Can someone help me? I need to write an essay for these questions and I need some help:

1)
Descrive the production and processing of mRNA molecule. Discuss how gene expression can be regulated at the transcription level.

2)
Describe the steps of protein synthesis, beginning with the attachment of a messenger RNA molecule to the small subunit of a ribosome and ending with the release of the polypeptide from the ribosome. Also include how different types of RNA functions in this process.

3) Descrive the biochemical composition and structure of replication of DNA. Discuss how recombinant DNA techniques may be used to connect a point mutation.
