Answer:
The average size of the DNA fragments produced when this new DNA is cut by a restriction endonuclease with an eight-base recognition sequence would be 1679616.
Explanation:
Restriction enzymes can be described as the enzymes which are specific to certain DNA sites and cut the DNA from that particular site.
Normally, the average size of a DNA fragment cut by a restriction enzyme is calculated by the formula 4^{no.of base recognition sequence}.
As the number of bases has changed to 6 and the restriction enzyme has eight base recognition site then the formula will be:
6^{no.of base recognition sequence}
i.e
6^{8} = 1679616
I believe the process this question is talking about is Meiosis

Tangerines AmbitiousThere are a few hundred billion stars in our galaxy, the Milky Way and billions of galaxies in the Universe. One important technique in science is to try and sort or classify things into groups and seek out trends or patterns. Astronomers do this with stars.
So far we have discussed the luminosity and colour or effective temperature of stars. These can be plotted to form what is one of the most useful plots for stellar astronomy, the Hertzsprung-Russell (or H-R) diagram. It is named after the Danish and American astronomers who independently developed versions of the diagram in the early Twentieth Century.
In an H-R diagram the luminosity or energy output of a star is plotted on the vertical axis. This can be expressed as a ratio of the star's luminosity to that of the Sun; L*/Lsun. Astronomers also use the historical concept of magnitude as a measure of a star's luminosity. Absolute magnitude is simply a measure of how bright a star would appear if 10 parsecs distant and thus allows stars to be simply compared. Just to confuse things, the lower or more negative the magnitude, the brighter the star. By definition a star of magnitude 1 is 100 × brighter than one of magnitude 6. Our Sun has an absolute magnitude of + 4.8.

Answer:
The correct answer is option c, that is, Charles Yanofsky.
Explanation:
An American geneticist, Charles Yanofsky, worked as a faculty at Stanford University took part in the development of one gene-one enzyme hypothesis, and found attenuation, that is, a riboswitch mechanism.
In the mechanism, the messenger RNA modifies its shape in response to a small molecule, and therefore, changes its binding capability for the regulatory region of an operon and a gene. His studies suggested that genes and proteins are co-linear. If the section of the intron in the gene gets mutated, then the protein generated by the protein also gets mutated.
