If an mRNA molecule contains 30 nucleotides that will be translated, this molecule would code for
amino acids.
A) 30
B) 10
C) 90
D) 3

3

Explanation:

The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid.

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."
