Questions and Answers

What is the function of the enhancer in liver cells with active albumin expression?

It facilitates the combination of a protein to specific DNA sites (correct)
It promotes the development of mutant genes in liver cells
It activates the production of recombinase in liver cells
It prevents recombination in liver cells

What is the significance of the technique mentioned in the text in mutating a specific gene?

It enables mutation in a specific subset of cells while leaving the gene unaltered elsewhere (correct)
It allows for random mutations in any gene of interest
It ensures a complete and embryonically lethal mutation in any specific gene
It causes mutations in genes only during the early stages of development

What can be inferred about the expression of albumin and recombinase in cells with no albumin expression?

Recombinase is produced but albumin is not expressed
Albumin is expressed but recombinase is not produced
Albumin expression leads to an increase in recombinase production
Both albumin and recombinase are not expressed (correct)
