Day 15: The structure of DNA definitions of enzymes

Today we learned more about the structure of DNA. We learned that DNA can be split like with an enzyme called helicase and then use other enzymes to create a new strand using RNA. Here are the definitions of the differnt enzymes used.

Helicase- seperate strands of DNA by breaking the hydrogen bonds in between the nucleotide bases. It also uses energy from hydrolysis.

DNA Polymearse  I - This is an enzyme that participates in the replication of DNA. When the replication process takes place this enzyme removes the RNA primase and fills in different nucleotides in between the Okazaki fragments and this moves in the 5' to 3' direction.

DNA Polymearse III - This enzyme is involved in replication as well and has proofreading capabilities that works 3' to 5' and this enzyme also works at the replication fork.

RNA Primase - This is an enzyme that is important in the replication in DNA because no DNA polymearse can function as a starter key for the synthesis of a DNA strand. You always need this enzyme to function after the RNA segments are elongated by DNA polymerase.

Ligase- This enzyme is the catalyse for the joining of two large molecules and it forms a new chemical bond between them. This is usually accompanied by hydrolysis (adding water) to the smaller chemical groups that rely on one of the larger molecules.
