100
Eukaryotic DNA is coiled into these highly condensed structures.
What are CHROMOSOMES?
100

This person discovered the base pairings between nucleotides.

Who is Chargaff?

200
The shape of DNA, first published by Watson & Crick, is described as this. BONUS (100): What is the name of the scientist whose data Watson & Crick used without permission to form their hypothesis:
What is a double helix? BONUS: Who is Rosalind Franklin?
200
This enzyme unwinds the DNA molecule before DNA replication.
What is HELICASE?
200
Proteins are long chains made up of this type of molecule.
What are AMINO ACIDS?
200
This enzyme must bind to the promoter region of DNA in order to begin protein synthesis.
What is RNA POLYMERASE?
200

These people found out how to model DNA as a double helix

Who are Watson & Crick?

300
DNA is a polymer made up of monomers called __________.
What are nucleotides.
300
This disease can result when cells divide more frequently than usual.
What is CANCER?
300
These are the two steps of protein synthesis. BONUS: Where does each step occur in prokaryotes and eukaryotes?
What are TRANSCRIPTION and TRANSLATION? BONUS: Prokaryotes- both in cytoplasm Eukaryotes- Transcription in nucleus; translation in cytoplasm
300
The removal of this type of molecule allows chromatin to unwind in eukaryotic DNA so that transcription occurs.
What is a METHYL GROUP.
300

This person performed X-ray crystallography to find out facts about DNA structure.

Who is Rosalind Franklin?

400
This sugar is part of the backbone of the DNA molecule.
What is deoxyribose?
400
This enzyme is responsible for adding nucleotides to the strand of DNA that is being copied during DNA replication.
What is DNA POLYMERASE?
400
This type of RNA carries amino acids to the ribosome and binds to mRNA based on its anticodon.
What is tRNA?
400
Chromatin is wound around this protein when DNA is in its highly condensed form.
What is a HISTONE?
400

These people found out that DNA is the molecular basis for inheritance.

Who are Hershey and Chase?

500
Adenine and ___________ are both purines, while cytosine and ___________ are both pyrimidines.
What are GUANINE and THYMINE?
500
These two types of proteins are responsible for regulating cell division and destroying improperly dividing cells. BONUS (100): When cells are destroyed, they go through this process.
What are CYCLIN and CDKs? BONUS: What is APOPTOSIS?
500
Amino acids are linked together with this type of bond.
What is a PEPTIDE BOND?
500
Sequences of genes that are removed from mRNA before translation are called ____________.
What are INTRONS?
