Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During transcription, the information on a ____ molecule is rewritten onto a ____ molecule
A
DNA, tRNA
B
DNA, mRNA
C
DNA, rRNA
D
None of the above
Explanation: 

Detailed explanation-1: -In transcription, a DNA sequence is rewritten, or transcribed, into a similar RNA “alphabet.” In eukaryotes, the RNA molecule must undergo processing to become a mature messenger RNA (mRNA). In translation, the sequence of the mRNA is decoded to specify the amino acid sequence of a polypeptide.

Detailed explanation-2: -During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.

Detailed explanation-3: -In transcription, the DNA sequence of a gene is transcribed (copied out) to make an RNA molecule.

Detailed explanation-4: -Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis.

Detailed explanation-5: -during transcription, the information on a DNA molecule is “rewritten” into an mRNA molecule. when a tRNA anticodon binds to an mRNA codon, the amino acid detaches from the tRNA molecule and attaches to the end of a growing protein chain.
