 | Okay then how long are DNA Strands? | |
|
| Well a DNA strand runs 3' to 5'. The other runs 5 to 3'. The two strands are copied differently | |
|
|
|
|
|
|
| why is one longer than the other? | |
|
| One strand called the leading strand, is made longer as the origninal DNA unwinds and nucleotides are added tp its 3' end. | |
|
|
|
|
|
|
| Okay tell me more | |
|
| The other strand called the lagging strand becomes longer as small pieces called Okazaki fragments are added to the 3' to 5' direction. | |
