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.
Answer:
One organism benefits while the other is killed, this relationship is called parasitism.
Explanation:
Parasitism is symbiotic relationship between two organisms in which one gets benefit and the other get harm. Those organisms which feed on other organisms and causes damage to them is known as parasites. There are two types of parasites. Those parasites which lives inside the host body is called endoparasite while those parasites which lives outside the body of host is known as exoparasite.
