Guanine, adenine, thymine and cytocine What is DNA often compared to? Twisted ladder What are nucleotides made out of? Sugar, phosphate group, and a nitrogenous base What did James Watson and Francis Crick discover? Double helix Who had the transformation experiment that demonstrated the change of rough bacteria into smooth? Griffith What bases bind together as a complement? Adenine to Thymine Thymine to Adenine Guanine to Cytosine Cytosine to Guanine What is responsible for unwinding and unzipping the double helix? DNA helicase What are the stages of DNA replication? Unwinding, base pairing, joining, replication What are two proteins associated in replication of DNA? DNA helicase, RNA primase, DNA polymerase, Single stranded binding protein What is the difference between eukaryotes and prokaryotes for the number of orgins for DNA replication? Eukaryotes have multiple Prokaryotes only have one What is RNA? Nucleic acid What is the code for TGA? ACU What is Beadle and Tatum’s hypothesis? One gene codes for one polypeptide What are the three types of RNA and their functions? mRNA- travel from the nucleus to the ribosome to direct synthesis of specific proteins. rRNA- proteins to form ribosome in the cytoplasm. tRNA- transports amino acids to the ribosome. ____codes for _____directs the synthesis of ________ DNA, RNA, Proteins What is a Hox gene? Crucial in development and decides which part goes where. What is deletion a cause from? Framework How many steps occurs in tryptophan synthesis? 5 T/F– An operator is a segment of DNA that acts as an on/off switch for translation. True What blocks transcription when the operon is off? A repressor What is the difference between Intron and exon? Exton stays, intron goes What is gene regulation? Ability of an organism to control which genes are transcribed in response to the environment. What is a codon? A 3 base code in DNA or RNA What is a mutagen? Substance that causes mutations What is a transcription? Process in which water evaporates from the inside to the outside
