DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the ...
Each ribonucleotide base consists of a ribose sugar, a phosphate group, and a nitrogenous base. Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical ...
Each nucleotide consists of alternating sugar and phosphate sections with one of the four different bases attached to the sugar.
This is known as the base-pairing rule. A nucleotide consists of 1 phosphate, 1 sugar and 1 base. Each individual's DNA is unique. Apart from identical twins, no one shares the same sequence of bases.
