2
How many strands of genetic information make up RNA?
One
This animal was the first mammal to be cloned.
Dolly the sheep
Where is DNA located in the cell?
Nucleus
The heriditary information of the cell
DNA (RNA)
These are on the outside of the DNA strand.
Sugars and phosphates
RNA does not have this nucleotide
Thymine
Which two scientists were given the Nobel Prize for DNA's discovery?
Watson and Crick
Where are chromosomes found?
Segments of DNA that carry heriditary instructions to be passed on to offspring.
Genes
How do the nucleotides pair up in DNA?
A-T
G-C
In RNA the A (adenine) pairs up with this nucleotide.
Uracil
This scientist discoverd how nucleotides bind together according to his rules.
Chargaff (Chargaff's Rules)
Which of the following is the SMALLEST?
Gene, chromosome, nucleotide, nucleus
Sunlight. Excessive exposure can cause mutations.
Ultraviolet Radiation
These are on the inside of the DNA strand.
Nucleotides
RNA has this nucleotide instead of thymine.
Uracil
This scientist gave her life for the structure of DNA to be found.
Rosalind Franklin
Which of the following is the LARGEST?
Gene, cell, chromosome, nucleus
cell
A change in the nucleotide sequence of DNA or RNA.
Mutation
The twisted stair step shape of DNA is called what?
Double Helix
If a strand of RNA has 20% uracil, how much adenine will it have?
20% (adenine binds to uracil)
This person discoverd that DNA was the genetic information, not protein.
Oswald Avery
There are this many chromosomes in the human body.
46
Two different forms of the same gene.
Alleles
