A cell has the following molecules and structures enzymes DNA ribosomes plasma membrane and mitochondria It could be a cell from?
a bacterium or a plant, but not an animal
Whatn functions do restriction enzymes have in living cells?
In the living bacterial cell, these enzymes destroy the DNA of certain invading viruses (bacteriophages), thus placing a "restriction" on the number of viral strains that can cause infection; the bacterium's own DNA is protected from cleavage by methyl (-CH3) groups, which are added by enzymes at the recognition sites to mask them.
What are the three biological molecules in the cell that DNA must be separated from?
The three biological molecules in the cell that DNA must be separated from are the cell membrane, lipids, and enzymes. The DNA is found in the nucleus of the cell.
Enzymes used to cut DNA molecules in recombinant DNA researsh are?
restriction enzymes
What are the differences between the sugar phosphate arrangement in the backbone of the DNA from the plant mammal and the bacterium?
There is no difference between the sugar-phosphate arrangement in the backbone of the DNA from the plant, mammal, and bacterium. What makes plant, mammal, and bacterium different is the sequence of the DNA nucleotides.
The bacterium containing functional frog DNA would be classified as a?
transgenic organism
A scientist wants to insert new gene into a bacterium what is the first step in this process?
cutting the gene out of the DNA with enzymes
What is a collection of cells containing DNA fragments produced by restriction enzymes and incorporated into plasmids?
A DNA LibraryA collection of cells containing DNA fragments produced by restriction enzymes and incorporated into plasmids is called a DNA library. RNA can manufacture DNA via the action of reverse transcriptase.

A gelatinous matrix inside the chloroplast containing ribosomes DNA and enzymes called?
stroma

Can virus get a bacteria?
Yes- Bacterial viruses are called bacteriophages. Some examples are T4 and T7 phages. They are complex DNA viruses that attach themselves to the cell surface and then inject their DNA to the inside of the bacteria. Bacteria have enzymes called restriction enzymes that cleave DNA at specific sites called restriction sites. These enzymes are the bacterium's defense against phages.

What is it called when you insert DNA in to a bacterium?
Recombinant DNA
A ring of DNA found in a bacterium in addition to the bacterium's main chromosome is?
It's called a plasmid. The ring of DNA
