emmainna [20.7K]

<u>Answer:</u>

<em>Reduction of sulfur compounds and the release of hydrogen sulfide is happening here.</em>

<u>Explanation:</u>

Sulfur is an important element in the sulfur cycle. Sulfur compounds can be found on earth in various forms. They can be found in mineral rocks and organic matter. It is the <em>work of bacteria to reduce sulfur</em> compounds and convert them to sulfides.

There are different types of bacteria that reduce various sulfur containing compounds. They are <em>sulfate-reducing bacteria, sulfur-reducing bacteria, sulfite reducing bacteria etc.</em>  In a swamp there is  low oxygen availability and organic matter decays in this condition.

<em>The sulfate reducing bacteria oxidizes the organic matter  and releases Hydrogen sulfide.</em>

Analyze how a point mutation can affect the overall protein shape and function, using hemoglobin as an example.
aniked [119]

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.
