Watson and crick founded the structure of DNA in 1953
The chargaff rule says that every DNA should have a one to one ratio of purines and prymindines. The amount of guanine, cytosine, adenine, and thymine should be the same
The two strands of DNA match and the mass binds with a suitable partner on the other strand.
A structure that consists of DNA and its proteins. Carries all genetic information
An image of a persons set of chromosomes
Enzymes break hydrogen bonds that hold the DNA together and the DNA separates. Primers are constructed and they are attachment points off DNA polymerase, which assembles the new DNA. The primers pairs with another stand of DNA. Polymerase attach to primers and being to replicate the DNA. DNA ligase seals any gaps and the New DNA strands are never ending. Both stands of the parent molecule are copied at the same time and as it gets longer it winds up. Two copies of DNA are made a new one and a parental one
DNA can be damaged by radiation from X-rays, UV light, and gamma rays. The DNA can be broken, bonds can be formed between opposite strands and the DNA can be changed.
