Answer:
genomic imprinting
Explanation:
Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.
Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.
Answer:
Answer is A. B-hemoglobin mRNA is translated more efficiently than is a-hemoglobin mRNA.
Explanation:
The introduction of electric charge into a gel or fluid, causing or resulting in the movement of the charged particles in the gel or fluid, is referred to as the electrophoresis. It can also be explained as a separation method or technique which is based on the movement of particles or ions in an electric field.
The electrophoresis is used in separating DNA fragments , RNA or protein, based on their size and charge.
That answer would be no. because not all of them are the same.
Answer:
The correct answer is - yes, variation can be advantageous.
Explanation:
The population of the lima beans that are able to adapt to changes and include these variations in their population will lead individuals are able to survive and reproduce to increase their numbers in changing environments. The igher the variability in the population is, the higher the chances of the to be advantageous for their survival and increase their population.
Thus, the correct answer is - yes.
23. The answer would be the third option.
24. The answer would be the second option.
