Question

Describe the functions of the regions of a complete eukaryotic gene.

List the parts of a gene that are transcribed to RNA.

List the regulatory elements in a gene that are not transcribed.

Distinguish between regulatory elements and transcription factors.

List all the molecular components of the transcription initiation complex.

Briefly describe the role of enhancers, activators, and DNA bending proteins in the formation of the transcription initiation complex.

Answer 1

The eukaryotic gene contains two regions- intron and exon. The intron region are excised from the new DNA molecule and the exon region are retained in the matured molecule.

The strand of DNA are transcribed into the RNA.

RNA polymerase and promoters are the components of the transcription initiation complex.

Promoters are the DNA sequence which helps to initiate the process of transcription. Enhancers are the sequences that help in increasing the rate of transcription. DNA bending protein helps in fixing the geometry of the DNA.
