1
Q
What are lamellar bodies?
A
Secretory organelles found in the stratum granulosum which store lipids and form a hydrophobic barrier
2
Q
What are the types of bacterial DNA transfer?
A
Transformation
Transduction

3
Q
What is conjugation?
A
Transfer of bacterial DNA via direct cell-cell contact, which takes place between an M and F pilus.
4
Q
What is a plasmid?
A
Extrachromosomal form of DNA which can replicate independently.
5
Q
What is transformation?
A
Gene transfer when bacteria take up DNA from the environment.
6
Q
What is transposition?
A
DNA segments jump and move for gene transfer.
7
Q
What is transduction?
A
Bacterial gene transfer by using virus or a viral vector,
