Which is the function of the DNA helicase enzymes in the DNA replication process?
DNA helicase "unzip," or separate, a strand of DNA at positions called origins. This means that the hydrogen bonds between complementary base pairs are removed (DNA is double stranded!). When they separate double-stranded DNA into single strands, it allows each strand to be copied (replication). DNA helicases use the energy stored in a molecule called ATP to break the bonds, which serves as the energy currency of cells.
A certain restriction enzyme digest results in DNA fragments What sizes 4000 base pairs 2500 base pairs 2000 base pairs 400 base pairs?
4000: 2500: | 2000: 400: | (the amount of strands represents the size of the DNA strands)
Why aren't DNA strands always six base pairs long?
They are always six base pairs long.
Identical pairs of alleles are called what?
homozygous
What is a molecole that consists of two complimentary strands connected by base pairs?
DNA
Why does DAN have to replicate before a cell can divide?
is DAN have to reprice , the DAN molecule unzips of the base pairs
Once a DNA molecule unzips exposed nitrogen base pairs have a strong attraction to each other?
true

They are always six base pairs long.
The two strands of DNA molecules are held together by?
base pairs
Identical pairs of alleles are called what?
homozygous
How are the 2 nucleotide strands connected?
In drawings of DNA the lines connecting the two strands represent base pairings. DNA is made up of four base pairs. These four pair up A-T and C-G exclusively.
How many pairs of equal angles has a parallelogram?
There will be two pairs. It is possible for all four angles to be identical.
When a trait has two identical alleles what is it called?
Homologous pairs
What holds two strands of dna molecule to each other?
The two strands of DNA are held together by hydrogen bonds between the nitrogen base pairs.
What type of bonds holds DNA strands together?
DNA strands are held together by hydrogen bonds.
