and a base? Back Slide C5 These are the four main differences between RNA and DNA. What are single vs. double strands, Uracil vs. Thymine, Deoxyribose vs. Ribose, and the ability to leave the nucleus vs. not leaving the nucleus? Back Slide D1 This process uses information from mRNA to make proteins. What is translation? Back Slide D2 These contain information for making proteins. What are genes? Back Slide D3 These types of RNA are involved in protein synthesis. What are mRNA, tRNA, and rRNA? Back Slide D4 This RNA molecule carries amino acids to the ribosomes. What is tRNA? Back Slide D5 This causes translation to stop. What is a stop codon? Back Final Round This codes for one amino acid. What is a codon? Back
