Question

In what way(s) can mRNAs be processed? In what way(s) can mRNAs be processed? By adding caps and tails to the ends of the mRNAs By removing the introns (the noncoding regions) of the mRNAs By splicing the exons (the coding regions) of the mRNAs in different ways All of the above are ways in which mRNAs can be processed

Answer 1

Answer:

All of the above are ways in which mRNA can be processed.

Explanation:

DNA is transcribed into pre-mRNA which is further processed into mature mRNA. mRNA be processed by various ways: as at the 5' end of RNA, addition of capping occurs,  and at the 3' end, there is addition of large number of adenosine ( approx 200), known as polyadenylation.

RNA splicing is the process of removal of introns and of addition of exons, through which only coding sequences (exons) remain in the mature mRNA and non coding regions(intron) are removed.

Alternative splicing may produced various type of mRNA from a single type of pre- mRNA.
