1. The term promoter is used to describe all the sequences that are important in the initiation of transcription of a gene.
- In prokaryotes, the promoter is recognized by RNA polymerase and an associated sigma factor, which in turn are often brought to the promoter DNA by an activator protein's binding to its own DNA binding site nearby.
- In eukaryotes, the process is more complicated, and at least seven different factors are necessary for the binding of an RNA polymerase-II to the promoter.
Terminator in transcription: A section of genetic sequence that marks the end of transcription.
2.
| Introns | Exons |
| Non coding region | Coding region |
| Termed as nucleotide sequences seen within the genes which are removed through RNA splicing for generating a mature RNA molecule | Termed as a nucleic acid sequence which is represented in the RNA molecule. |
| Less conserved which means that their sequence changes very frequently over time. | Very much conserved. |
| Not at all implicated with the protein coding. | Codes of proteins |
| DNA bases that are found in between exons. | DNA bases which are translated into mRNA |
