Answer:

reverse transcriptases.

Explanation:

Reverse transcriptase is an enzyme that makes DNA copies of the RNA template. To make the libraries of the genes that are expressed, the enzyme reverse transcriptase is used. The researcher first extracts mRNA from the cells of target organisms and then uses the enzyme reverse transcriptase to prepare complementary DNAs which are also called cDNAs. The enzyme reverse transcriptase add dNTPs to make a complementary DNA strands.

A single celled paramedic is placed in a hypotonic solution.what will happen to the cell?​
Gnesinka [82]

When a single celled paramedic is placed in a hypotonic solution, the cell swells and then bursts.

<h3><u>Explanation:</u></h3>

Hypotonic solutions are the solutions that contain more water than present in a cell. Hence, when an animal cell is placed in a hypotonic solution, the cell will undergo osmosis. Osmosis is the movement of any form of solvent through a plasma membrane to a higher concentration from a lower concentration until the the external concentration matches the inner one.

To put it in simple words, when a single animal cell is places in a solution which has more water than other solutes, the water will invade the cell until it can accumulate the amount that equalizes the inner and external concentration. The cell will begin to swell up until there is no more space and finally, it will burst. For example, when you put water on a cloth that has blood stain on it, the cells will burst and make the stain worse than before.
