Question: A student makes a claim that a cell is undergoing the process of transcription. What evidence would be present to support this claim?
A) tRNA with anticondos is carrying amino acids to the ribosomes.
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.
C) Ribosomes are reading mRNA molecules three nucleotide at a time to synthesis proteins
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Answer:
The evidence that the student have to produce as an evidence is the "RNA polymerase using the single strand of the DNA molecule as a template for mRNA production."
Explanation:
We know, that in transcription the genetic information from the DNA is copied into RNA for production of the proteins. According to various research methods, to know whether the cell is going through the transcription, a student can use the bacteriophage coat protein, which must have labelled with the fluorescent protein for studying it under microscope. After, this has been done, in the right location stem loop present, the RNA will be seen initiating of the elongation step, hence the transcription site will be more visible when the coat protein binds to the new RNA, which has happened in the transcription site. We can know see the transcription as fluorescent which will help the student to determine the process of transcription in the cell. Presence of promoters are important to demonstrate the process.
