Answer:
The correct answer is a cancerous tumor.
Explanation:
Density-dependent inhibition refers to the phenomenon in which the crowded cells stop proliferating. In the process, the group of cells present in a region force competition for space, nourishment, and growth factors. Thus, when the cells are clumped together, they receive the signals to stop dividing further. Thus, in density-dependent inhibition, when the density is high no division of cells takes place.
Density-dependent inhibition is a process in which the growth of the cells is restrained to a specific limit of density, after that the growth gets prevented, probably due to cell-cell contacts. On the other hand, the tumor cells generally do not possess density-dependent inhibition, due to this, the cancer cells show unlimited growth without getting ceased. Therefore, in the given case, the source of the tissue sample is primarily a cancerous tumor.
Answer and explanation;
DNA molecules is a nucleic acid which carries genetic information for the synthesis of proteins that carry out various processes in all organisms and is found in the nucleus of a cell.
Messenger RNA on the other hand is a type of RNA that carries genetic information copied from DNA, for the purpose of protein synthesis.
DNA encodes the information necessary to produce the proteins needed by your body. To make these proteins, DNA first undergoes a process known as transcription.
Transcription is the process that takes place in the nucleus of a cell, where the information on the DNA strand is transferred to a molecules known as mRNA. This process is catalyzed by the enzyme RNA polymerase.
The mRNA is a type of RNA which carries the information from the DNA for protein synthesis. The mRNA moves from the nucleus to the cytoplasm to special organelles called ribosomes where proteins are synthesized.
