Mostly the DNA structure is double stranded in both eukaryotes and prokaryotes. However, in some viruses DNA is single stranded. DNA is a double stranded molecule held together by weak bonds between base pairs of nucleotides. The four nucleotides in DNA contain the bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

The History Of Dna Biology Essay. Early scientists thought that protein was the cell’s hereditary material because it was complexer than DNA. Basically proteins are made up of combination of 20 different amino acids in long chains of polypeptides that’s why scientists take them as the most complex structure and considered them the hereditary material.

The “Thread of Life”, is deoxyribonucleic acid, also known as DNA. This molecule which is the bases of life, is spiral shaped and found in the nucleus of cells. DNA has the genetic code for bodies, controls development of embryo’s, and is able to repair damage caused to itself. All DNA molecules have linked units called nucleotides.

Dna Structure And Replication Essay 351 words - 2 pages pyrimidines). In the DNA, the two strands run in opposite directions and the bases pair up so that A always pairs with T and G always pairs with C. The A-T pair has 2 hydrogen bonds and the G-C pair has 3 hydrogen bonds. The G-C interaction is therefore stronger (by about 30%) than A-T.DNA REPLICATIONDNA replicates, following the process.

There are many processes in which it is important that these shapes fit, for example DNA helicase, RNA polymerase and DNA polymerase must all have the correct shape in order for DNA strands to separate, mRNA to form and DNA to then rejoin during polypeptide synthesis. During polypeptide synthesis it is also important that Amino acyl RNA synthetase fits together with an amino acid and tRNA.
