Answer:
Crossing over
Explanation:
Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.
Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.
People who have leukemia, a cancer that affects white blood cells, are often given Cytrabine. This drug inhibits the synthesis of DNA.
S-phase of cell cycle is most affected by Cytrabine because cytrabine interfers with synthesis of DNA and we know that in S-phase of cell cycle synthesis of DNA takes place.
