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:
a. the rough endoplasmic reticulum
Because it is the site of protein synthesis.
and all of the other organelles have no relation to protein and handling especially peroxisomes which detoxifies h202 and helps with intracellular digestion similar to the lysosomes and microtubules only function is for locomotion of prokaryotic cells and some eukaryotic cells like the sperm cell also they make up spindle fibers used to bind and separate chromosomes/chromatids in mitosis and meiosis.
Answer:
a cell wall (because a plant cell is less rigid than an animal cell)
- a large central vacuole (where plant cells store water)
- chloroplasts (which plants use to carry out photosynthesis)
Explanation:
Answer: You can add neutral solutions with a pH of 7, like water. Water will dissolve the alkaline/acidic pH to near 7 and 8, which are safe to drink.
Hope this helps you!
Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot.
