Homework Answers
The hnRNA is a heterogeneous RNA is the fresh product of
transcription. it contains both exon and intron.
1. Splicing - The introns are removed and exons are rejoined
together to form a mRNA.
2. Capping - The 5'end of hnRNA is free so exonuclease will
degrades the mRNA. To overcome that methyl gunosine triphosphate is
added to the 5'end of hnRNA is called 5'CAP.
3. Poly A Tail - In 3' end also the hnRNA are more probable to
cleave by exonuclease. So adenylate residues (200-300) nucleotides
added at 3'end in template independent enzyme.
After this three process the hnRNA will converted into mature mRNA.

The schematic illustrates steps in RNA processing. The DNA
strand is shown in red and yellow, and the RNA strand is shown in
green and blue. The steps in RNA processing are labeled 1-3, and
the components of the RNA transcript are labeled A-C.
Steps in RNA processing are indicated below in alphabetical
order, select the step number to put these processes in
chronological order. If the indicated step does not occur, select
'This process does not happen'.

Eukaryotic messenger RNA undergoes several processing steps after transcription before it binds to ribosomes as the template for protein synthesis. One of these steps is polyadenylation. Identify whether the statements below about polyadenylation are true or false. A polymerase adds a polyadenylate tail of about 10 nucleotides to the 3' end of the mRNA. A polymerase adds a polyadenylate tail to the mRNA while it is still in the nucleus. The polymerase forming the polyadenylate tail uses a polydT DNA...
