DNA The Genetic Material QUESTION Is the structure and function of DNA the same in almost all organisms? Fredrick Griffith and Transformation Hershey and Chase Show That Genes Are Made of DNA Structure of DNA Nucleotides Are the Building Blocks. There are three components to a nucleotide
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.
Write the compliment for GGCTATTGGCA.
When the introns are removed, the resulting fragments are stitched together to make a protein.
