The chaparral biome is generally characterized by its terrain.<br><br><br> True or False?
Igoryamba
I believe this would be false. Chaparral biomes can have many different types of terrains. The land in a chaparral biome can be mountainous, rocky, or flat. Chaparral biomes are generally defined by their temperature and climate. They are very hot and dry, and have mild winters and extreme summers. Hope this helps.

which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?
KATRIN_1 [288]

An example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation is option B: replacement of a polar amino acid with another polar amino acid at the protein's surface.

A frequent and well-known example of a missense mutation is the blood condition sickle-cell anemia. Missense mutations exist in the DNA at a single location in sickle-cell anemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein. Similarly, replacement of a polar amino acid by another polar Ami no acid at the protein's surface is a missense mutation causing change in a single site.

A neutral mutation is one whose fixation is unrelated to natural selection. Therefore, the independence of a mutation's fixation from natural selection can be used to define the selective neutrality of a mutation.
