Compare and contrast transcription termination in bacteria and eukaryotes. a) What sites signal the transcription complex to ter

minate in prokaryotes and to terminate/polyadenylate in eukaryotes
Biology
1 answer:
Anestetic [448]3 years ago
5 0

Answer:

Prokaryotes have RHO dependent and RHO independent transcription termination; Eukaryotes have the poly A signal and downstream termination sequence transcription termination.

Explanation:

Transcription is the process by which mRNA is synthesized from DNA by the enzyme RNA polymerase. The process of transcription is keep going until some termination signal/mechanism stops it. There are various differences of transcription in prokaryotes and eukaryotes like types of RNA polymerases, nitrogenous bases utilized and the mechanism of transcription termination.

Prokaryotic termination may be dependent on RHO proteins or not.

  • In RHO dependent pathway the RHO factor (protein) slide towards the RNA polymerase along the DNA and dissociate it from DNA.
  • In RHO independent pathway a stem loop is formed by mRNA from a sequence which pasues the polymerase temporarily and consequently causes dissociation of RNA polymerase with help of poly-uracil sequence.

Eukaryotic termination may occur through poly A signal and downstream termination sequence;

  • Poly A tail is added  mRNA for its protection. It prevent the mRNA degradation.
  • The polymerases pauses on the termination signal and ultimately dissociates from DNA.

DESCRIBE what activation energy is.
Semmy [17]
Activation energy is the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.

for example , striking a match on the side of a matchbox provides the activation energy, in the form of heat produced by friction.

How does rough ER from smooth ER?
irinina [24]

Answer:

Rough endoplasmic reticulum differ from smooth endoplasmic reticulum by the presence and absence of ribosomes in their surface.

Explanation:

Rough endoplasmic is named so because RER contain ribosomes at their surface and due to the presence of ribosomes rough endoplasmic reticulum play an importnt role in protein synthesis or translation.

 Whereas smooth endoplasmic reticulum does not contain any ribosome in its surface.smooth endoplasmic reticulum helps in the biosynthesis of lipid and steroids along with detoxification of toxic compounds.
