Helicase - Study guides, Class notes & Summaries

What would be the effect of a mutation in the HIV-1 reverse transcriptase gene that decreased the rate of mismatches? correct answers Any decrease in the error rate of HIVRT would result in an overall decrease in the rate of viral mutations. This would probably not be an advantage for the virus, as the relatively high error rate often helps to thwart the use of antiviral drugs. Approximately how many ATP are required by helicase for the replication of the E. coli chromosome? correct answers B...

Similarities between eukaryotic and prokaryotic cells 1) Semi-conservative 2) Bidirectional Prokaryotic cells 1) Circular DNA 2) Single origin of replication Eukaryotic cells 1) Linear DNA 2) Multiple origins of replication New strands are always synthesized from: 5' --> 3' end of each strand Template strand is read: 3' --> 5' Chain extension occurs: by adding a dNTP to free 3' end of growing polynucleotide chain DNA polymerase DNA s...

Honors Biology Semester 2 Final Exam with Complete Solutions What is the role of helicase in DNA replication? Helicase unwinds the DNA double helix by breaking hydrogen bonds between base pairs, allowing replication to begin. How does complementary base pairing ensure accuracy during DNA replication? Complementary base pairing (A with T, C with G) ensures that each new strand is an exact copy of the original template. What is a codon, and how is it related to DNA? A codon is ...
