A liar always knows he is lying, and that is why liars travel in packs: in order to be reassured that the judgement day will never come for them
Answer: Cell membrane
Explanation:
The cell membrane has the ability to transfer the molecules from the exterior of the cell to the interior of the cell.
The cell membrane is semi permeable which means only selected molecules will pass through the cell membrane.
The molecules and substances that are synthesized inside the cell needs to be transported from inside to outside via cell membrane.
Answer and Explanation:
A restriction enzyme is a type of endonuclease enzyme that recognizes a specific short nucleotide sequences on the DNA and cuts the DNA only at palindromic sites. There are different types of restriction enzymes:
1. Type I restriction enzyme – It cuts at sites far from the recognition site and requires both ATP and S-adenosyl- L-methionine as cofactor to function.
2. Type II restriction enzymes – It cleaves at short-specific distances from the recognition site and mostly requires magnesium to function.
3. Type III restriction enzymes – It recognizes two separate non-palindromic sites and cleaves at 20–30 base pairs away from a recognition site. It requires both ATP and S-adenosyl-L-methionine .
The restriction enzymes cleave DNA sequences producing either sticky or blunt ends that can be ligated with other sequences.
