All of the following are differences in transcription, RNA processing, and translation between prokaryotes and eukaryotes except
Mazyrski [523]

Answer:

the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.

Differences:

- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from  

- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases

- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors

Explanation:

Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:

1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.

2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)

3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.

Which technique involves injecting an animal with a radioactive molecule to see which part of the olfactory bulb is most activat
Rudiy27

The asnswer is 2DG also known as 2-Deoxy-D-glucose.  2DG is a glucose molecule that has the 2-hydroxyl group replaced by hydrogen, so that it cannot undergo further glycolysis. As such; it acts to competitively inhibit the production of glucose-6-phosphate from glucose at the phosphoglucoisomerase level (step 2 of glycolysis).

How does the life cycle of a star compare to that of a human
solong [7]

Short answer:

It has a "birth" (in the nebula) just like humans are born inside their mothers.

It gets older and changes(in color which is due to its Temperature and in Size) just like humans as they go from babies to adults to elders. They also both die (Stars exploded or become black holes) stars "die out" and humans literally die. Both can die(not literally for stars) from old age.
