a) Phosphate group, b) Pentose sugar and c) Nitrogenous base.
Explanation:
Both RNA and DNA are the nucleic acid that are made up of nucleotides which in turn are made up of three major components – a) Phosphate group, b) Pentose sugar and c) Nitrogenous base.
A nitrogenous bases further is composed of two types of bases –
a) Purine
b) Pyrimidine
Purine - Adenine and guanine
Pyrimidine - cytosine, thymine/ uracil (in RNAs only)
These nucleotides are held together in helical arrangement by phosphodiester bonds.
Nucleic acids are molecules that are essential to, and characteristic of, life on Earth. There are two basic types of nucleic acid, DNA (oligonucleotide acid) and RNA (nucleic acid). This exercise will focus on DNA, although ways in which it differs from RNA will also be presented. DNA is found in all organisms from the smallest bacteria to humans. DNA has the same composition and structure in all organisms!DNA has two important functions.1 - it is the genetic material that is passed from one generation to the next.2 - it is the coded information that tells cells how to make proteins.
