Is that a test your taking?
Because its the first step ti a gene expression.
Transcription factors are proteins that regulate the transcription of genes—that is, their copying into RNA, on the way to making a protein. The human body contains many transcription factors.
Answer:
This may be the case because of the placements of the spread. While one is more cluttered, the other is a bit more spread apart. Meaning that the GeoChart on the right must have more cases, exactly because of their population.
a point mutation only mutates and changes that particular spot in the DNA strand while a frameshift changes the whole strand by moving the bases either one forward or backward
So, since the trait is eye color, let's use E to represent the dominant allele (brown) and e to represent the recessive allele (blue).
I've attached a Punnett square, but let me real quick explain how I set it up. We know that both parents are heterozygous, which means that they have one of each allele. So that gave us the two sides. Then I filled in the boxes (I assume you've leaned how to do this, if message me and I can explain it).
Looking at the results we can see that 1/4 of the offspring are EE, 1/2 are Ee, and 1/4 are ee. Since the blue allele (e) is recessive, it'll only be expressed if no dominant brown alleles (E) are present. Therefore, only the ee genotype will exhibit blue eyes. So, 1/4 or 25% of the offspring will have blue eyes.
Hope that helps! If you need clarification or anything feel free to message me :)
