What is the last step in DNA replication called?

sergey [27]3 years ago

The next we have to do is to shed light into the mystery of the steps of DNA Replication<span>of the Eykaryotes. </span>

<span>1)The first major step for the </span>DNA Replication<span> to take place is the breaking of hydrogen bonds between bases of the two antiparallel strands. The unwounding of the two strands is the starting point. The splitting happens in places of the chains which are rich in A-T. That is because there are only two bonds between Adenine and Thymine (there are three hydrogen bonds between Cytosine and Guanine). </span>Helicase<span> is the enzyme that splits the two strands. The initiation point where the splitting starts is called "origin of replication".The structure that is created is known as "</span>Replication Fork<span>".
</span>2) One of the most important steps of DNA Replication<span> is the binding of </span>RNA Primase<span> in the the initiation point of the 3'-5' parent chain. </span>RNA Primase<span> can attract RNA nucleotides which bind to the DNA nucleotides of the 3'-5' strand due to the hydrogen bonds between the bases. RNA nucleotides are the primers (starters) for the binding of DNA nucleotides. 
</span>3) The elongation<span> process is different for the 5'-3' and 3'-5' template. a)</span>5'-3' Template<span>: The 3'-5' proceeding daughter strand -that uses a </span>5'-3' template<span>- is called </span>leading strand<span> because </span>DNA Polymerase ä<span> can "read" the template and continuously adds nucleotides (complementary to the nucleotides of the template, for example Adenine opposite to Thymine etc).</span>

Explain why it is important for dying cells to be properly removed
victus00 [196]
Cells within the body are properly arranged and their production uses up resources of the body. For example, red blood cells use iron while being produced. The body must dispose of cell properly to maintain the orderly arrangement of cells; for example, if dead skin cells were not removed, we would lose feeling in our skin due to the layer of dead cells. Moreover, the body must work to minimize wastage. This is why some of the iron from red blood cells is removed and reused.

Mandarinka [93]

Answer:

Options I and II

Explanation:

Evolution refers to the changes that occurs in the morphology, appearance and behavior of an organism over a due course of time. This changes occurs due to the natural selection method, where organisms undergoes changes and adapts to the newly habitable environment.

The above given options I and II are the evidences of evolution. The similarities in terms of bones and their defined structure between the bat wings and porpoise fins are signs of evolution that has taken place over a definite span of time. Also, the changes in the various breeds of dog that are caused by the artificial selection method is also an example of evolution.

Thus, the correct answers are options I and II.
