When summarizing the process of transcription in a cell as a gene is used to build a polypeptide, which of these statements accurately reflects the process of transcription? You may choose all that apply.

This question lacks options, the options are:

A) An mRNA molecule is produced in the nucleus of the cell.

B) The ribosome attaches to the DNA to build a polypeptide

C) The resulting RNA molecule is a complement of the gene on the DNA.

D) The RNA molecules contains three nucleotides in a row whose bases form

a codon.

E) A polypeptide is synthesized based on the sequence of nucleotides on the tRNA molecule.

The answers are A, C and D

Explanation:

Transcription is the first process of gene expression whereby a mRNA is synthesized from a DNA template. Transcription, which occurs in the NUCLEUS, takes place in three stages namely: initiation, elongation and termination.

- Initiation involves the attachment of RNA polymerase to the DNA molecule, inducing the unzipping of the double stranded DNA.

- Elongation involves the synthesis of RNA strand by adding complementary nucleotides based on the ones read on the DNA strand.

- Termination signals the end of the transcription process.

Based on this question and the above explanation of the transcription process, the following pertains to transcription in the nucleus:

- mRNA molecule is produced in the nucleus of the cell.

- The resulting RNA molecule is a complement of the gene on the DNA.

- RNA molecules contains three nucleotides in a row whose bases form a codon.
