When a single cell undergoes many mitotic divisions in the nucleus, producing many daughter cells, it has conducted B) Multiple fission.
Multiple Fission is a type of asexual reproduction in which the parental body divides into many daughter cells simultaneously during the unfavorable conditions to increase the chances of survival of daughter cells.In this, the reproductive unit is whole parental body.
Hope this helps :)
Identical
As long as there were no mutations or horizontal gene transfer
Out of the choices given, the step that caused an aerobic atmosphere during the history of Earth was the origin of photosynthetic prokaryotes. The correct answer will be D.
The question is incomplete as the options are not provided which are:
RNA replicase is present in the viral capsid.
The RNA genome is of the plus sense and RNA replicase is present in the viral capsid.
The new bacteriophage is a retrovirus.
The RNA genome is of the plus sense.
Answer:
The RNA genome is of the plus sense and RNA replicase is present in the viral capsid.
Explanation:
The bacteriophage is the virus particles which are composed of the genetic material enclosed in the Capsid protein. The Bacteriophage virus infects the bacteria and uses their replication machinery to replicate themselves.
In the given question, all the proteins along with RNA for translation or ribosomes is provided. The single-stranded RNA is first their genome copied by the RNA replicase and the positive strand, therefore, acts as the mRNA. This mRNA is then translated into the protein sequence and a new virion is produced.
Thus, the selected option is correct.
