In a point mutation, one single base nucleotide (A, C, T or G) is replaced by a different one. This results in the change of one amino acid in the protein. (A minor change that may or may not affect the overall function of the protein) .a frameshift mutation, one or more base nucleotides are inserted or deleted from the sequence. This shifts the 3 basepair codons resulting in a change in the amino acid sequence that is coded. An entirely different protein (usually nonfunctional) is coded.
Answer:
The two environmental factors are temperature and pH and with that, denaturation occurs. In other words, temperature and pH would affect the protein structure, which it would change their shape and possibly it won't perform its normal function.
Explanation:
There are a lot of human activities that gives negative effects on the earth's ecosystem but I will mention only four: Burning of things such as garbages or plants and trees, dumping of garbages anywhere, chemical substance that are being made and produced, cutting down of trees for replacement of buildings and homes. The human activities increase the occurrence of species extinction by doing this, it eliminates and destroy the homes of the species that are supposed to be living on their natural habitat. But instead of them, living peacefully, by doing these activities, their home will be destroyed that can kill them-- which can lead to extinction.
It happens in glycolysis. It gets broken down into two pyruvates and it happens in the cytoplasm.
