New DNA molecule compromised of one original/old strand and one new strand.
What are 2 enzymes and their functions which are involves in the replication of DNA?
DNA helicase unzips the double stranded DNA by breaking the hydrogen bonds between the strands.

No

The movement of water into the potato cells is equal to the movement of water out of the potato cells.
What is the name of the bond that forms between two nucleotides?

( uncertainty/ value ) x 100
Name the stages of mitosis in the correct order
Prophase, Metaphase, Anaphase, Telophase
In what stage of meiosis does crossing over occur?
Prophase 1
In what stage of meiosis does independent random assortment occur?
Metaphase 1
What is genetic variation?
The variety of alleles - offspring will have alleles from more than one parent.
In % uncertainty question what do you do if there is more than one value?
Multiple the uncertainty by the number of values.
