An onion is made-up of layers, which is separated by a thin skin or membrane. The cells are easily visible under a high power, compound microscope and the preparation of a thin section is straightforward.<span> </span>

<span>The correct procedure for preparing a stained wet mount of onion epidermis are as follows. First, place a piece of thin onion epidermis on a slide. Second, add one drop of water and put one edge of a coverslip in the water drop, and then slowly lower the opposite edge to the water. Third, put one drop of stain at one edge of the coverslip and put a piece of paper towel at the opposite side of the coverslip. Lastly, allow the towel to absorb some water so that the stain will move under the coverslip and view it under a microscope. </span>

explain how a change in the sequence of nucleotide in a strand of DNA might cause a protein to malfunction
Diano4ka-milaya [45]

Answer: Proteins are made using DNA as a template. The DNA is turned into RNA, and the RNA is then turned into DNA. 

A change in these nucleotides could end up making some part of the protein different. A single nucleotide change could be silent (no change in the protein) or could change a single amino acid (amino acids are the building blocks of proteins). If that was an important amino acid, the protein might not function at all! A silent change can occur because the same set of nucleotides sometimes makes the same final amino acid (for example, reading "gcc" "gca" "gcg" or "gct" nucleotides all mean "alanine" amino acid). 

The deletion of a single nucleotide, or the addition of one, can change the entire sequence of amino acids that come after it! Nucleotides are read in sets of three, so this throws off how the DNA is read. If would be like turning "The brown fox jumps over the dog" into "The gbrow nfo xjump sove rth edo g". Completely different! All of the words are thrown off.

I know it is long but I hope it helped
