DNA Structure
What is the location of DNA in the cell?
Chromosomes/Nucleus
Name the two scientists who stole another scientist's picture without giving her credit.
James Watson and Fracis Crick
In order to make a protein, DNA has to be _____ into mRNA. (Not "copied")
Transcribed (transcription)
Why is it called "messenger" RNA?
Because mRNA carries the "message" or instructions to make a protein. (DNA cannot leave the nucleous)
In RNA, Adenine binds with this amino acid
Uracil
Describe the Base-Pair Rule
In DNA, Adenine bonds with Thymine and Guanine with Cytosine.
Who is the woman who took a picture of DNA and was never given credit for her work until recently?
Rosalind Franklin
mRNA is made in this part of the cell
Nucleus

ATA CAC ATG GAG
TAT GAG TAC CTC
What is the structure of the DNA molecule?
Double helix
Which organelle translates mRNA into proteins?
Ribosomes
A chain of amino acids folds into a _____
Protein
What does RNA stand for? (spelling counts)
Ribonucleic acid
What is the molecule found between sugars in the DNA ladder?
Phosphates
What holds the bases in DNA together? (at the center of the ladder)
Hydrogen bonds
mRNA travels to the nucleus/cytoplasm to be transcribed/translated by a ribosome.
cytoplasm; translated
Why is DNA called "the blueprint of life"?
Because like a blueprint for a building, DNA has instructions to build life.
