Answer:
The DNA polymerase is the enzyme which copies in the direction of 5' to 3' in the leading strand and in case of lagging stand it is opposite. that is from the 3' to 5'.
Replication in the 3' to 5' takes place in the fragments which is laid by the Okazaki fragments. These small fragments are kept together by the help of the enzyme known as DNA Ligase. So, called as discontinues
Incase of leading strand, the strand is in the same direction of the for the process of replication (5' to 3'). So it is continuous.
Hence, the whole process is a combination of continuous and discontinuous DNA synthesis.
Answer:
I agree with her.
Explanation:
ATP definitely is the most widely used high energy molecule - especially for cells. But, it is not absolutely necessary for some "passive" cellular mechanics. We can look at passive diffusion of cellular processes which may include; passive diffusion of water, or sugar molecular across a cellular membrane.
In aerobic respiration, the final electron acceptor in the electron transport chain is oxygen. It accepts two electrons and a molecule of water is formed as a by product.
In anaerobic respiration, the final electron acceptor in the electron transport chain is pyruvate. Anaerobic respiration commonly occurs in the muscle tissue of animals as a result of intense activity or exertion. Pyruvate is used as makeshift electron acceptor in place of oxygen and is reduced or converted to lactic acid.
The theory that proposes that the universe emerged form an explosion (The Big Bang) is known as the Big Bang Theory.

Answer:
It could happen through mutation
Explanation:
<em>A segment of DNA after many cell divisions could have more base pairs than it originally did as a result of mutation.</em>
Mutation is generally defined as a sudden change to the DNA sequence of a cell. This change could be of difference forms, including:
- <em>Addition of bases</em>
- <em>Deletion of bases</em>
- <em>Substitution of bases</em>
<u>Addition of bases to a DNA will generally lead to a longer base pairs in the DNA, deletion will lead to a shorter base pairs while substitution will only lead to a change in the base sequence without any change in the length of the DNA.</u>
