Notes explaining the structure of DNA, replication process of DNA, how mutations work in DNA, and the Polymerase chain reaction process

-DNA is a polymer of nucleotides -Each nucleotide consists of a nitrogenous base, a sugar, and a phosphate group -The sugar in DNA is a pentose sugar called deoxyribose -The different kinds of bases are adenine, thymine, guanine, and cytosine -In DNA, there is a 1:1 ratio of nucleotide bases: number of adenine = number of thymine and number of guanine = number of cytosine -DNA consists of 2 strands in a shape called a double helix <…showed first 75 words of 825 total…
