DNA Structure
Watson and Crick used this term to describe the shape of DNA.
What is a double helix?
This is what results from copying one molecule of DNA
What are two molecules of DNA?
A long, single stranded sequence of RNA. (Use full name)
What is messenger RNA (mRNA)?
This is where DNA replication takes place.
What is the nucleus?
A 3-base sequence of mRNA.
What is a codon?
The sugars and the phosphates.
What is the "backbone of a DNA molecule"?
This is the first step in the replication of one DNA molecule.
What is the unwinding of DNA?
This type of RNA carries an amino acid. (Use full name)
What is transfer RNA (tRNA)?
This is where transcription takes place.
What is the nucleus?
A 3-base sequence found on tRNA.
What is an anticodon?
The type of bond that holds bases together in the double helix.
What is a hydrogen bond?
This is what you call a "G" binding with a "C" or an "A" binding with a "T".
What is a base pair?
This type of RNA assembles itself into an "apple with a hole in it" through which mRNA can slither. (Use full name)
What is ribosomal RNA (rRNA)?
This is where translation takes place.
What is the cytoplasm?
With RNA, A (adenine) binds with this other base.
What is U (uracil)?
A (nitrogenous) base, a sugar, and a phosphate.
What are the 3 parts of a nucleotide?
The enzyme that is used to make a copy of a DNA molecule.
What is DNA polymerase?
This is the location of mRNA.
What is cytoplasm and nucleus?
This is what holds the mRNA strand in place while translation proceeds.
What is the ribosome?
Most of the amino acids of a protein are incorrect due to this type of mutation.
What is a frameshift mutation?
He is credited with the discovery that the amount of G's was roughly equal to the amount of C's (and A's with T's) in several samples of DNA.
Who is Erwin Chargaff?
The proteins which the DNA double helix winds around so that DNA can become "supercoiled".
What are histones?
The four major differences between DNA and RNA.
What is:
1. Smaller in size
2. Uracil instead of Thymine
3. Single Stranded
4. Has more than one type.
When mRNA is transcribed from DNA, it then slips through this to get into the cytoplasm.
What are the nuclear pores/nuclear membrane?
DNA is an abbreviation for this term.
What is deoxyribonucleic acid?
