Hello students, here many questions are asked.
00:02
The first question is if there is a mutation which results in loss of function of enzyme 2, how will that affect the production of b and c and whether that mutation will be lethal or not? the right answer is the production of b and c will be affected.
00:29
This is because a will not be converted to b and this mutation can be lethal if b and c are essential for organisms survival.
01:03
Next question is in addition if a is added to the minimal media will the mutation result in lethality and they have asked to explain about adding b or c to the minimal media.
01:21
If a is added to the minimal media the mutation will not be lethal.
01:34
This is because the organism can still produce b and c using the added a.
01:49
If b or c is added to the minimal media then it may rescue the organism if only one of them is essential for survival.
02:08
Third question is if there is a mutation which results in loss of function of enzyme 2, how will that affect the production of b and c and they have asked to verify whether this mutation would be lethal or not.
02:21
If there is mutation that results in loss of function of enzyme 2 then the production of c will be affected.
02:39
This is because b will not be converted to c and this mutation can also be lethal if c is essential for organisms survival.
03:05
Next question is if a is added to minimal media will the mutation in enzyme 2 result in lethality and they have asked to explain about adding b or c in the minimal media.
03:18
If a is added to minimal media then the mutation in enzyme 2 may still result in lethality...
