I think the answer might be D
Answer:
In the dominant- recessive model of inheritance, the dominant allele fully suppresses the recessive allele. As a result, heterozygous individuals produced show the effect of the dominant trait in them. For the recessive trait to occur, both the alleles of the gene should be recessive in the organism.
In co- dominance model of inheritance, the dominant allele is not fully dominant over the recessive trait. As a result, heterozygous individuals show both the dominant and recessive characteristic in them. For a dominant trait to occur, both the alleles should be dominant. For a recessive trait to occur, both the alleles should be recessive.
I believe your answer should be A
Answer: e. All of the above
Explanation:
The processing of mRNA to a fully mature eukaryotic mRNA requires addition of a 5' cap (Capping) and 3' poly(A) tail ( polyadenylation) to the ends of the transcript, and removal of any intervening introns by splicing. Once processing is completed, the mRNP, which consists of mRNA and associated proteins, is ready for export from the nucleus.
