![]() ![]() Mutations can provide resistance to antibiotics If a mutation gives the bacterium an advantage in a particular environment, this bacterium will grow better than its neighbors and can increase in numbers – it is selected for. Here, Darwin’s theory of natural selection comes in. While some mutations are harmful to the bacteria, others can provide an advantage given the right circumstances. Mutations can also form due to external factors like radiation or harmful chemicals. These mutations are random and can be located anywhere in the DNA. Every time the bacterium goes through this process there is a chance (or risk, depending on the end result) that errors occur so-called mutations. Before the bacterium can divide, it needs to make two identical copies of the DNA in its chromosome one for each cell. When bacteria multiply, one cell divides into two cells. ![]() Mutationsīacteria grow and multiply fast and can reach large numbers. Resistant bacteria survive antibiotic treatment and can increase in numbers by natural selection. The structure then changes its function.Mutations can result in antibiotic resistance in bacteria. Which inturn changes the protons structure. 5 0 0 I 4 0 The mutations change the gene sequence, Because each of the 317 amno acids have an mRNA that goes with them, which was a DNA triplet with a 3 base sequence. protein structure and function is then determined by the ammo acid sequence. The DNA sequence gives us the code for the amino acid sequence. Hypothesis to explain how the changes in the MC1R protein’s amino acid sequence might affect its function. Using the information in the introduction on mutations and your knowledge of proteins, develop a ** Mice with the wild-type (nonmutant) Mc1r gene have light-colored fur.
