DNA Replication Questions and Answers (Q&A)

None of the answers above accurately answer the question. DNA stands for deoxyribonucleic acid and is a self-replicating material that nearly all living organisms have. DNA carries the organism's genetic information. In DNA, the neucleotides of one strand pair up with specific neucleotides of another strand.

Purine Adenine (A) always pairs with Pyrimidine Thymine (T), and Pyrimidine Cytosine (C) always pairs with Purine Guanine (G). These rules of base pairing, also known as nucleotide pairing, make it easy to immediately deduce the neucleotides of the missing strand in a pair. For a DNA sequence of ATTGCGACCGAG, you would find the corresponding DNA sequence of TAACGCTGGCAC.

Ligase is the enzyme that will fix this lagging strand. When DNA is replicated for cell division, only one of the strands can be replicated in one continuous strand. The other half of the DNA is replicated in short spurts. This short spurt results in the kind of thing seen in the picture. The ligase binds the short, lagging pieces. The ligase will also fix any missing pieces in a DNA strand so long as it has a template to work with. However, there’s also a kind of ligase that’ll fix a break occurring in both strands of DNA at the same place.

In non-technical terms, a ligase will make the same kind of phosphorous base that is used to make the backbone of the DNA chain. In short, that’s how it binds the DNA.

The function of DNA Polymerase III is that it performs 5'-3' polymerase function, which helps transcribe DNA into RNA. It can also proofread any mistakes made during replication. It was discovered in 1970 by biochemist Thomas Kornberg and Malcolm Gefter. There are three functions of DNA Polymerase III.

The first is that it adds deoxyribonucleaosde triphosphates to the DNA strand. Its; second function is catalyzing phosphodiester bonds. The third and final function is that the DNA polymerase III proofreads each deoxyribionucleotide. DNA Polymerase III is also a componet of the replisome, which is responsible for carrying out the replication of DNA.

DNA replication is the process wherein the DNA makes a copy of itself. This usually occurs during cell division. The double helix structure will be unzipped first then the hydrogen bonds will be broken down. The separated structure will then create the replication fork form. The two new strands will serve as the new, replicated DNA.

Cell replication is important because if this does not occur, this will lead to the death of the cells. It is also important that DNA will be copied so that no mutation will occur as new cells are formed. This will ensure that people will be getting healthy cells.

A primase is a type of lagging strand template which means that it will not be able to do its replacement properly. A polymerase I, on the other hand, will have the ability to extend so that the RNA segments will be removed. This means that the right answer is C. It will then extend to fill the gaps wherein the RNA fragments are removed.

This can form the needed fragments. This is when the RNA primers will be removed and they will be replaced by DNA. The DNA ligase will be in charge of connecting the various fragments of the DNA. Polymerase III will be used before Polymerase I.

The correct answer is option D
The correct order of cell division from interphase through cytokinesis is denoted with the images in order from B, D, A, C, F and E

The interphase (B) is the first stage in the cell cycle; it prepares the cell for division. At this stage, the cell grows and matures and the DNA is also copied.

After interphase, comes mitosis when the nucleus of the cell divides into two identical nuclei. Mitosis is further divided into phases which include: Prophase (D), prometaphase, metaphase (A), anaphase (C) and telophase (F).
After these phases comes cytokinesis (E) which divides the cytoplasm, organelles and cell membrane into two.

The process of DNA transcription involves transcription factors linking onto the promoter region of the DNA strand on the template strand. then the RNA polymerase is able to find the strand of DnA, and attaches to the template strand. Next, the RNA polymerase goes along the DNA strand, adding complimentary base pairs to the template strand, with U going to A. Once the RNA polymerase reaches the stop codon, the RNA polymerase releases. Then the strand of nucleotides has the introns spliced, leaving the exons to make up the strand of mRNA.
