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

-desoxyribonucleic acid is a polymer of nucleotides -Each nucleotide consists of a nitrogenous base, a peag, and a phosphate group -The sugar in deoxyribonucleic acid is a pentose sugar called deoxyribose -The different kinds of bases ar adenine, thyroxine, grand, and cytosine -In desoxyribonucleic acid, in that location is a 1:1 ratio of nucleotide bases: return of adenine = fig of thymine and number of guanine = number of cytosine -DNA consists of 2 strands in a shape called a double lock         -Double helix is 2-nm in diameter         -The strands omit a sugar-phosphate backb ace         -The devil strands argon held to conquerher by enthalpy bonds         -The rungs of the helix consist of purine/pyrimidine rings -Adenine and guanine are purines         -Purines have two organic rings -Cytosine and thymine are pyrimidines         -Pyrimidines have a adept organic ring -Pyrimidines check with purines to change rungs of helix (adenine with thymine and guanine with cytosine)         -Adenine and Thymine r to each one 2 enthalpy bonds         -Guanine and Cytosine form 3 hydrogen bonds -The helix makes one full pull ever 3.4 nm along its length -Bases are stacked .

34 nm apart         -Ten layers of base pairs in each turn of the helix -Replication is explained by the Semiconservative model         -When a double helix replicates, each of the two daughter tinges go out have one old strand derived from the parent molecule and one fresh made stra nd -DNA reproductive memory involves unzipp! ing the DNA molecule into 2 strands         -Each strand acts as a template to summon a new, complementary strand                  -Results in two identical double-stranded molecules of DNA -How DNA replication occurs         -Helicase unwinds the DNA forming a replication fork (Y-shaped percentage where the new strands of DNA are elongating)         -Single-stranded DNA medical dressing proteins bar single strand of DNA from recombining         -RNA Primase initiates DNA replication at special nucleotide sequences called origins of replication. RNA Primase uses... If you want to get a full essay, order it on our website: OrderCustomPaper.com
