A point mutation is a mutation that affects only a single nucleotide of a nucleic acid. They involve substitution of one base for another which changes the complementary base as well in DNA, they may also involve insertions and deletions of a single base pair. I therefore think the point mutations in a DNA sequence may profoundly have an effect on the synthesis of proteins, or may also have no effect on protein synthesis at all. These mutations can be beneficial to an organism, however they are more commonly neutral or harmful.

Answer:
Bacteria
Explanation:
Bacteria are a group of single celled organisms that are neither plants or animals.
Bacteria lack cell organelles such as the nucleus and the chlorophyll.
They can be found in many environments and most of them are adapted to survive in extreme environments such as hot-springs where the temperatures are extremely high.
Unlike the plant cell wall, bacterial cell wall has a layer of peptidoglucan which determines their shape. Their cytoplasm contains both DNA and RNA.
