For example, both your parents could be type A, but you could still end up with type O. Around 44 per cent of people in Britain have blood group O. Type A accounts for 42 per cent and the balance is made up of less common blood types, including type B and type AB.
A polynucleotide molecule is a biopolymer composed of 13 or more nucleotide monomers covalently bonded in a chain. DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are examples of polynucleotides with distinct biological function.The prefix poly comes from the ancient Greek ÏÎ¿Î»ÏÏ (polys, many).DNA consists of two chains of polynucleotides, with each chain in the form of a helical spiral.NA (deoxyribonucleic acid) and RNA (ribonucleic acid) are examples of polynucleotides with distinct biological function.

dna structure an overview the dna structure consists of two chainlike molecules polynucleotides that twist around each other to form the classic double helix the cell s machinery forms polynucleotide chains by linking together four nucleotidesthat form the strands of the dna structure are complex molecules which consist of both a phosphate moiety and a nucleobase adenine guanine cytosine or thymine joined to a five carbon sugar deoxyribose in rna the five carbon sugar ribose replaces deoxyriboseucleotides that form the strands of the dna structure are complex molecules which consist of both a phosphate moiety and a nucleobase adenine guanine cytosine or thymine joined to a five carbon sugar deoxyribose
