Liula [17]

<u>Mucins</u> are water-soluble, complex glycoproteins that are secreted by goblet cells.

Explanation:

Goblet cells, named after their goblet-like shape, are usually found in the epithelium of respiratory and intestinal tracts in the body. Their main function is to produce mucus (primarily made up of mucins), a slippery combination of proteins, water and sugars, that serves three main functions:

  1. The barrier function: By trapping the unwanted/harmful particles that we inhale and preventing them from entering our system.
  2. The protection function: By keeping the hair-like cilia lubricated and moist to remove the harmful particles.
  3. The defence function: Mucus is made up of certain enzymes, antibodies and proteins that act as a defence mechanism for the body.

A unique property of mucins is their capability to form gels - sticky and viscous substances that work both as lubricants as well as defensive chemical barriers in the body.

A frameshift mutation is a dangerous mutation because it
miv72 [106K]

Answer:

"A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three. "Divisible by three" is important because the cell reads a gene in groups of three bases. Each group of three bases corresponds to one of 20 different amino acids used to build a protein. If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly."
