Answer:
option A
Explanation:
In carrying out these experimental procedure, the same restriction enzyme that is used to cut out the gene of interest should also be the same used for the cutting of the plasmid to generate sticky ends. Then the desired gene is inserted into the cut plasmid then treatment with DNA ligase. Purified DNA ligase is utilized in gene cloning to join/ligate DNA molecules together forming a recombinant DNA. Thus, step 3 should be carried out after step 4.
The cause of mutations in gene expressions are the changes of gene instructions that causes your protein to malfunction. The effect of mutations are the genes not being able to function properly and send the wrong codes/info to your cells.
If the chromosome is an X shape the two rods that make it up are chromatids and the center that holds them together is the centromere

Answer:
What is cell differentiation regulated by?
Differentiation. Cellular differentiation is a complex process that involves the coordinated regulation of genes by a multitude of cellular pathways. Differentiation is controlled a number of DNA binding proteins that are aberrantly expressed in PDAC.
