At which checkpoint in the cell cycle would a tumor suppressor gene repair dna function

Biology
1 answer:
sp2606 [1]3 years ago
5 0
During inter-phase of cell division, the genetic material is duplicated to allow for division into 2 identical daughter cells. The tumour suppressor gene checks for errors in the DNA, and if found, apoptosis (cell death) is initiated by p53 protein. The pRb (retinoblastoma) protein stops the progression of the cell cycle form G0 into S phase if the cell division is complete hence stemming unregulated cell division.

Mode of action of aldehydes and Quaternary ammonium compounds is
natulia [17]

Answer:

Aldehydes have antibacterial, antifungal, antiviral and sporicidal activity. These are helpful to destroy the spores of Bacillus subtilis and Clostridium sporogenes. Glutaraldehyde and formaldehyde are commonly used aldehydes in disinfectants.

Quaternary ammonium compounds work by denaturing the proteins of the bacterial or fungal cell, affecting the metabolic reactions of the cell and causing vital substances to leak out of the cell, causing death.

Which pair is incorrectly matching polymer-monomer? nucleic acids - nucleotides proteins - amino acids lipids - monosaccharides
Andrew [12]

The pair that incorrectly matches polymer-monomer is lipids-monosaccharides (option C).

<h3>What is a monomer?</h3>

A monomer is a small molecule which can be covalently bonded to other monomers to form a polymer.

A polymer, on the other hand, is a large molecule made up of a chain of many monomeric units, formed by chemically bonding together.

The following are the monomer-polymer combination we have in nature;

  • Carbohydrates - simple sugar/monosaccharide
  • Protein - amino acid
  • Lipids - fatty acid
  • Nucleic acid - nucleotide

Therefore, the pair that incorrectly matches polymer-monomer is lipids-monosaccharides.
