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.
Eucariotec like red blood cells and others
Procariote is like bacteria or amiba
You can use a chromosomal karyotype to see if there are any abnormalities with the normal 23 pairs of chromosomes that every healthy human has. Different abnormalities like an extra chromosome (trisomy), missing a chromosome (Minos omg), or having certain parts missing or added on can lead to a person to be diagnosed with certain disease (ex: Down syndrome is an extra chromosome on the 21st chromosome).
