Question

(03.05 MC) In which of the following ways is DNA replication different from DNA transcription? (2 points) New cells can only be created after transcription has taken place. Replication results in mRNA strands while transcription creates new DNA. Transcription happens outside the nucleus and replication happens inside the nucleus. Thymine is used in replication while uracil is used in transcription.

Answer 1

Thymine is used in replication while uracil is used in transcription.

Step-by-step explanation:

Answer 2

The correct option is D.
Transcription is the process by which the information in a DNA molecule is copied into an mRNA strand. Replication is the process by which two new strands of DNA are formed from a single parent DNA. Both the DNA and the RNA are composed of four different bases, three of the bases are the same while one is different for the DNA and RNA. It is only the RNA that has uracil while it is only the DNA that has thymine. Thus, Uracil is involved during the process of transcription since it is an mRNA strand that is formed while thymine is the one involved during the process of replication since it is a DNA molecule that is formed.
