Comparison between DNA, mRNA, rRNA and tRNA

Comparison between DNA, mRNA, rRNA and tRNA

Name	DNA	mRNA	rRNA	tRNA
Number of strands	Double stranded	Single stranded	Single stranded	Single stranded
Location	Mainly in nucleus, also in mitochondria and chloroplasts	In nucleus and cytoplasm (mainly ribosomes)	Only in ribosomes	In the cytoplasm
Functions	Acts as store of coded instructions for the synthesis of proteins required by the cell.	It is made on the DNA template. It carries coded instructions (codons) from nucleus to ribosomes for the synthesis of proteins.	Forms part of ribosome structure. Helps in locating mRNA correctly on ribosome surface.	Acts as amino acid carriers during translation (protein synthesis)
