Web7 apr. 2024 · Nucleotides are organic molecules that act as the building blocks of both DNA and RNA. These molecules have three components – a nitrogenous base, a pentose sugar and a phosphate group. The nitrogenous bases are of two types – purines and pyrimidines. The purines are adenine (A) and guanine (G), while the pyrimidines are cytosine (C ... WebDNA Packing: DNA is so lengthy; it requires special packaging. The DNA must be packaged properly to accommodate inside the nucleus. The cells coil their DNA across scaffolding proteins to produce chromatin, a compact structure. Chromatin is stretched further to form various structures, which finally become chromosomes.
