Repair Systems
DNA Polymerase is best described how?
A Backspace to fix the ends of the DNA
What are transposable elements?
Transposable elements are "jumping genes" that can move within and between chromosomes. They insert themselves in various locations and are found in all organisms.
Mismatch Repair occurs how?
Mismatches are detected, cut, and removed. The correct nucleotide is then inserted by DNA polymerase.
Internal sequence, terminal sequence, and the inverted terminal sequence
SOS Repair system is a last resort system that operates by producing multiple forms of what?
Over 20 repair genes to attempt to fix the damage.
Who won the Nobel Prize for discovering transposable elements within corn?
Barbara McClinton
What is Photoactivation repair?
A photon is absorbed to be used for repair to fix UV damage.
What is required for Dissociation genes to move?
Activator genes
What is Base and Nucleotide Repair? How does it occur? What enzymes are involved?
Base and Nucleotide repair is the excising of the nitrogenous base or nucleotide using DNA glycosylase (Base repair to take out nitrogenous base) or nuclease (Nucleotide/base Repair to nick DNA). Polymerase and ligase fills in the gap and a new base or nucleotide is created using the other strand as a template.
What is the class of DNA element in Drosophila transcribed into "copious amounts of RNA?
