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

Design an experiment to determine whether lactase persistence in the different global hot spots was caused by one or several mut
valkas [14]

Answer:

Collect DNA from individuals who are lactase persistent and are from the global hot spot populations. Then look for genetic differences correlated with lactase persistence; the first place to look would be in and around the lactase gene. Compare the genetic differences to see if they are the same or different.
