Question

DNA encodes the cell's genetic instructions for making proteins. The process of making proteins from DNA is divided into two stages called transcription and translation. Transcription is further divided into three steps called initiation, elongation, and termination. Classify the statements about transcription according to the step in which each occurs.

Initiation Elongation Termination
1. The RNA polymerase binds to the group of transcription factors at the promoter.
2. The DNA double helix unwinds, and RNA synthesis begins.
3. The RNA polymerase traverses the DNA template, adding complementary base pairs in the 5' to 3' directions.
4. The newly transcribed RNA transcript is proofread for errors.
5. The RNA polymerase stops adding base pairs when it reaches a certain DNA sequence that signals the end of the gene.
6. The RNA transcript is released.
7. The RNA polymerase detaches from the DNA.

Answer 1

Step-by-step explanation:

Initiation:

1 The RNA polymerase binds to the group of transcription factors at the promoter.

Elongation:

2. The DNA double helix unwinds, and RNA synthesis begins.

3 The RNA polymerase traverses the DNA template, adding complementary base pairs in the 5' to 3' directions.

4The newly transcribed RNA transcript is proofread for errors.

Termination:

5. The RNA polymerase stops adding base pairs when it reaches a certain DNA sequence that signals the end of the gene.

The RNA transcript is released.

The RNA polymerase detaches from the DNA.

Transcription is the process of making an RNA copy of a gene sequence. This process is divided into three steps: initiation, elongation, and termination.

Initiation is the step where the RNA polymerase binds to the group of transcription factors at the promoter.

Elongation is the step where the RNA polymerase traverses the DNA template, adding complementary base pairs in the 5' to 3' directions.

Termination is the step where the RNA polymerase stops adding base pairs when it reaches a certain DNA sequence that signals the end of the gene, the RNA transcript is released, and the RNA polymerase detaches from the DNA.
