DNA and Genetics Quiz
1. According to information from the Human Genome Project, how many base pairs of DNA are contained in the human genome?
2. Our genes are the segments of DNA that code for the production of a protein or part of a protein. Not all of the DNA in our cells is actually a part of a gene. How many genes are in the human genome?
3. If all the DNA in the cells of a human were laid end to end, it would form a molecular ladder stretching for 100 billion kilometers ( the equivalent of going to the sun & back over 300 times). What is the length of the DNA molecule in an average human cell?
4. This monk was responsible for establishing the principle that traits can be passed from parent to offspring as discrete units of inheritance.
5. In 1869, this German chemist was the first person to isolate DNA ( He used the pus cells obtained from postoperative bandages - YUCK!)
6. In 1909, this scientist coined the term "gene" to describe these units of inheritance.
7. This scientist was the first to describe genes that could jump around on chromosomes.
a. What is her name? b. What is the scientific name for "jumping genes"?
8. In 1962, these three scientists received the Nobel Prize for describing the molecular structure of DNA. Name them.
9. Although this researcher didn't receive the Nobel prize, it was her famous X-ray crystallography photograph that really showed that the DNA molecule is a double helix.
10. The information in our DNA is responsible for producing our physical traits and making each of us unique. These complex instructions are coded in a language that only has a 4 letter alphabet. What are the four bases found in DNA ?
11. Our DNA is the master blueprint, but the bases in DNA get copied into this nucleic acid before they are used to build proteins.
12. In the 1960's the genetic code was finally cracked, and we understood how the same 4 bases could be used to produce the same proteins in organisms as diverse as a human or a bacterium. Who is the scientist generally credited with cracking the genetic code?
13. Our DNA is folded up into linear threadlike structures called chromosomes. Humans have 46 chromosomes. How many chromosomes are found in the following types of dogs?
a. a Great Dane b. a toy poodle
14. In 1976, the first U.S. genetic engineering company was founded. What was it?
15. This company genetically engineered the first human protein to be produced by a bacteriaum. The bacterium was E.coli. What was the protein?
16. In 1994, the FDA approved the sale of the first genetically modified food. What was it?
17. The human genome project has been officially declared as completed in 2003. In what year was the human genome project first launched?
18. In 1999 the first human chromosome was completely sequenced. Which chromosome ( which number) was it?
