Saturday Genetics Quiz #17: Genetics Timeline (Part 2)
This week’s genetics quiz questions are a continuation of last week’s:
In what year did the following key moments in genetics occur?
1. Sydney Brenner, Francois Jacob, and Matthew Meselson identify the role of Ribonucleic Acid (RNA).
2. Marshall Nirenberg and H. Gobind Khorana lead teams that show how each of 20 amino acids is coded by a sequence of three nucleotide bases (each series of three bases is called a codon).
3. Fred Sanger develops the chain termination method for sequencing DNA.
4. Kary Mullis and others at Cetus Corporation invent a technique for making many copies of a specific DNA sequence: the polymerase chain reaction (PCR).
5. A rough draft of the human genome is completed and published by the Human Genome Project and Celera.
Answers:
1. Sydney Brenner, Francois Jacob, and Matthew Meselson identify the role of Ribonucleic Acid (RNA) in 1961.
2. Marshall Nirenberg and H. Gobind Khorana lead teams that show how each of 20 amino acids is coded by a sequence of three nucleotide bases (each series of three bases is called a codon) in 1966.
3. Fred Sanger develops the chain termination method for sequencing DNA in 1977.
4. Kary Mullis and others at Cetus Corporation invent a technique for making many copies of a specific DNA sequence: the polymerase chain reaction (PCR) in 1980.
5. A rough draft of the human genome is completed and published by the Human Genome Project and Celera in 2000.
Almost seems as if the field of genetics and genomics has developed at lightning speed.

[...] In a couple of interviews I did recently, I mentioned my sixth grade science fair project that was called something like Heredity, Genetics, and You. Back in 1983, the Human Genome Project hadn’t been launched yet and it was the year Kary Mullis invented PCR (according to the Genome News Network, although other sources point to 1980). My elementary school didn’t have much of a science education curriculum let alone labs where we could try to extract DNA or practice RFLP DNA fingerprinting. So I was left to my own devices without even the Internet to help me do research! *GASP* [...]
