A DNA is a
helix molecule composed of complementary strands of
deoxyribonucleotides units while RNA is single stranded. The complementary base
pairs of the DNA are held by
sugars, phosphate groups, and nitrogenous
bases and its shape is a double helix. The complementary structure the two strands
of DNA allow each strand to serve as a template. During

DNA to replicate itself with accuracy. The sequence of nucleotides in DNA directs the

There are three major types of RNA
that help build proteins: mRNA, rRNA, and tRNA. The

information in DNA to the ribosomes found in the cytoplasm. The process of
converting the information in messenger RNA into a sequence of amino acids that
make a protein is known as
The role of

the base sequence of DNA and it may affect only one gene, or they may affect whole
chromosomes.​
