Answer:
For the difference of the two: Bacteria contain peptidoglycan in the cell wall; archaea do not. The cell membrane in bacteria is a lipid bilayer; in archaea, it can be a lipid bilayer or a monolayer. Bacteria contain fatty acids on the cell membrane, whereas archaea contain phytanyl.
Answer:
DNA polymerases are involved in the production of new DNA molecules while RNA polymerases are involved the transcription of DNA to mRNA.
Error correction is not necessary in RNA polymerase as compared to DNA polymerase because
1. The production of mRNA from DNA is for a period of time, that is, it is finite and when it is converted to proteins, it can be degraded. But the DNA replication is from generation to generation as it is inherited
2. The process of transcription is so fast. Thus, just few number of transcripts will have errors compared to the number produced.
Answer: It's about things happen
Explanation:
Answer:
The elephant and the sheep exhibit higher sequence similarity because they are more closely phylogenetically related
Explanation:
The elephant and the sheep are mammals, while the crocodile is a reptile, being the mammals the most inclusive group among these three species and it appeared later in evolution. Mammals are organisms that have shared evolutionary features such as warm blood, they produce milk and have hair
Dividing a cell into more than one cell is called splitting.
