Molecular DNA Outline Pre-test

Determining that DNA is the genetic material, ______ showed that something in virulent bacteria could be transferred to nonvirulent bacteria, making them virulent, as well.

• Griffith

• Avery

• Hershey and Chase

• Chargaff

• James Watson and Francis Crick

______ showed that the "something" Griffith found in his research was DNA and not protein.

• Griffith

• Avery

• Hershey and Chase

• Chargaff

• James Watson and Francis Crick

______, demonstrated that viruses insert DNA into bacterial cells so the cells will make copies of the viruses.

• Griffith

• Avery

• Hershey and Chase

• Chargaff

______ showed that, within the DNA of any given species, the concentration of adenine is always the same as the concentration of thymine, and that the concentration of guanine is always the same as the concentration of cytosine.

• Griffith

• Avery

• Hershey and Chase

• Chargaff

• James Watson and Francis Crick

______ building on the prior X-ray research of Rosalind Franklin and others, discovered that DNA has a double helix shape, consisting of two polynucleotide chains held together by bonds between complementary bases. Along with Chargaff's rules, this led to a better understanding of DNA's structure and function.

• Griffith

• Avery

• Hershey and Chase

• Chargaff

• James Watson and Francis Crick

You should be able to explain the central dogma of molecular biology: DNA to RNA to proteins. The central dogma of molecular biology states that ______.

• RNA contains information to make ribose

• DNA contains instructions for making a protein, which are copied by RNA

• DNA makes proteins

• nothing

RNA then uses the instructions to make a ______.

What is central dogma?

• DNA → RNA → Protein

• RNA → DNA → Protein

• Protein → DNA → RNA

• DNA → Protein → RNA

What is DNA?

• deoxyribonucleic acid

• ribonucleic acid

• the genetic material in your cells

• an enzyme that makes proteins

What direction does the lagging strand go to?

• 3' to 5'

• 5' to 3'

• 8' to 6'

• 7' to 4'
