1. DNA and RNA are both stands of nucleotides but RNA can carry out for more functions than
DNA. How docs the structure of RNA differ from DNA? What additional activities/function can
RNA do that DNA cannot?
Solution
The structure of ribonucleic acid is single stranded in which thymine replaces uracil as
complimentary base and other adenine, guanine, cytosine are the nucleotides but
deoxyribonucleic acid is double stranded & duplex.
The additive activities can RNA performing are to undergo "translation" to code for proteins
the following are the other functions where as DNA cannot undergo translation directly to code
for proteins
Small nuclear ribonucleic acid (snRNA): It is also known as U-RNA as it contains many uridine
contents in its complex structure. This is composed of 150 nucleotides nearly to produce
spliceosomes and to act along with snRNP. This snRNA has a predominant role in splicing.
mRNA: It is produced by the transcription of DNA in the presence of RNA polymerase enzyme
and it has amino acid coding exons to code for specific proteins as per genetic code.
rRNA (ribosomal RNA): It has 50S and 30S ribosomal subunits which have aminoacyl site and
peptidyl site to carry out translation process during protein synthesis with mRNA.
tRNA (transfer RNA): It has clover leaf structure & common to all tRNA structure. It has
anticodon site to bind to the mRNA and to displace mRNA transcript from nuclear region onto
the rRNA for protein synthesis. It is considered as an adaptor molecule mainly consist of 76 to
90 ribonucleotides in length
piRNA:
Piwi-interacting RNAs (piRNA) are the small non-coding RNA molecules with 26 to 31
nucleotides that are expressed in many of the germ lines of eukaryotic animals. piRNAs interact
with piwi proteins to form RNA-protein complexes.
