Answer:
The genetic material of most of the organism is Dexoxy-ribonucleic acid OR DNA which are formed of the monomer unit called nucleotide.
Each nucleotide is composed of a 5-C deoxyribose sugar, a phosphate group and 4 types of nitrogenous bases mainly adenine, cytosine, guanine and thymine.
It is the sequence of these nitrogenous bases which determine the fate of a cell as these nitrogenous bases are read by the ribosome in the form of triplets called codons where each codon codes for specific amino acids. These amino acids bind to each other via peptide bonds to form proteins.
Thus, these nitrogenous bases control the important property of the cell.
Am amniotic egg is first developed in the reptiles.
The membrane and shell make a protective membrane that can provide a safe environment for the cells to divide, and embryo to develop. Animals having an amniotic shell are called as amniotes. The other body parts develop later on.
