A mutation that involves one or a few nucleotides is called
a) mutagen
b) inversion
c) point mutation
d) translocation
Answer:
c) point mutation
Explanation:
When only one or a few nucleotides of a gene are changed by mutation, this is called a point mutation. A point mutation can add one additional nucleotide to the wild type gene or may delete or substitute a nucleotide from it. For example, if a wild type gene sequence is "ATATATATA", then the addition of "C" at the position 4 will change it into "ATACTATATA". This addition of new nucleotide is called point mutation since only one nucleotide is added to the gene. Point mutations can cause serious genetic disorders such as sickle cell anemia.
When researchers create lesions, they are destroying a piece of the brain.

The column of mercury in the barometer is lowest when the barometer is ion location 4. Atmospheric pressure measured by the barometer decreases with an increase in altitude. Atmospheric pressure is caused by the column of air above the ground level at any given point on the earths surface thus an increase in altitude leads to a decrease in this column leading to a decrease in atmospheric pressure.
