Explanation:
This may be rong, however I think this needs to happen before the mRNA can leave the nucleus. The cap helps prevent the mRNA from being destroyed by the cell itself once it leaves the nucleus.
One way is by comparative anatomy. Comparing the similar bone structure of animals gives more proof of this theory. Also, the location of some animals compared to other animals of similar species is very convenient, and supports the theory of natural selection.
Diffusion , the movement of gas molecules .
A)
Therefore:Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote).
b)
Therefore:Crossing results in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).
c)
Therefore:Crossing results in 100% (homozygous recessive).
