How is protein synthesis different in prokaryotes and eukaryotes?
Viktor [21]

Answer:

The correct answer is option B

Explanation:

Translation is the process of synthesis of proteins from mRNA in organisms  and transcription is the process of synthesis of mRNA from DNA.

Both prokaryote and eukaryotes shows the presence of translation but both shows many differences in the process of protein synthesis like site of transcription and translation as in eukaryotes transcription takes place in nucleus while translation takes place in cytoplasm. Since prokaryote lacks the nucleus, both transcription and translation takes place in cytoplasm and lacks the process related to post-translational modifications due to which they take place at the same time.

Thus, option B  is the correct answer.

umka21 [38]

Answer:

This process can be performed using immunofluorescence analysis via antibodies.

Explanation:

<u>To test for the hypothesis</u>

To test for the hypothesis we have to  analyze whether the neuronal phenotype is due to the binding of laminin to integrins, and this will enable us to determine which integrins are abundantly expressed on the neuronal cell membrane. This process can be performed using immunofluorescence analysis via antibodies

Finally when no differentiation markers are expressed in the laminin coated plates with mutant cells we can now say that it expresses  integrins
