Question

42. which of the following is NOT a normal property of eukaryotic mRNAs ?

a. most have a significant untranslated region that doesnot direct assemble of amino acids.

b. all of the answers describe normal properties of eukaryotic mRNa's

c. they are found in the cytoplasm

d. they are processed from pre mRNAs to mRNAs in the nucleus and are exported through the nuclear pore complex.

e. they are often being translated by more than one ribosome ar a time in a structure known as a polyribosome or polysome

Answer 1

b) all of the answers describe are normal properties of eukaryotic mRNA.

Explanation- Eukaryotic mRNA has untranslated regions which help in translation control, export and stability of mRNA. They are found in cytoplasm and get develop from pre mRNA to mRNA in nucleus where modification are done to protect mRNA in cytoplasm. In eukaryotic mRNA polysomes are found which results from more than one ribosomes working on single mRNA.
