What are the similarities and differences with DNA replication and Transcription?

Answer 1

In DNA replication, DNA helicase unzips the helix, DNA polymerase builds the 2 new strands by attaching free nucleotides, and DNA ligase seals the new strands together. When it's done, you get two identical DNA helixes.

In transricption, RNA polymerase attaches to the beginning of the gene (promoter), builds 1 strand of RNA (either messenger, ribosmal, or transfer), and stops at the termination signal. When it's done, you get 1 strand of either mRNA, tRNA, or rRNA.

Answer 2

Both duplicate the original. Transcripts duplicate verbal statements; DNA replications mimic living cells.
