The Genetic Material
Is the structure and function of DNA the same in almost all organisms?
(adenine, quanine, thymine,
One circular chromosome
5 million base pairs
Replicates in less than one hour
Humans have 46 chromosomes
6 billion base pairs
Replicated in a few hours
DNA is separated from most of the replication machinery by the nuclear envelop.
Both carry out replication very quickly and with tremendous accuracy – 1 error /billion nucleotides.
A always pairs with T and C always pairs with G. This is because of the number of bonds formed between the bases. Two hydrogen bonds form between A and T and three between C and G.

When the introns are removed, the resulting fragments are stitched together to make a protein.
