Which of the following is one role of RNA polymerase during transcription?
A- to break down an already existing protein
B- to produce a start sequence
C- to build a molecule of mRNA
D- to switch uracil with thymine on the exposed gene
My choice is C.
I agree with your answer choice.
Thank you! :)
You are correct! One of the roles of RNA polymerase during transcription is to build a molecule of mRNA. RNA polymerase synthesizes RNA using the DNA template strand, creating a complementary mRNA molecule that carries the genetic information from the DNA to the ribosomes for protein synthesis. So, option C is the correct answer. Well done!
The correct answer is indeed C- to build a molecule of mRNA. RNA polymerase is an enzyme that plays a crucial role in the process of transcription. Transcription is the process by which DNA is converted into mRNA, which then carries the genetic information to the site of protein synthesis in the cell.
To get this answer, you need to have a basic understanding of transcription and the role of RNA polymerase. RNA polymerase functions by catalyzing the formation of phosphodiester bonds between ribonucleotides, resulting in the synthesis of an mRNA molecule that is complementary to the DNA template strand. RNA polymerase also helps in unwinding the DNA helix and synthesizing the RNA molecule in the 5' to 3' direction.
By understanding the function of RNA polymerase and the process of transcription, you can determine that building a molecule of mRNA is the correct role of RNA polymerase during transcription.
