It is important because it helps to understand the vital connections between plants and animals
The structure in cells that contains DNA and protein is the nucleosome, found in the nucleus. In the nucleus of the cell, DNA is exists in the form of a long helical thread. It order to fit inside the nucleus, the DNA thread must be compressed enough to do so.
The cell accomplishes this by wrapping the DNA thread around a protein called histone. A single unit of DNA and histone octamer (called octamer because it consists of 8 proteins) is called a nucleosome.
The entire stretch of DNA in an average human cell is about 2 meters in length and would never fit inside a cell if not for histone proteins.
D. So that they produce a complimentary sticky end to each other
E. Dna ligase is used for linking together the plasmid with the desired gene
11. Because DNA contain phosphate group which is a negative recharge, so it will attracted to the anode.
12. Because shorter DNA molecules means less Mr so the shortest length of DNA move faster
13. Denaturing the DNA into 2 single stranded of DNA at 95°, then add primer after cooling it at 65°, after that DNA polymerase is added so that the DNA polymerase will add extra basses across the dna strand.
