"The differences in pre-mRNA splicing that results in an altered pattern of exon inclusion" is most likely to have contributed to this phenomenon.
<u>Option: C</u>
<u>Explanation:</u>
The expression of the eukaryotic gene requires several stages and can be regulated by several of them. Different genes are controlled at different locations and it is not unusual for a gene to be controlled at multiple steps, especially a significant or powerful one.
- In accessibility of Chromatin the chromatin structure includes DNA and can be regulated by its assembling proteins. More free or 'relaxed' chromatin allows a gene more transcriptible.
- For many genes transcription is a key regulatory point. Its factor protein sets bind to unique DNA sequences within or near to a gene and encourage or suppress its transcription into an RNA.
- It is possible to control the splicing, capping, and attaching a poly-A tail to an RNA molecule, and thus exit the nucleus. Specific mRNAs might be produced by alternative splicing from the same pre-mRNA.
60 million years is the answer.
B. They express the recessive trait
Answer:
You eat a hamburger and breath oxygen
Oxygen goes immediately from your lungs to blood vessels to cells.
Food molecules in the hamburger are broken down into glucose in the digestive system.
Oxygen and glucose combine to form carbon dioxide, water, and ATP.
Energy is used by cells in your body to function and grow; you exhale carbon dioxide.
