From DNA to Protein


Knowledge of nucleic acid chemistry is essential to the understanding of dna structure

Knowledge of Nucleic Acid Chemistry Is Essential to the Understanding of DNA Structure


From dna to protein

Nucleotides are the building blocks of DNA. They consist of a nitrogenous base, a pentose sugar, and a phosphate group.


From dna to protein

A nucleoside contains the nitrogenous base and the pentose sugar. A nucleotide is a nucleoside with a phosphate group added


From dna to protein

The nitrogenous bases can be purines or pyrimidines. The purines are adenine (A) and guanine (G). The pyrimidines are cytosine (C), thymine (T), and uracil (U)


Rna contains ribose as its sugar dna contains deoxyribose

  • DNA and RNA both contain A, C, and G, but only DNA contains T and only RNA contains U.

RNA contains ribose as its sugar; DNA contains deoxyribose

  • The C-5' position is the location of the

  • phosphate group on a nucleotide.


From dna to protein

Nucleotides are linked by a phosphodiester bond between the phosphate group at the C-5' position and the OH group on the C-3' position


From dna to protein

Nucleotides are linked by a phosphodiester bond between

the phosphate group at the C-5' position and the OH

group on the C-3' position

A polynucleotide chain


From dna to protein

Antiparallel nature of the helix and the horizontal

stacking of the bases.


From dna to protein

Watson and Crick proposed DNA is a double helix in which the two strands are antiparallel and the bases are stacked on one another. The two strands are connected by A-T and G-C base pairing and there are 10 base pairs per helix turn
