DNA Structure
In DNA, Adenine always bonds with this
What is thymine?
What is the nucleus?
The ends, or tips, of the chromosomes.
What are telomeres?
This woman was known for her famous x-ray photo of DNA?
Who is Rosalind Franklin?
The kind of bond that exists between sugar and phosphate of neighboring nucleotides.
What are covalent bonds?
The SHAPE DNA is described as is this.
What is a double helix?
The purpose of replication.
What is to produce 2 identical strands of DNA?
DNA replication occurs prior to this.
What is mitosis or cell division?
These scientists build a model of DNA.
Who are Watson and Crick?
This is the reason that DNA can replicate itself from one strand.
What is base pairing?
These two things make up the "backbone" of DNA.
what is phosphate and sugar? (Deoxyribose)
The point at which DNA strands are separated.
What is replication fork?
This enzyme adds additional pieces of DNA to the ends of chromosomes.
What is telomerase?
These scientists studied how viruses infect bacteria and supported Avery's claims.
Who are Hershey and Chase?
The idea that percentages of Adenine match up with Thymine, and that the percentages of Cytosine match up with Guanine, is called this.
What is Chargaff's rule?
This is the building blocks of DNA.
What is a nucleotide?
The two strands of DNA molecules twist around each other in this way.
What is antiparallel? (runs in opposite directions)
The type of bonds that have to break in order for replication to occur.
What are hydrogen bonds?
This scientist came before Avery in studying mice and how pneumonia infected them
Frederick Griffith
If a DNA strand had 40% cytosine, it would have this much adenine.
What is 10%?
These are the three parts of a nucleotide.
What is a phosphate, sugar, and a nitrogen base?
This enzyme checks for errors in the genetic code.
What is DNA polymerase?
These make up the 'rungs' of the DNA helix.
What are paired nitrogenous bases?
The name of Franklin's DNA X-ray that confirmed helix.
What is photo 51?
What are radioactive isotopes?
