Answer:

A point mutation can be described as a mutation in which changes occur in a single nucleotide. A nucleotide may get changed, deleted or inserted from the sequence of DNA. Point mutations can be harmless or harmful depending on the nucleotide in which the changes occur.

A change in just one nucleotide can result in the formation of wrong amino acid and hence changed or wrong proteins can be formed. If the original protein was involved in cellular reproduction, then the entire process of reproduction can be affected by a point mutation.

Sickle- cell anaemia is a disease in which the body fails to produce enough healthy red blood cells. This disease occurs due to point mutation. Point mutation occurs where glutamine (GAG) of the β-globin gets changed into valine (GUG). This change causes the haemoglobin to get a deformed structure due to which it is not able to carry out oxygen.

How can a single cell bacterium grow and reproduce exponentially
irinina [24]
Bacteria reproduce exponentially, and at a brisk pace, meaning one bacterium becomes two, two become four, four become eight, and so on. Because of this, bacteria populations can double in four to twenty minutes, giving bacteria the ability to form millions of cells in as little as a few hours. Under the right conditions, a single bacterial cell can replicate into as many as one billion individual bacteria in just 10 hours.

The risk of schizophrenia among biological relatives is greatest for identical twins.
Kobotan [32]

The risk of schizophrenia among biological relatives is greatest for identical twins. This is a true statement.

<h3>What is schizophrenia?</h3>

Schizophrenia is a neurological disorder that causes an affected individual to lose touch of reality.

Schizophrenia can be caused by the following:

  • Genetics: Gene defects caused by mutation such as deletions or duplications of genetic material increases risk of schizophrenia.

  • Environment: Urbanicity, migration, cannabis, childhood traumas, infectious agents, obstetrical complications and psychosocial factors

  • Brain chemistry and circuit

  • Brain abnormalities: Impaired communication between brain regions leads to the associated symptoms and cognitive changes.

According to research, the risk of schizophrenia among biological relatives is greatest for identical twins because they are genetically identical.
