Term
|
Definition
| Refers to the relation between the two nucleotide strands of DNA in which each purine on one strand pairs with a specific pyrimidine on the opposite strand (A with T, and G with C). |
|
|
Term
|
Definition
| Refers to a characteristic of the DNA double helix in which the two polynucleotide strands runs in opposite directions. |
|
|
Term
|
Definition
| The 5' or 3' of a mRNA strand. The 5' being the Amino (NH3) and the 3' being the Carboxyl (COOH) end. |
|
|
Term
| Semiconservative replication |
|
Definition
| Replication in which the two nucleotide strands of DNA separate, each serving as a template for the synthesis of a new strand. |
|
|
Term
| Semidiscontinuos replucation |
|
Definition
| Refers to half of the strands being leading and the other half are lagging strands. Replaction of the lagging strand in the direction opposite that of unwinding, which means that DNA must be synthesized in short streches (Okazaki fragments). |
|
|
Term
|
Definition
| Bacterial DNA polymerase that removes and replaces RNA primers with DNA nucleotides. |
|
|
Term
|
Definition
| Bacterial DNA polymerase that synthesizes new nucleotide strands off the primers. |
|
|
Term
|
Definition
| Enzyme that synthesizes a short stretch of RNA on a DNA template; functions in replication to provide a 3'-OH group for the attachment of a DNA nucleotide. |
|
|
Term
|
Definition
| Enzyme that catalyzes the formation of a phosphodiester bond between adjacent 3'-OH and 5'-phosphate groups in a DNA molecule. |
|
|
Term
|
Definition
| Protein that unwinds double-stranded DNA by breaking hydrogen bonds. |
