Ascientist wants to insert a new gene into a bacterium. what is the first step in this process?

In an experiment, researchers first insert a piece of DNA like a gene, into a circular piece of DNA called a plasmid.

The correct answer is- cutting the gene out of DNA with enzyme.

Explanation:

To insert a gene into a bacteria first the gene of interest should be cut out of the DNA sequence by the help of an enzyme called restriction endonuclease. A specific restriction endonuclease cut the gene of interest by identifying restriction site and making cut at that particular restriction site.

Then this gene of interest is ligated in a plasmid vector which have its own origin of replication and a selection marker. Then this plasmid vector having the gene of interest is transferred or inserted into bacteria by methods like heat shock, gene gun, etc. After transformation, it will express proteins in bacteria according to the gene of interest it has.

So the first step in this process is cutting the gene out of DNA with enzyme.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

paper covers rock.

explanation:

rock only smashes scissors.
