Question

Rob Dunn noticed that the prokaryotes his team discovered in the belly buttons of volunteers were able to quickly take over an area due to their rapid growth rate. Which of the following statements explain why prokaryotes are able to divide so fast?

(a) DNA replication is faster,
(b) no organelle,
(c) microscopic in size, smaller than eukaryotic cell, (d) slow metabolic rate

Answer 1

DNA replication is faster and microscopic in size, smaller than eukaryotic cell.

Explanation:

The three domains of life are archaea, bacteria and eukarya. The two main biological division are prokaryotes and eukaryotes. The organisms that lacks the complete nucleus are included in prokaryotes.

The DNA replication is quite fast in prokaryotes as compared to eukaryotes because of small genome size, transcription is coupled with the translation and no post transcription modification is present in prokaryotes. The size of prokaryotes is quite small as compared with eukaryotes and shows the fast rate of diffusion.

Thus, the answer is option (a) and (c).
