Final answer:
Transcription is similar to DNA replication but has several key differences. Both processes involve the synthesis of a complementary strand, but transcription only uses one strand of DNA as a template, does not require a primer, and involves uracil (U) pairing with adenine (A) instead of thymine (T).
Step-by-step explanation:
Transcription is similar to DNA replication in that it involves the synthesis of a complementary strand. However, there are several key differences between the two processes. In transcription, only one strand of DNA is used as a template, while in DNA replication, both strands are used.
Additionally, transcription does not require a primer, unlike DNA replication. Another difference is that in transcription, uracil (U) pairs with adenine (A) in the DNA template, whereas in DNA replication, thymine (T) pairs with adenine (A).
