Answer: A plant cell has a cell wall, a central vacuole, and phosphids or chloroplasts. The cell wall provides structural support and protection.
Answer:
The most likely explanation for the truncated polypeptide -due to the substitution of cytosine for adenine- is that mutation introduced a stop codon in the middle of the gene.
Explanation:
A codon consists of three nucleotides -in the RNA chain- whose order determines a specific amino acid. Not all codons code for amino acids, as there are termination codons, also called stop codons, which are UAG, UGA and UAA.
If in Manny's computer model, the substitution of cytosine by adenine produced a termination codon, the synthesis of a peptide is stopped prematurely resulting in a truncated peptide.

Answer:
preventing viruses from replicating
Explanation:
The nucleus is the 'brain' of a eukaryotic cell and controls all the activities of the cell. It contains most of the genetic information of the cell, in the form of DNA molecules, and is enclosed within a membrane, the nuclear membrane.
