Term
|
Definition
| 2 strands of nucleotides twisted into a double helix |
|
|
Term
|
Definition
| deoxyribose sugar, phosphate and a base (A,T,C or G) |
|
|
Term
| Deoxyribose has a base attached to |
|
Definition
| its carbon 1, and a phosphate attached to its carbon 5 |
|
|
Term
| The DNA sugar-phosphate backbone is held together by |
|
Definition
|
|
Term
| The 2 DNA strands are antiparallel |
|
Definition
| with deoxyribose sugar and phosphate at 3’ and 5’ ends of each strand |
|

|
Term
|
Definition
| tightly coiled DNA packaged around bundles of protein (Histones) |
|
|
Term
| Replication of the DNA template strand |
|
Definition
| with the 3’ end is continuous and forms the “leading strand” |
|
|
Term
|
Definition
| can only grow by adding nucleotides to its 3’ end |
|
|
Term
| DNA polymerase brings about |
|
Definition
| the formation of the sugar-phosphate bonds |
|
|
Term
|
Definition
| fragments of DNA together to form the lagging strand |
|
|
Term
| Requirements for DNA Replication are: |
|
Definition
| DNA, Primers,Enzymes, DNA nucleotides and ATP |
|
|
Term
|
Definition
| Deoxyribose at the 3’ end and phosphate at the 5’ end of each strand |
|
|
Term
|
Definition
| a short sequence of nucleotides |
|
|
Term
| Replication of the lagging strand |
|
Definition
| is discontinuous as this strand starts with the 5’ end |
|
|
Term
| In the first stages of DNA replication |
|
Definition
| the DNA double helix unwinds and the weak hydrogen bonds between bases break |
|
|
Term
| Primers are required to create |
|
Definition
| an existing chain for DNA polymerase to work on |
|
|
Term
|
Definition
| the DNA must be replicated |
