Answer:DNA replication is the copying of DNA that occurs before cell division can take place. After a great deal of debate and experimentation, the general method of DNA replication was deduced in 1958 by two scientists in California, Matthew Meselson and Franklin Stahl.
DNA Replication. DNA replication faithfully duplicates the entire genome of the cell. During DNA replication, a number of different enzymes work together to pull apart the two strands so each strand can be used as a template to synthesize new complementary strands. The two new daughter DNA molecules each contain one pre-existing strand and one newly synthesized strand. Thus, DNA replication is said to be “semiconservative.”
You didn't really provide any possible answers here. However, it's very easy to say that the responsible actors for impulse transmission across the synapses from one nervous cell to another nervous cell is what we call neurotransmitters. These are special molecules that can have different effects when binding onto the required receptor sites.
The correct answer is: The cell is producing a large amount of proteins.
The nucleolus is the largest structure in the nucleus of eukaryotic cells with the main function in ribosome biogenesis. It includes the steps of ribosomal RNA (rRNA) transcription, pre-rRNA processing and ribosome subunit assembly.
Answer:
A:1 only.
Explanation:
In order for a nuclear power plant to be decommissioned safely, components have to be taken apart and cleaned to reuse in a different location.
Answer:
A. One cell took over another cell
Explanation:
Mitochondria is an organelle present in a eukaryotic cell that performs the function of producing ATP molecules from the available substrates in the cell.
The mitochondria organelle has its DNA other than the cellular DNA which shows that it was once an independent organism. This was proved by the endosymbiotic theory that during the formation of the eukaryote cell, the proto-eukaryote engulfed the chemosynthetic bacteria which later formed the symbiotic relationship with the cell and evolved into the mitochondria.
Thus, Option-A is the correct answer.
