(DNA Replication)
(DNA Replication)
What is the enzyme responsible for unwinding the DNA double helix during replication.
DNA Helicase
The process by which messenger RNA (mRNA) is synthesized from a DNA template.
transcription
This is the site in the cell where translation takes place.
Ribosome
This type of molecule binds to the promotor and initiates transcription.
RNA polymerase
Silent mutation
DNA replication is termed to be THIS as each new DNA molecule is composed of one original strand and one newly synthesized daughter strand.
Semiconservative
This enzyme is responsible for synthesizing RNA during transcription.
RNA polymerase
What is the three nucleotide sequence on the mRNA that codes for a specific amino acid called.
A codon.
This is the region of a gene that can have repressor proteins bind to prevent transcription from happening.
The operator.
This type of mutation happens when a single nucleotide is substituted for another in mRNA.
Point mutation
The enzyme that adds nucleotides to the growing DNA strand in the 5'-3' direction is called...
DNA polymerase
The sequence of DNA where RNA polymerase binds to initiate transcription.
Which molecule carries amino acids to the ribosome during translation?
tRNA
This form of gene regulation involves modification to mRNA after transcription but before translation.
Post-transcriptional control
A nonsense mutation results from a point mutation that causes what to occur in the mRNA where is shouldn't be.
A stop codon.
This strand of DNA is synthesized in fragments, which are later joined together by an enzyme.
The lagging strand
These non-coding regions of the gene are transcribed but removed during mRNA processing.
The introns
This phase of translation involves the ribosome reading mRNA codons to assemble a polypeptide chain.
This type of gene expression regulation refers to the control of initiation, as well as the efficiency and speed of translation, often by regulatory proteins.
translational control
Any agent/chemical/substance that causes a mutation in the DNA.
This structure is formed where DNA helicase is actively 'unzipping' the DNA molecule.
The replication fork.
This is the process of adding a 5' cap and a poly-A tail to mRNA, making it ready for translation.
What is mRNA processing OR post-transcriptional control
This sequence marks the beginning of translation and is always the first codon in mRNA. Also name the associated amino acid.
Start codon AUG and methionine or MET
This form of regulation involves changes to the protein after it has been synthesized, such as phosphorylation or associating with a coenzyme.
This type of mutation results from the substitution of a dissimilar amino acid which changes the structure of the protein, often reducing or eliminating the function of the protein.
A missense mutation
