What are at least two characteristics of RNA? O Single stranded
O Present at nucleus and cytoplasm
O uracil instead of thymine
O All of the above
.

Present at nucleus and cytoplasm

Characteristic feature of RNA are as follow:

Ribonucleic acid“ RNA” is another nucleic acid type. Like deoxyribonucleic acid “DNA ” it is polynucleotide but several differences are found in their structure.

In RNA the pentose sugar is ribose not deoxyribose.

RNA contain uracil in place of thymine.

RNA ,generally single stranded with partially double stranded region due to the folding at back of its single chain.

RNA sevres as genetic material in many viruses.Thrre are three major classes of cellular RNA s which function during gene expression.

These are:

Messenger RNA (mRNA)

Transfer RNA (t RNA)

Ribosomal RNA (rRNA).
