Jason does not have cystic fibrosis and it is his phenotype (physical expression of the gene) for the trait.

the greenhouse gas, methane, is released by cattle as a product of their metabolism. what effect would an increase in cattle ranching be expected to have on climate? increased temperatures.
Answer:
The answer is given below.
Explanation:
A tiny difference in a distant enhancer make a blond through DNA Looping.
DNA Looping can bring the enhancer bound by an activator physically closer to the promoter even if the enhancer is located far away along the DNA molecule.
DNA Looping.
When a protein or a set of complex proteins binds to 2 different sites of DNA simultaneously while looping out the interfering DNA.
Important of DNA Looping
- It regulates metabolism of DNA
- it is involved in transcriptional initiation of prokaryotic operons.
