template strand - CORRECT ANSWER✔✔the strand of DNA that specifies the complementary
mRNA molecule
coding strand - CORRECT ANSWER✔✔the strand of DNA that is not used for transcription and is

independent events - CORRECT ANSWER✔✔The outcome of one event does not affect the
outcome of the second event
multiplicative rule of probability - CORRECT ANSWER✔✔If two events are independent, then
the probability that they both occur is given by p(A,B)=P(A)P(B)
Conditional Probability - CORRECT ANSWER✔✔the probability that one event happens given
that another event is already known to have happened
conditional probability equation - CORRECT ANSWER✔✔P(A/B) = P(AnB)/P(B)
Binomial Distribution equation - CORRECT ANSWER✔✔P(x) = {(n!)/((n-x)!(x!))} ( p^x)(q^n-x)
