1. A measure of yeast cells preparing for mating is:
a. |
The percentage of unbudded cells |
|
b. |
The percentage of schmooing cells |
|
c. |
The number of budding cells |
2. The alpha mating factor pathway signals through a:
a. |
Kinase receptor |
|
b. |
Ion channel |
|
c. |
G protein |
|
d. |
Nuclear receptor |
3. A malignant tumor is more dangerous than a benign tumor because ______________________.
a. |
Its cells are proliferating faster. |
|
b. |
It causes neighboring cells to mutate. |
|
c. |
Its cells invade other tissues. |
Ans -1 ) The correct answer for this question is -
b) the percentage of schmooing cell
Explanation -
The percentage of schmooing is the measure of preapring of yeast .
A cell release pheromen which reponse by alpha cell and growing a projection for mating . This is called schooming . And their presence reflect preapare for mating .
Answer 2) The correct answer for this question is -
C) G protein
Explanation - GPCR ( G protein coupled receptor ) contain G protein and it is responsible for secondry messanger and this messanger do further process.
Alpha mating factor behave as dignal and activate GPCR for their process .
Ans 3) The correct answer for thid question is -
A) Its cells are proliferating faster .
Explanation -
Malignent cancer is refered as more dangerous then Benign. Malignent cells proliferate with fast rate and hence it grow too fast as well as show metastasis .
Due to this reason melignent cancer is too dangerous while benign show static like not spreading like malignent hence it is not hsrmful like malignent.
