Explanation:
DNA replication is a process common to both prokaryotes and Eukaryotes with few differences and similarities.
<u>Differences:</u>
1. Origin of replication (ori) : is a sequence of the genome where initiation of replication takes place. Prokaryotes have only single ori while eukaryotes have multiple ori as the DNA is large in eukaryotes so require multiple or to replicate whole DNA.
2. Replication site: prokaryotes lack nucleus where DNA is present in the cytoplasm while eukaryotes posses nucleus which encloses DNA. Therefore, replication takes place in cytoplasm in prokaryotes while in the nucleus in eukaryotes.
<u>Similarities:</u>
1. Enzymes: both posses same enzymes for DNA replication like DNA helicase, primase, polymerase.
2. The direction of synthesis: the enzyme DNA polymerase synthesizes new strand of DNA in the same direction that is 5' to 3' direction.
Thus, marked answer in the table are correct answer.
Answer:
It drains into a larger lymph trunk, which returns it to the subclavian veins.
Explanation:
Answer:
The correct answer is option e. "None of the above".
Explanation:
The Hershey-Chase experiment helped to prove that DNA was the genetic material, by specifically labeling the DNA material of a bacteriophage with phosphorus-32. In this experiment the lambda phage is labeled with heavy and light Cl. CI-36, the one that is heavy and radioactive, corresponds to Chlorine-36. Chlorine is not an element found in DNA such as phosphorus, therefore lambda DNA will not be labeled and no radioactivity will be detected.
Binary fission is for reproduction of a cell by division into two equals parts
<em>G1, S and G2 phases are all cumulatively referred to as interphase involving the growth of a cell and the replication of its DNA. Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents. The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. The S phase only begins when the cell has passed the G1 checkpoint and has grown enough to contain double the DNA. S phase is halted by a protein called p16 until this happens.</em>
