The lagging strand is characterized by a series of short segments of DNA (Okazaki fragments) that will be joined together to for

scZoUnD [109]

Question is incomplete. Complete question has been attached.

Answer:

A) DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication.

Explanation:

DNA polymerase synthesizes the new DNA strand from the template strands. Both the strands in a DNA molecule act as templates, however both of them have different orientation. It was observed that 3'-5' template DNA produced a new DNA strand continuously in one step. However, 5'-3' template produced new DNA strand in fragments which were joined together later. This observation gave the idea that DNA polymerase is a directional enzyme. It synthesizes DNA in 5'-3' direction so 3'-5' template gave rise to a continuous DNA segment. However, for 5'-3' template, DNA polymerase had to synthesize in opposite direction i.e. 3'-5' which was not possible directly. So the enzyme replicates it in short separate fragments which are later joined by DNA ligase.

Which section of the heart receives deoxygenated blood? select one:

Tatiana [17]

Answer:

The right atria

Explanation:

The heart is the core organ of the circulatory system responsible for pumping blood by the contraction of cardiac muscles which is then conveyed to other parts of the body through blood vessels. The heart possesses four chambers of which the two upper ones are called ATRIA and the two lower ones are called VENTRICLE.

Each side of the heart contains one atria and one ventricle. The atria allows blood into the heart while the ventricle allows blood out of the heart. However, during the pumping process, deoxygenated (without oxygen) and oxygenated (with oxygen) blood enters and leaves the heart. The right ATRIA is responsible for receiving deoxygenated blood into the heart while the left ATRIA receives oxygenated blood into the heart.

a penny is tossed and comes up heads 7 out of 10 times. Is the probability that it will be heads on the next toss 70%? Why or no

jonny [76]

Answer:

I think it will because when you express 7/10 as a fraction it will result to 0.7, meaning the probability between 0 and 1 will be 0.7, therefore to express 0.7 as a fraction the answer will be 70%..

sorry if it's wrong
