DEOXYRIBONUCLEIC Acid (DNA) carries HEREDITARY material.DNA is a molecule that carries most of the genetic instructions used in the development, functioning and reproduction of all known living organisms and many viruses.DNA molecules are very long but are packed into compact structures called chromosomes. Each DNA molecule CONSISTS of two twisted strands of bases that form a shape called a double helix.The two strands are held together by hydrogen bonds between pairs of bases. OvulesIt contains female reproductive (eggs) gametes.RNARibonucleic Acid helps in protein synthesis and carries genetic CODE in viruses.Pollen GrainsThey are male gametophytes in angiosperms (Flowering plants)
