This process is called “crossing over.”
It will increase genetic diversity in gametes, so option A would be correct I believe !
1. Griffith in his experiment used two related strains of bacteria (Streptococcus pneumonia), known as R and S and mice, trying to develop a vaccine against pneumonia. R strain-formed nonvirulent, rough-edged colonies
S strain- rounded and smooth colonies, with sugar protection coat, virulent
Mice that were injected with S strain developed pneumonia and died.
But, when mice were injected with heat-killed S strain it did not cause disease in mice.
The next part of experiment is the injection of combined harmless R bacteria with harmless heat-killed S bacteria. The result was that the mouse developed pnenumonia and in blood sample from the dead mouse, living S bacteria were found.
2. From his experiment, Griffith concluded that injected together, R strain and S strain bacteria most likely “communicate”. The R-strain bacteria took "transforming principle" (we know today that this is genetic material DNA) from the heat-killed S bacteria which allowed them to "transform" into virulent bacteria.

protein.</u></h3><h3><u>
Explanation:</u></h3><h3>Due to the definition of the central dogma, another way of putting it is that the central dogma follows the flow of information from DNA to protein.</h3><h3>I hope I helped, please let me know if it was right!</h3>
<span>The cell theory is an explanation of what cells are and why they exist. The three main parts are: 1) All living things are made of cells and their products, 2) New cells are created by old cells dividing into two, and 3) Cells are the basic building units of life. In 1665, Robert Hooke observed, with the aid of a crude compound microsope, the structure of a thin slice of cork. The structure resembled stacks of hat boxes, or holding cells, so he called what he observed "cells". In 1674, Anton von Leeuenhoek observed, in a sample of pond water, small animal-like creatures swimming around. He probably was looking at Spyrogira, but he called these small organisms "animal-cules". Theodore Schwann and Matthias Schleiden are responsible for formulating the first two parts of the cell theory, which was a scientific explanation of what these scientists had observed up to this point. A few years later, Rudolph Virchow added the third part of the cell theory, that all things are composed of these basic building blocks called cells.</span>
