What is the stage of the cell when DNA replication occurs?

No, the stage of the cell cycle when DNA replication occurs is not called telophase. DNA replication occurs in the S (Synthesis) phase of the cell cycle. Telophase is the last stage of mitosis or meiosis, when the nuclear envelopes re-form (it occurs at the same time as cytokinesis - which separates the cells).

What is an end replication problem?

The two strands of a DNA molecule are antiparallel to one another (the backbone of one strand runs from 5'-3' while the complimentary strand runs 3'-5'). Unfortunately, DNA polymerase, the enzyme responsible for replicating DNA, can only make DNA in a 5'-3' direction (and read DNA in the 3'-5' direction). Also, it needs a "primer" to give it a place to bind and start replication. So this creates a problem when synthesizing the 3'-5' stand because your enzyme will only synthesize 5'-3'. During replication this is solved by synthesizing small pieces of DNA ahead of the replication fork on the 5'-3' mother strand. Thus we have one daughter strand which is synthesized as a continuous piece of DNA (called the leading strand) and one daughter strand which is synthesized in small, discontinuous pieces (called the lagging strand). However, at the extreme end of the DNA, we run into another problem. The leading stand can be made to the very end, but the lagging strand cannot because you need the RNA primer upstream to begin each piece of the lagging strand DNA but at the end of the DNA there is nothing for this piece to attach to. Thus, the last section of the lagging strand cannot be synthesized and after several rounds of DNA replication, the DNA molecule gets smaller and smaller. This is "the end of replication problem" and it is solved by putting a DNA cap on the ends of DNA called a telomere which does not code for any protein, thus when this information is lost it does not have severe consequences for the cell.


How is cellular work done by ATP?

ATP is a molecule that stores and transfers energy within cells. When ATP is broken down into ADP and inorganic phosphate, energy is released, which powers cellular processes like muscle contraction, active transport, and chemical reactions. This energy release provides the fuel needed for cells to perform work.

Are only 2 ATPs produced for each NADH molecule that enters the last stage of respiration?

The NADH molecule produces of 2 ATPs during the last stage of respiration. Some think that three ATPs are created from the NADH, however, the last stage of respiration is different than ATP and NADH during electron transfers.

What is DNA-replication?

DNA replication is a process during which DNA double helix opens like a zipper , new nucleotides are added along both strands of DNA by enzyme DNA polmerase and at last two molecules of DNA are formed. It takes place in S phase of interphase .
