Parts Of Dna Diagram. They are spirally coiled. These are long threads of dna each made up of many genes.
Dna comprises a sugar phosphate backbone and the nucleotide bases guanine cytosine adenine and thymine. The components structure of dna the components structure of dna long chain made up of units called nucleotides nucleotides are made up of three basic components 5 carbon sugar deoxyribose phosphate group nitrogenous bases purines adenine and guanine pyrimidines thymine and cytosine the components structure of dna. The diagram shows part of a molecule of dna a complete the diagram with the first letters of the appropriate complementary bases.
I the part of the molecule in box b 1 ii the dotted lines between the complementary base pairs.
Joining up lots of these gives you a part of a dna chain. They are spirally coiled. The components structure of dna the components structure of dna long chain made up of units called nucleotides nucleotides are made up of three basic components 5 carbon sugar deoxyribose phosphate group nitrogenous bases purines adenine and guanine pyrimidines thymine and cytosine the components structure of dna. Learn about the structure of dna and how to recognize all the parts in this video.
