who did research into the chemical composition of DNA helped lay the groundwork for James Watson and Francis Crick's discovery of its double-helix structure
Erwin Chargaff
which class of enzyme is required for unwinding the DNA at the replication fork?
DNA helicase
what is a sequence of 3 consecutive nucleotides that codes for a specific amino acid or signals the termination of gene translation
a codon
what is used in genetic engineering to a amplify, or produce many copies of, certain genes
Plasmid
what hydrogen bond is paired with guanine
cytosine
who is known for their work with James Watson which led to the identification of the structure of DNA in 1953
Francis Crick
what step is for filling in the DNA nucleotides into the gap created by the removal of RNA primers?
DNA polymerase
what is the process of making an RNA copy of a gene sequence
transcription
what are the organic molecules consisting of a nucleoside and a phosphate
nucleotide
what is the double coiled shape of DNA called
a double helix
who headed a group that included Rosalind Franklin, a crystallographer who produced DNA pictures that also aided the work of Crick and Watson.
Maurice Wilkins
what tells a scientists the kind of genetic information that is carried in a particular DNA segment
DNA sequence
what is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis.
Translation
what is the process of creating protein molecules.
protein synthesis
what bond is found only in RNA but not DNA
uracil
who discovered the molecular structure of DNA, a constituent of chromosomes that serves to encode genetic information.
Rosalind Franklin
what is made through a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual
DNA fingerprint
what is the name of a small RNA molecule that participates in protein synthesis.
tRNA (transfer RNA)
what is a laboratory technique used to separate DNA, RNA, or protein molecules based on their size and electrical charge.
electrophoresis
what is one of two classes of heterocyclic nitrogenous bases found in the nucleic acids DNA and RNA
pyrimidine
which pioneer molecular biologist discovered the double helix structure of the DNA molecule.
James Watson
