Question
Chapter 20, Problem 7CONQ
Summary Introduction
To review:
The production and occurrence of recombinant and non-recombinant chromosomes through resolution step of the Holliday model of homologous recombination.
Introduction:
The Holliday model was proposed by the Robin Holliday in 1964 for the formation of heteroduplex and the gene conversion at the time of recombination. This model has a key role in the homologous type of recombination.

- What is recombination? Mention its applications with reference to genetic engineering.arrow_forwardTwo pathways, homologous recombination and nonhomologous end joining (NHEJ), can repair double-strandbreaks in DNA. If homologous recombination is an errorfree pathway whereas NHEJ is not always error free, whyis NHEJ used most of the time in eukaryotes?arrow_forwardIn each of the illustrations below, a segment of a chromosome has two copies of a transposable element. In panel a, they are oriented in the same direction, whereas in panel b they are in opposite directions. A double strand break occurs in element A and is repaired by homologous recombination using element B as a repair template. For each case, what will the chromosome look like after homologous recombination occurs? Choose one of the five options below, 1-5.arrow_forward
