Question

Both liver cells and lens cells have the genes for making the proteins albumin and crystalline. However, only liver cells express the blood protein albumin and only lens cells express crystalline, the main protein in the lens of the eye. Both of these genes have enhancer
sequences associated with them.
The claim that gene regulation results in differential gene expression and influences cellular products (albumin or crystalline is best
supported by evidence in which of the following statements

Answer 1

Answer: The claim that gene regulation results in differential gene expression and influences cellular products (albumin or crystalline) is best supported by the specific transcription factors made in a cell.

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.
