A mutation that causes production of a defective pilus in a bacterium will prevent __________.
daser333 [38]

Answer:

The correct answer is: Attachment.

Explanation:

  • Pilus are thread like structures which are present on the surface of the bacterial cell.
  • They are mainly responsible for attaching the bacterial cells to a substrate, for obtaining food or to an eukaryotic cell for the purpose of infection.
  • Pilus also mediate the process of conjugation in some bacterial cells.
  • Conjugation is a process by which genetic material or plasmids are transferred from one bacteria to another through a channel formed in between the two bacteria by the help of the pilus.
  • Pilus also helps the bacteria by preventing them from getting recognised by the immune cells in the host.
  • A defective pilus will affect all the above processes, resulting in death of the bacteria.

What can you learn about a sample from an sds-page analysis?
puteri [66]

Option <u>(c.) the purity of the protein</u>, will be the right one.

Sodium Dodecyl Sulphate provides a negative charge to each protein as a function of their molecular size. It is an anionic detergent, as well as it is there to determine the relative abundance of major proteins.

After denaturing, proteins get unfolded and gets coated with SDS detergent molecules. The SDS-PAGE technique is used for the separation of protein based on their molecular size/weight/mass.

It is so because as it identifies the proteins by its molecular weight. Therefore, SDS is used in denaturing polyacrylamide gel electrophoresis for the determination of protein molecular weight, the SDS-PAGE is a technique.
