Transcription Process

Transcription is the process by which genetic information in DNA is copied into a complementary RNA sequence. It occurs in the nucleus of eukaryotic cells and involves the enzyme RNA polymerase. The coding strand of DNA serves as a template for the synthesis of the RNA molecule.

Rules for Transcription

During transcription, certain rules are followed to generate the corresponding mRNA sequence:

1. The mRNA sequence is complementary to the coding strand of DNA.
2. Adenine (A) in DNA is replaced by uracil (U) in mRNA.
3. Thymine (T) in DNA is replaced by adenine (A) in mRNA.
4. Guanine (G) in DNA is replaced by cytosine (C) in mRNA.
5. Cytosine (C) in DNA is replaced by guanine (G) in mRNA.

Transcription of AGGTATCGCAT

To determine the corresponding mRNA sequence for the given coding strand "AGGTATCGCAT," we need to apply the rules mentioned above:

1. The DNA sequence is "AGGTATCGCAT."
2. Replacing adenine (A) with uracil (U) gives "UGGUAUCGCAU."
3. Replacing thymine (T) with adenine (A) gives "UGGUAUCGCAU."
4. Replacing cytosine (C) with guanine (G) gives "UGGUAUCGCAU."
5. Replacing cytosine (C) with guanine (G) gives "UGGUAUCGCAU."

Therefore, the corresponding mRNA sequence for the given coding strand "AGGTATCGCAT" is "UGGUAUCGCAU."

Summary

The transcription process involves the synthesis of a complementary RNA sequence from a coding strand of DNA. The rules for transcription include replacing adenine (A) with uracil (U), thymine (T) with adenine (A), guanine (G) with cytosine (C), and cytosine (C) with guanine (G) in the DNA sequence. Applying these rules to the given coding strand "AGGTATCGCAT" results in the corresponding mRNA sequence "UGGUAUCGCAU."
