Q

Genetic cause disease
other than T1 diabetes

A

Sickle cell anemia
Mutation change struct chromosome 11 HbA gene

variant haemoglobin
- less soluble plasma
- nvr bind readily, oxygen

T2 diabetes is genetic predeposition

Q

Bacteria Cell vs Virus Particle
defintion + require host? + reproduction

A

Definition?
bacteria
free living cell
virus
intracellular parasite

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Req host?
bacteria
No.
virus
must b Living host cell

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Reproduction via whose ribosomes, enzymes?
bacteria
my own

virus
living host cell

cell is the point. cos they need ribosomes/enzymes to reproduce

influenza vs pneumoccocal disease

similar methods prevent transmission

A

Preventative, not treatment method
- vaccinated
- wear mask, isolate when unwell
- handwashing -> soap, water
