The answer as of Castle Learning was choice 4, Enzymes.
Enzymes are used to cut and paste DNA from one source to another. Enzymes called restriction endonucleases are capable of cutting DNA at specific sites called restriction sites. These sites are typically 4 - 6 nucleotides in length and occur several times in the genome of almost all organisms discovered. Enzymes called DNA ligases are capable of pasting (or ligating) two strands to DNA together. DNA from one organism can be cut at specific locations using restriction enzymes and then pasted into a different source (like a plasmid for example) using DNA ligase.

No. The amount of DNA in human sperm cells is half of the amount found in body cells.
DNA in the human body is located in the nucleus of each and every cell in the human body.
g1, the cell grows rapidly and carries out its routine functions S, the DNA is copied g2, preperations are made for the nucleus to divide. Hollow protein fibers called microtubules are rearranged
This cannot be answered without reference to cell type etc. A human red blood cell has no DNA! A gamete cell has 1/2 quantity, a cell prior to cell division has double, a polyploid plant cell has many times more DNA than normal.
DNA is found in two organelles: the nucleus and the mitochondria. The amount of nuclear DNA is fixed and does not vary from cell to cell, but the number of mitochondria can affect the amount of mitochondrial DNA.
In one human cell, there are 2 metres of DNA. Which means that a human has about 200 trillion metres of DNA in their entire body. No... theres 3.6m of DNA per cell

Yes. The DNA is found in the nucleus of every cell. It's simply a case of extracting the DNA from the cell.
There are a trillion to 1000 trillion DNA in a human cell.

The cell is mostly made out of cytoplasm and also DNA.
DNA functions in every cell of the human body, and in every cell of every living thing on the earth.
