1. Two genetically identical copies of DNA
2. Finds an error in DNA, removes the incorrect nucleotide and replaces it with a correct one.
3. It is used as a copy/ "template" for replication in order to have two identical copies of DNA.
4. DNA helicase unwinds DNA double helix and Topiosomerase ensure there isn't too much unwinding.
5. Replication has a built on proofreading system - DNA polymerase removes the incorrect nucleotide and replaces it with a correct one.
Answer:
Explanation:
Pericentric inversion results in chromosome have extra copies of some genes while some genes do not have copies. It can result in slow growth rate.
If a man is heterozygous of pericentric and a woman is heterozygous of pericentric although they do not show symptoms there is 25% chance that their offspring will have it and 50% chance of them being a carrier.
T t × T t will give TT T t T t t t
If the father is not heterozygous of it but the mother is heterozygous they have 0% chance of having it and 50% chance of being heterozygous a carrier of the disorder
T t × TT will give TT TT T t T t
Because the interior of the lipid bilayer contains the nonpolar _____molecules__________, only small nonpolar substances are able to diffuse directly across the cell membrane
Answer:
Almost twice
Explanation:
Human being have estimate 24,000 genes, while fruit flies have an estimate of 14,000 genes: meaning it is almost twice
