Term
|
Definition
| site where DNA replication begins |
|
|
Term
|
Definition
| enzymes that untwist the double helix of DNA at replication forks, separating the two strands and making them available as template strands |
|
|
Term
| single strand banding proteins |
|
Definition
| proteins that bind to the unpaired DNA strands during DNA replication, stabilizing and holding them apart while they serve as templates for the synthesis of complementary strands of DNA |
|
|
Term
|
Definition
| during DNA replication, topisomerase helps to relieve strain in the double helix ahead of the replication fork |
|
|
Term
|
Definition
| several complementary strands of RNA added to the lagging strand of DNA by RNA polymerase. |
|
|
Term
|
Definition
| an enzyme that joins DNA neucleotides to make a primer during DNA replication, using the parental DNA strand as a template |
|
|
Term
|
Definition
| enzymes that catalyze the elongation of new DNA by the addition of neucleotides to the three prime end of an existing chain |
|
|
Term
|
Definition
| DNA can only replicate from the 5 prime to the 3 prime end |
|
|
Term
|
Definition
| a short segment of DNA synthesized away from the replication fork on a template strand during DNA replication. Many such segments are joined together to make up the lagging strand of newly synthesized DNA. |
|
|
Term
|
Definition
| A linking enzyme essential for DNA replication; catalyzes the covalent bonding of the three prime end of one DNA fragment ( such as an Okazaki fragment) to the five prime end of another DNA fragment, such as a growing DNA chain |
|
|
Term
|
Definition
| The tandemly repetitive DNA at the end of a eukaryotic chromosome's DNA molecule; protect organism's genes from being eroded during successive rounds of replication |
