A
Before meiosis begins, during S phase of the cell cycle, the DNA of each chromosome is replicated so that it consists of two identical sister chromatids, which remain held together through sister chromatid cohesion. This S-phase can be referred to as "premeiotic S-phase" or "meiotic S-phase".
Answer:
The below options will complete the question
Select one:
a. Gap repair synthesis
b. Mismatch repair
c. Direct repair
d. Nucleotide excision repair
Our answer is surely A.
a. Gap repair synthesis
Explanation:
Alleles of gene B differ by 6 bps and are seeming close to each other among the 1123 bp within the particular gene, favouring the gap repair synthesis.
In the gap repair synthesis, a double stranded break is formed at a homologous chromosome with a small part of the gene or the 6 bps of the recessive allele
being digested away.
Strand invasion and a D-loop formation is followed by the new region being occupied by the dominant B allele to yielding dominant B allele in both chromosomes.
The gap repair synthesis allows the 6bps to be converted to the dominant B from the recessive b when in proximity/being close together.
