Answer:
D) results in the remodeling of chromatin that can active or inhibit gene expression
Explanation:
DNA methylation results in the tighter, euchromatin version of DNA that is harder to transcribe; its counterpart DNA acetylation results in the DNA becoming looser and easier to transcribe.
Answer:
The scientist can insert the DNA into bacteria
Explanation:
Bacteria are frequently used in biotechnology to make proteins scientists are interested in. If they know the gene and the sequence of the gene that makes the protein product, they can insert that gene into a vector that will cause the bacterial transcription and translation machinery to produce the protein.
Firsts scientists clone their DNA of interest into a vector, a circular piece of DNA that the bacteria will transcribe. The vector is then introduced to competent bacterial cells. (Competent means there are holes in the bacterial membrane that allow them to uptake the gene and vector).
Once the vector is in the bacteria, it (and the gene of interest) will be transcribed and translated as it would in the chicken liver.
Answer: the urchin population will grow very large and the kelp will diminish
Explanation:
Chromosomes from different parents determines the genetic structure of the child (from both parents) only with recessive genes ONLY becoming apparent if they are present in BOTH parents<span />
