Nucleic acids are the macromolecules in the living cells. When these nucleic acids combine with proteins, they form nucleoproteins. The protein components are protamine and histones. Nucleic acids are polymers of nucleotides which are linked by phosphor-di-ester bond and are […]
Structure of DNA DNA and RNA are nucleic acids found in plant cells. These nucleic acids are constructed from building blocks called nucleotides. A nucleotide is made of a nitrogen-containing base, a 5-carbon pentose sugar, and phosphate group. A […]
Chromosomes The nucleus of all the body cells contain an identical copy of the individual’s genetic material. RBCs and sex cells(gametes) are the only two exception which does not contains the identical copy. In a cell, chromatin (genetic material) is […]
