Function

Question 1

What are the function of cell extensions?

Answer 1

Flagella: propulsion and movement
Fimbriae: adhere to host cells (factor in virulence)
Pili: attach to other bacteria for transference of genetic material

Question 2

What is the function of DNA?

Answer 2

hold genetic material “blueprint” or “recipe” needed to create the structures for support and activity.

Question 3

What is transcription?

Answer 3

It is taking the information stored in DNA and transposing it onto another strand: RNA ultimately to make polypeptides the “structures” for support and activity.

Question 4

What is translation?

Answer 4

It is the process of converting the information obtained from RNA into the necessary ‘string’ of amino acids for cellular function and support.

Question 5

What does a ribosome do?

Answer 5

It aids in the development of the polypeptide chain during translation of the mRNA.

Question 6

What are the functions of glycocalyces?

Answer 6

Capsules protect the bacteria, in a gelatinous fluid, from being engulfed by eukaryotic cells and contains water to prevent desiccation.
Slime layers prevent desiccation by coating the bacteria in a diffuse material.

Question 7

What is the function of a plasma membrane?

Answer 7

To regulate the movement of things passing to and from the intracellular/extracellular spaces.
