About 98 of the E coli genome codes for proteins yet mRNA t

About 98 % of the E. coli genome codes for proteins, yet mRNA, the template for protein synthesis, comprises only about 2 % of the total RNA in the cell. Explain this apparent discrepancy. Drag the appropriate items to their respective bins.

is(are) unstable

do(es) not accumulate in bacteria

is(are) metabolically stable

several molecules are involved in simultaneously translating from a single informational molecule

accumulate(s) to high steady-state levels

small amount of this is used in one translation complex

mRNA Bin tRNA&rRNA bin

Solution

mRNA Bin

tRNA&rRNA bin

is(are) unstable; because of single trans acting strands.

is(are) metabolically stable; because of they are constituent material for amino acids carrier and ribosome and also having various hairpin loops.

do(es) not accumulate in bacteria; because of complete degradation in mono nucleotides.

accumulate(s) to high steady-state levels, under lipase or other enzymes activity they get accumulate

small amount of this is used in one translation complex; mRNA uses in small amount

several molecules are involved in simultaneously translating from a single informational molecule; different tRNAs are used for different amino acids and rRNA also has various RNA subunits.

The mRNAs are required to make proteins. They are easy to translate whenever required. On the other hand tRNAs and rRNAs are required to make amino acids carrier and ribosome respectively. Cells need to have many tRNAs because of their individual differences. Lot of Ribosomes are required to present in the cell for the readily availability of protein production place.
