In DNA, adenine always pairs with ______________.
What is thymine?
100
An adenine on a molecule of DNA corresponds to what base on messenger RNA?
What is uracil?
100
This organelle converts mRNA to protein.
What is the ribosome?
100
This is a photograph of human chromosomes that can be used to diagnose genetic disorders.
What is a karyotype?
100
This is when organisms that possess desirable traits are mated together in order to produce offspring that also possess those traits.
What is selective breeding?
200
These are the two scientists who discovered that DNA was a double helix.
Who are Watson and Crick?
200
This is the sugar present in any nucleotide of RNA.
What is ribose?
200
This is the process that converts DNA to mRNA.
What is transcription?
200
These two mutations are considered "frame-shift" mutations.
What is an insertion and a deletion?
200
This is a molecule that recognizes specific base sequences of DNA and cuts the DNA at those locations.
What is a restriction enzyme?
300
These are the three components of any nucleotide that makes up DNA. (Be specific)
Phosphate, Deoxyribose Sugar, Nitrogen Base
300
This type of RNA serves as a "middle man" between DNA and amino acids.
What is messenger RNA?
300
This is what we call every three bases of mRNA.
What is a codon?
300
This disorder is caused by non-disjunction of homologous chromosomes during meiosis.
What is Down Syndrome?
300
When an animal is cloned, the nucleus of an egg cell is removed and replaced with what?
What is the nucleus from a body cell?
400
This is the first step of DNA replication.
DNA untwists and the two strands separate.
400
This type of RNA has an anti-codon on one end, and an amino acid on the other end of its molecule.
What is transfer RNA?
400
This is the process in which mRNA is converted into a string of amino acids.
What is translation?
400
Name two causes of genetic mutations.
Tobacco, radiation, UV rays, X rays, asbestos, faulty DNA replication.
400
This is why we use DNA fingerprinting.
What is paternity testing and solving crimes?
500
12% of the bases on a strand of DNA are cytosine. What percentage are adenine?
What is 38%?
500
True or False: RNA is found in both the nucleus and the cytoplasm of all cells.
TRUE
500
This is the complementary base sequence to a codon of mRNA.
What is an anticodon?
500
True or False: A genetic mutation in a woman's skin cell caused by exposure to UV light can be passed on to her offspring.
FALSE
500
This is why genetic engineering is also called "recombinant DNA technology."
A segment of human DNA is COMBINED with bacterial DNA and then placed back into a bacterial cell.
