Question

Which of the following is NOT a product of transcription? A. a new strand of DNA B. rRNA C. tRNA D. mRNA E. none of the ansers are correct; all of the are products of transciription

Answer 1

Transcription produces mRNA, rRNA, and tRNA, but not a new strand of DNA.

Step-by-step explanation:

The correct answer is A. a new strand of DNA. Transcription is the process by which an RNA molecule is synthesized from a DNA template. The RNA molecule produced during transcription is called messenger RNA (mRNA), which carries the genetic information from the DNA to the ribosomes for protein synthesis. rRNA and tRNA are also products of transcription, as they play essential roles in protein synthesis. Therefore, the correct answer is A. a new strand of DNA.

Answer 2

The product of transcription that is NOT made is A. a new strand of DNA. Transcription produces RNA molecules such as mRNA, tRNA, and rRNA from a DNA template, but not new strands of DNA.

Step-by-step explanation:

The product of transcription that is NOT a new strand of DNA is A. a new strand of DNA. During transcription, several types of RNA are synthesized from a DNA template, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). mRNA is a single-stranded transcript that carries the genetic information from DNA to the ribosome, where it is translated into a protein. tRNA is involved in transferring specific amino acids to the growing polypeptide chain during protein synthesis. rRNA is a structural component of ribosomes, which facilitate the assembly of amino acids into proteins. Therefore, B. rRNA, C. tRNA, and D. mRNA are all products of transcription. As for miRNA, although involved in gene regulation post-transcription, it is not directly a product of the transcription of a gene in the same way mRNA, tRNA, and rRNA are.
