Which enzyme is mixed with a DNA sample before gel electrophoresis

Svetach [21]

Answer:

Restriction enzyme

Explanation:

Gel electrophoresis is a process or a technique in which fragments of DNA are separated in terms of their sizes.
<em><u>The restriction enzyme is mixed with a DNA sample before the process. The restriction enzyme cut DNA at specific points into fragments which can then be separated based on their sizes on an agarose gel.</u></em>
When current is applied to the gel DNA move towards the positively charged electrode since DNA is negatively charged, with shorter fragments migrating faster through the gel in comparison with large fragments.

The correct answer is that different genes are expressed in different cells.

The cellular differentiation is the process in developmental biology where a cell modifies from one kind of cell to another. Most generally the cells are modified to a more specialized kind. Differentiation takes place various times at the time of development of a multicellular species as it modifies from a basic zygote to a composite system of tissues and kinds of cells.
