Mutations
100
These are the subunits of DNA.
What are nucleotides?
100
This molecule serves as a template for making mRNA.
What is DNA?
100
These are the subunits of proteins.
What are amino acids?
100
This results in two DNA double helices with each double helix having an orginal strand and a new strand.
What is semi-conservative DNA replication?
100
This type of mutation occurs when one base is substituted for another. A single base change in DNA.
What is a point mutation?
200
These 3 things make up the DNA subunit.
What are phosphates, sugars, and nitrogenous bases?
200
Transcription takes place here.
What is the nucleus?
200
This molecule serves are a template for making proteins.
What is mRNA?
200
This enzyme breaks the hydrogen bonds in the original DNA strand.
What is helicase?
200
This type of mutation occurs when one or more bases or added or deleted.
What is a frameshift mutation?
300
These two things make up the backbone of DNA.
What are sugars and phosphates?
300
After transcription, mRNA translocates here.
What is the cytoplasm?
300
This type of RNA brings the amino acids to the ribosome to aid in making proteins.
What is tRNA?
300
This enzyme adds complementary bases to the single stranded DNA.
What is DNA polymerase?
300
This is a physical or chemical agent that can cause a mutation.
What is a mutagen?
400
This type of bond joins two bases together.
What is a hydrogen bond?
400
mRNA has to attach to this organelle before protein synthesis can began.
What are ribosomes?
400
Translation occurs here.
What is in the cytoplasm on the ribosomes?
400
This is the reason DNA is replicated.
What is so that each new cell can have a full library of instructions?
400
This disease can result from a mutation in body cells.
What is cancer?
500
This type of bond joins the two things that make up the DNA backbone together.
What is a phosphodiester bond?
500
mRNA contains 3 letter bases that code for specific amino acids. Those 3 letter bases are called ____________.
What are codons or triplets.
500
This type of bond holds the amino acids together.
What is a peptide bond?
500
When DNA is replicated, if one strand has GCAATT, then what would be the sequence of the complementary strand?
What is CGTTAA?
500
Mutations can be passed down through these cells.
What are gametes (sperm or egg cells)?
