CH 6 HW Flashcards
what pairs are at origins because they are easy to tear apart
A-T
T/F
When DNA is being replicated inside a cell, local heating occurs, allowing the two strands to separate.
F
T/F
Primase is needed to initiate DNA replication on both the leading strand and the lagging strand.
T
T/F
Telomerase is a DNA polymerase that carries its own RNA molecule to use as a template at the end of the lagging strand.
T
In addition to the repair of DNA double-strand breaks, homologous recombination is a mechanism for generating genetic diversity by swapping segments of parent chromosomes. During which process does swapping occur?
Meiosis
Nucleases
enzymes that cleave phosphodiester bonds allowing reactions to occur
Thymine dimers
Occur when adjacent Thymine are exposed to UV radiation causing covalent bonds resulting in DNA damage
