Transcription in both eukaryotes and prokaryotes is similar because

Answer;Both prokaryotic and eukaryotic transcriptions use a common enzyme, RNA polymerase, to transcribe DNA into RNA.In both prokaryotes and eukaryotes, transcription begins with the binding of transcription factors to the promoter site on the DNA.Explanation;Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA. The process occurs in both eukaryotes such as human beings and prokaryotes such as bacteria.However; prokaryotes and eukaryotes have incredible similarities and differences in transcription. Among the similarities includes; the fact that Both prokaryotic and eukaryotic transcriptions use a common enzyme, RNA polymerase, to transcribe DNA into RNA and also In both prokaryotes and eukaryotes, transcription begins with the binding of transcription factors to the promoter site on the DNA.Additionally, there are many differences between eukaryotic and prokaryotic transcription; for example, Prokaryotes have only one RNA Polymerase, while eukaryotes have three, etc.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
