You begin an experiment with two populations of E. coli that are each composed of 100 cells. The cells are genetically identical
Wewaii [24]

Answer:

C) Initially mutation will be the only source of variation in the population

Explanation:

In this experiment, mutation will be the only source of variation in the population.

Therefore, natural selection cannot begin operating immediately on the population because there was no initial variation.

Also initial differences in the population will not be as a result of sexual selection.

Finally, mutation is a random process. Despite the two populations being identical they will accumulate different mutations. Therefore after 100 generations the two populations will not be genetically identical.

zlopas [31]

During the process of gene expression, the DNA to RNA step is known as transcription while the RNA to protein step is known as translation.

Gene expression is a process which involves the synthesis of a functional gene product by using the information present in the genes.

Transcription is a process which involves the synthesis of a RNA from the DNA. In eukaryotic cells, the transcription occurs in the nucleus whereas in prokaryotes the transcription occurs in the cytoplasm of the cell.

Translation is the process by which the RNA is converted into a protein. The translation in prokaryotic cells occurs in the cytosol of the cell whereas in eukaryotic cells, the translation occurs in the ribosomes.
