Certain events of DNA replication and transcription are listed below. Identify the combination that is incorrect.
| No. | Event | Transcription | DNA Replication |
| Adenine pairs with thymine | No | Yes | |
| Both DNA polynucleotide chains act as templates | No | Yes | |
| Uracil pairs with adenine | Yes | No | |
| The original DNA molecule is changed after the process | Yes | No |
Options:
Answer:
D
Solution:
During DNA replication, the molecule is copied where both the strands are involved directly. Adenine pairs with thymine and the process is semi-conservative. The original strand is kept intact. During the transcription process, mRNA is synthesized from the template strand of DNA where uracil binds to adenine. Also, the template strand (original strand) is kept intact without any changes.
