Answer:

<u>3) Uncontrolled cell division occurred as a result of gene mutations</u>

<u />

Explanation:

Spontaneous modifications within the genome may occur during the process of cell division. When copies of the DNA inside the cell are made, these mutations cause errors; and can include small single nucleotide polymorphisms, and large scale additions or deletions across multiple genes.

Some, like somatic mutations, exist only inside vegetative (body) cells, that cannot be passed onto offspring. This is caused by several factors like

  • UV radiation,
  • chemical mutagens,
  • infective agents

UV radiation damages strands of DNA, by causing dimers to form; here, consecutive nucleotide bases covalently bond instead of those on the complementary strand. This conformational change causes errors in DNA proofreading and repair mechanisms where bases are not well-incorporated into the strand- tumors (clumps of uncontrolled cell growth) may form, resulting in melanoma, a type of skin cancer.

What is the reaction needed to remove a glucose molecule from a polysaccharide, 100 glucose molecues long
vaieri [72.5K]

The reaction needed to remove glucose molecule from a polysaccharide is hydrolysis.

Glucose is a type of monosaccharide which is used in the body for energy.

These monosaccharides such as:

  • Glucose,
  • Fructose and
  • Galactose;

can combine together to form a larger molecule of sugar known as polysaccharides in a reaction called condensation reaction.

Examples of polysaccharides are

  • Chitin
  • Cellulose
  • Start
  • Inulin

These polysaccharides can also be broken down to form the various monosaccharides that makes them up.

The hydrolysis of polysaccharides involves the breaking of the glycosidic bonds that hold the monomers of a polysaccharide molecule together.

This leads to the formation of monosaccharides such as glucose.
