Answer:
1st Activity = Cold Front
2nd= High Pressure with a Cold Front
The answer <span>is AB and aB
<span>A man is heterozygous for sickle cell anemia: Aa
</span></span>A man is <span>homozygous dominant for familial hypercholesterolemia: BB
So, his genotype is AaBB. He will give only one allele of two for each gene.
He can have 2 different combinations in sperm cells:
- AB
- aB</span>
The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.
