If a strand of DNA was ATCGTACGTA. What would the
complimentary RNA strand be?

UAGCAUGCAU

Explanation:

In an RNA strand, Thymine is present as Uracil meaning Thymine unable to be present in an RNA strand.

Guanine (G) and Cytosine (C) are base-pairs, and will not pair up with Adenine of Thymine/Uracil

Adenine (A) and Thymine (T) are base-pairs, and will not pair up with Cytosine or Guanine.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

b - the respond is innate and varies over time.

good luck!
