DNA Replication
100
This kind of bond holds the strands of DNA together.
What are hydrogen bonds.
100
This pair of gentlemen discovered the structure of DNA.
Who are Watson and Crick
100
RNA stands for this
What is ribonucleic acid
100
When mRNA attaches to one end of a ribosome, it's called this.
What is initiation
100
DNA replication occurs during this part of interphase.
What is the S phase
200
DNA is made of a pentose sugar called this.
What is Deoxyribose
200
These two individuals used bacteriophages to show that DNA, not protein, was the cell's hereditary material.
Who are Hershey and Chase
200
RNA is a molecule with this many strands
What is one
200
During translation, mRNA brings the copied DNA coded from the nucleus to this part of the cell.
What is the cytoplasm
200
DNA replication requires much ATP (energy) and this in order to occur.
What are enzymes
300
DNA appears as what when the cell is not dividing.
What is chromatin
300
This man in 1902 discovered DNA in chromosomes.
Who is Walter Sutton.
300
Instead of thymine, RNA contains this nitrogen base.
What is Uracil
300
tRNA with its attached amino acid have this many binding sites.
What is two
300
This enzyme uncoils and breaks the weak hydrogen bonds between complementary bases
What is DNA Helicase
400
DNA contains the instructions for making protein from this many amino acids.
What is 20
400
This woman used x-rays to photograph DNA crystals.
Who is Rosalind Franklin.
400
In RNA, uracil pairs with this base.
What is adenine.
400
This reads and temporarily attaches to the mRNA codon in the ribosome.
What is the tRNA anticodon
400
DNA replication begins at the origins of replication where two strands open and separate making this.
What is a replication fork
500
Thymine and Cytosine are bases known as pyrimidines while bases adenine and guanine are known as this.
What are purines.
500
This scientist worked with Streptococcus pneumonia and conducted transformation experiments of virulent and nonvirulent bacterial strains.
Who is Frederick Griffith.
500
The three types of RNA are this
What are mRNA, tRNA, and rRNA
500
Ribosomes move along the mRNA strand until they reach a stop codon called this.
What is termination
500
This part of DNA replication adds new nucleotides to the exposed bases in the 5' to 3' direction.
What is DNA Polymerase
