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

Answer:
Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.
