If a lot of tryptophan is present, the operon will be repressed.
Under intermediate amounts of tryptophan, the change to stop codons would cause the ribosome to stall and therefore would mimic as if there were no tryptophan present.
If no tryptophan present, the operon would be maximally expressed.
a - True. The ribosome would always be stalled in the leader sequence - so this wouldn't matter. However, the operon would still be transcribed because the repressor would be active (remember Trp operon is controlled both by attenuation and repression). True as long as there's not much tryptophan to activate the repressor!
b- True - With no tryptophan the repressor isn't engaged and the ribosome is stalled in the leader sequence.
c- Matters about how much tryptophan is available. So True if there's lots of tryptophan available.
d- I would choose this one as all of the above could be true depending on the levels of tryptophan.
False it prevents red blood cells from taking up Oxygen not carbon dioxide
Answer:
Mathematics is used in Physical Science to calculate the measurements of objects and their characteristics, as well as to show the relationship between different functions and properties. Arithmetic, algebra and advanced mathematics may be used. ... Higher math is used for complex relationships between properties.
Explanation:
There would be loss of sensory
function
The dorsal root of spinal nerve
is the part of the peripheral nervous system that picks up sensory signals/ information
and transmits the signal through the nerve to the brain. If the root is damaged
or transected, the brain will no longer receive sensory messages from that
nerve, which means that the patient will have loss of sensation in that area.
