lesson 6 Flashcards
_______ move throughout the cell and arrive at their destination under the direction of ____ _____
proteins, signal sequences
____ _____ consist of amino acids and may or may not be ____ from the protein once it has arrived at its target destination
signal sequences, cleaved
t or f) signal sequences are patterns
false
t or f) Signal sequences have groups or properties that help direct the movement of proteins
true
a signal sequence may be necessary for protein ____
- X is necessary for Y
- No X = ________
- X does not _______ Y
localization, no Y, guarantee
t or f) if X is necessary for Y, it does not necessarily guarantee it. There may still be other things present
true
if we say that X is a sufficient condition for Y this means that if we have X then _____ __ ____ aka the presence of X _______ Y will occur
Y will happen, guarantees
having gasoline in my car is (necessary / sufficient) to start my car
sufficient
rain pouring from the sky is (necessary / sufficient) for the ground to be wet
necessary
to test if X is necessary for Y we need to do what type of experiment? if we take out X and we don’t get Y then we know that X is necessary but does not tell us if it is…
lose it, sufficient
to say that X is sufficient for Y we need to do a ____ __ experiment. An example of this were the eyeless experiments
move it
a ___ ____ can be both necessary and sufficient for protein localization
signal sequence
hypothetically, if a certain signal sequence is ______ but NOT ______ for protein localization this would mean that we may need multiple signal sequences to get it where it needs to go, or we need something else to be active.
necessary, sufficient
Experimenters believed that myoD was a master regulator for muscle development. If we think tis involved in muscle proteins we need to know if its there thus we do a ___ ___ experiment. If we wanted to look for protein we could do a ___ ___ or western blot, if we wanted to look for mRNA and localizing it we could do _____
find it, reporter gene, ISH
