Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids. Ribonucleic acid is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA and deoxyribonucleic acid are nucleic acids. #GeneticsFieldOfStudy #MolecularGeneticsFieldOfStudy #DNA #mRNA #polypeptide #peptide #ABOBloodType #BloodGroup #AlleleFrequency #GenotypeFrequency #ABOBloodTypes #ABOBloodGroups #RhBloodGroups #blood #classification #antibodies #transfusion #incompatibility #rhesus #bloodGroupsAndBloodTypes #bloodGroupsExplained #bloodGroupsAndTransfusions #bloodGroupsVideo #aboBloodTypesExplained #aboBloodGroupSystem #aboBloodTyping #bloodTypesAndRhFactor
