I believe the correct answer from the choices listed above is the first option. <span>The biodiversity and distribution of penguin species in the Antarctic Peninsula are changing as sea ice disappears. This is caused by the climate change which causes glaciers to melt down rising the sea levels. Hope this answers the question. Have a nice day.</span>
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.
I know that 3 is affected
Answer:
antigens
Explanation:
Specific immune responses are triggered by antigens. Antigens are usually found on the surface of pathogens and are unique to that particular pathogen. The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies.
