Answer:
1. Occupy different niches
Answer: The claim that gene regulation results in differential gene expression and influences cellular products (albumin or crystalline) is best supported by t<u>he specific transcription factors made in a cell.</u>
Explanation:
Genes store deoxyribonucleic acid or DNA that makes up the genome. The genetic information within genes is expressed through a process called transcription followed by translation.
During this, the genotype of the organism is changed into its phenotype or physical characteristics genes are controlled or regulated through certain molecular mechanisms These essentially determine transcription and translation and whether gene products is active or in active genes are turned on when they are able to transcribe the genome.
gene expression may be regulated
via
- modulation before or after the transcription process
- modulating translation
- modulation after translation
A control for the transcription process is called a transcription factor. These are DNA sequence specific proteins that are capable of activating or suppressing transcription at certain sites. In different cell types, different combinations of transcription factors contribute to gene expression.
The correct option is B.
Gene flow refers to the movement of genes from one population to another population. The movement of genes in and out of a particular population usually result in significant changes in the gene frequencies of the population members that are carrying specific variant of a particular genes. Thus leading to increase in the amount of genetic variations in that population.
The correct option is C.
Both DNA and RNA are made up of four nitrogenous bases. The nitrogenous bases that are found in DNA are adenine, guanine, cytosine and thymine. The nitrogenous bases that are found in RNA are adenine, guanine, cytosine and uracil.
