The two strands of DNA are held together by bonds, but can be denatured by and The nucleotides are linked together at backbone by. bonds which are much stronger and require ATP driven enzyme to break and create them. Replication/elongation of daughter strands occurs in the (opposite) to the parent/template strand. During TXN, the template is read in the During TLN, the polypeptide is synthesized in the orientation and is orientation. orientation. Describe how telomeres can be added. Why do they need to be added Describe replication licensing. Describe synthesis mechanism of leading (continuous) vs lagging strands (discontinuous). How are they similar and different. What are the players involved. What do the following do? Helicase Gyrase Ligase Topoisomerase primase DNA Polymerase Prokaryotic vs eukaryotic I, III, 8, ɛ, Y, n RNA Polymerase I, II, III and RNAP Prokaryotic vs eukaryotic DNA can be damaged in a number of ways. For example, depurination is the hydrolysis of bonds groups. This type of damage can be repaired by cutting out that abasic (enzyme), filling in the gap with DNA Polymerase (euks), and then ligating the new nucleotide to the backbone with between and nucleotide from the backbone with _(bact), or (enzyme), which forms a bond. Which of the following depends on complementary base pairing? a. DNA replication b. Transcription c. Translation d. Both a and b e. All of the above RNA molecules that act as catalysts are called a. ribozymes. b. glycosidic linkages. c. chaperonins. d. disulfide bridges. CS Scanned with CamScanner
