PLEASE PLEASE PLEASE HELP GIVING Changes in result in a change in protein structure which alters the -type of the organism and MIGHT increase .

DNA, genotype and resistance.

Explanation:

Change in DNA of an organism results in a change in the shape and structure of protein because DNA has the codes of instructions on the basis of which ribosomes synthesis proteins for the cell. This change occurs due to mutation in the DNA sequence that causes change in protein. Due to this mutation, the genotype of an organism changes and might increases its resistance that leads to its survival in that environment so we can say that mutation has good effects on the organisms.
