Explain (in one or two lines) the function of the followings: (a) Promoter (b) tRNA (c) Exons
a) Promoter Promoter is a location of DNA that allows in starting up the method of transcription. It serves because the binding web website online for RNA polymerase. (b) tRNA tRNA or switch RNA is a small RNA that reads the genetic code gift on mRNA. It contains precise amino acid to mRNA on ribosome at some stage in translation of proteins. (c) Exons Exons are coding sequences of DNA in eukaryotes that transcribe for proteins.
