Answer 17

there imprtant becuase the rules of base pairing tell us that if we can "read" the sequence of nucleotides on one strand of DNA, we can immediately deduce the complementary sequence on the other strand.

plzzzzzzzzzzzzzz help me omg

Answer 39

theres always room for error in dna analysis data there testimony would gave to reflect that i suppose

Answer 40

You overcome errors in data by quatifying them and factoring them in
