DNA structure
This double-helical molecule is composed of nucleotides that include a phosphate, a sugar, and a nitrogenous base.
What is DNA?
DNA replication occurs during this phase of the cell cycle.
What is the S phase?
The primary function of DNA is to store and transmit this.
What is genetic information?
This scientist’s experiment with mice and pneumonia-causing bacteria led to the discovery of transformation.
Who is Frederick Griffith?
In eukaryotic cells, DNA is found in this organelle.
What is the nucleus?
These bases pair specifically through hydrogen bonds.
Thymine and Adenine/ Cytosine and Guanine
This enzyme is responsible for unzipping the DNA double helix.
What is helicase?
DNA provides the instructions to make these essential biological molecules.
What are proteins?
This scientist used radioactive isotopes to confirm that DNA, not protein, is the genetic material.
Who are Hershey and Chase?
This term describes a change in the DNA sequence that can lead to genetic variation.
What is a mutation?
This sugar is found in the backbone of DNA.
What is deoxyribose?
This enzyme adds complementary nucleotides during replication.
What is DNA polymerase?
When DNA is being transcribed and used to make proteins the book analogy would describe it as being _______________
This rule states that the amount of adenine in DNA equals the amount of thymine, and cytosine equals guanine.
What is Chargaff’s rule?
The ends of linear chromosomes are protected by these repeating sequences.
What are telomeres?
These two scientists are credited with discovering the structure of DNA.
Who are James Watson and Francis Crick?
Because each new DNA molecule consists of one old strand and one new strand, DNA replication is described using this term.
What is semi-conservative replication?
the book analogy would describe DNA like a book in that it can be copied. What is this called?
What is replication.
Rosalind Franklin used this technique to help reveal the structure of DNA.
What is X-ray crystallography (or X-ray diffraction)?
This term refers to the complete set of genetic information in an organism.
What is a genome?
This type of bond holds the two DNA strands together between complementary base pairs.
What are hydrogen bonds?
The short fragments formed on the lagging strand during DNA replication are called this.
What are Okazaki fragments?
What is the place in which the DNA separates for replication called?
What is the replication fork?
Griffith’s transformation experiment suggested that DNA could do this between bacteria.
What is transferring genetic material?
When did James Watson die? (Give me month and year)
