What evolutionary advantage does a eukaryotic cell have compared with a prokaryotic cell?
Luden [163]

Answer:

Prokayotes may be defined as the organisms that lacks the nucleus and the membrane bound cell organelle. Eukaryotes have the well defined nucleus and contains the membrane bound cell organelle.

The evolutionary advantage that has been noticed in the eukaryotic cells is the compartmentalization of the cell. The cell compartmentalization separates the cell organelle into the specialized functions. This division of labor increases the efficiency of the cell and regulates the evolution of the complex multi cellular organism.

Maru [420]

Answer:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA

Explanation:

From the amino acid chart, the start codon is represented by the codon AUG which also code for the amino acid methionine. There are three stop codons including UAA, UAG, and UGA. The stop codons signal the end of the translation process of the mRNA. Every other codon within the mRNA chain codes for different amino acids except methionine.

Hence, using the attached amino acid chart:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA
