The best  answer is A.

In most living  organisms, codons are assigned to the same amino acids.

Each amino acid is coded for by a set of three nucleotides in DNA. Each set of nucleotides is called a codon or triplet. The set of all possible three-nucleotide combinations is called the genetic code or triplet code. It is universal. 

These combinations are 64 in number. Of these, 3 do not code for any amino acid and are called non-sense codons, which leaves 61 which code for specific amino acids and are called sense codons.

A cellular structure that can be found in each type of cell that is unique to each type of cell, but that has a similar function
34kurt

Answer

Complex barrier to the flow of substances out of the cells,and restrictions to inflow of unwanted substances into the cells. The hydrophobic and hydrophilic nature of the cell membrane controls the entry of substances from the extracellular medium into the intracellualr. In addition the polarity restricts certain substance movement across the walls.

Serve as the selective channels  for the  influx of certain substances into the cells, and the out flux of wastes.This is through ion channels for the movements of ions across.

Provide insulation to the cells,to maintain the constant internal temperature,this is through the presence of lipids as( Phospholipids and cholesterol).The latter prevent the clogging of the lipids in the cell membrane therefore preventing frozen up of the cell membrane,providing insulation.

Separation of metabolic process in the cell.

Explanation:

Cell membrane-This is present in all cells.But the variation of its constituents makes it unique to each cell. Although it performs the same role, the location and role the cells it bounded, reflects its  constituents, it is made up of lipids, carbohydrate, protein and cholesterol
