Cells can repair themselves in a molecular level through its DNA and the process involve, either the old damage cells are renewed and resynthesized by new ones as cell divides and undergoes such division.
<span><span>Organelles
are tiny parts of a cell, in analogy are like organs. They perform
various tasks vital for a cell to survive. They deliver information,
send nutrients and excrete waste and protect cells from antibodies and
other microorganisms that could and possible harm the cell itself.<span> </span></span>
Cells repair themselves through the process of cell division and mitotic process. <span>Mitosis
occurs more in your body since it changes, modifies and requires cell
division at maximum rate in many useful situations with the stand to a
particular system and organ. Mitosis and meiosis are simply cell
division processes that occurs differently, they're characteristically
divergent from each other according to their function and structure.<span>

Answer: 2).it will result in an incomplete protein that does not function properly
Explanation: Mutations are permanent changes in the nucleotide sequence of a DNA. A mutated DNA sequence will give rise to an mRNA molecule with an altered nucleotide sequence and consequently lead to the synthesis of a nonfunctional protein with an altered amino acid sequence.
Amino acids are coded for by three nucleotide sequences called codons. There are 64 universal codons, 61 of them code for amino acids while 3 of them do not code for any amino acid and are called stop codons. Translation occurs when the ribosome encounters a stop codon in an mRNA.
When UAC codon is replaced by UAA codon in an mRNA sequence, protein synthesis will stop because UAC codes for tyrosine while UAA is a stop codon that do not code for an amino acid. This will result in an incomplete nonfunctional protein.
The common denominator is 8, hope this helps.
