Watson and Crick used this term to describe the shape of DNA.
double helix?
100
This is what results from copying one molecule of DNA
molecules of DNA?
100
A long, single stranded sequence of RNA.
messenger RNA (mRNA)?
100
This is where DNA replication takes place.
the nucleus?
100
base sequence of mRNA.
a codon?
200
The sugars and the phosphates.
"backbone of a DNA molecule"?
200
This is the first step in the replication of one DNA molecule.
the unwinding of DNA?
200
This type of RNA carries an amino acid.
transfer RNA (tRNA)?
200
This is where transcription takes place.
the nucleus?
200
A 3-base sequence found on tRNA.
an anticodon?
300
The type of bond that holds bases together in the double helix.
a hydrogen bond?
300
This is what you call a "G" binding with a "C" or an "A" binding with a "T".
a base pair?
300
This type of RNA assembles itself into an "apple with a hole in it" through which mRNA can slither.
ribosomal RNA (rRNA)?
300
This is where translation takes place.
the cytoplasm?
300
With RNA, A (adenine) binds with this other base.
U (uracil)?
400
A (nitrogenous) base, a sugar, and a phosphate.
3 parts of a nucleotide?
400
The enzyme that is used to make a copy of a DNA molecule.
DNA polymerase?
400
what is RNA?
Ribonucleic acid is a ubiquitous family of large biological molecules that perform multiple vital roles in the coding, decoding, regulation, and expression of genes
400
This is what holds the mRNA strand in place while translation proceeds.
the ribosome?
400
Most of the amino acids of a protein are incorrect due to this type of mutation.
frameshift mutation?
500
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.
Erwin Chargaff?
500
The proteins which the DNA double helix winds around so that DNA can become "supercoiled".
histones?
500
who make proteins?
ribosomes
500
When mRNA is transcribed from DNA, it then slips through these to get into the cytoplasm.
