|
What is an organelle, located in the cell's cytoplasm, that is the site of protein synthesis?
|
ribosome
|
|
|
What is the process in protein synthesis in which DNA's information is copied onto messenger RNA (mRNA)?
|
transcription
|
|
|
What is the process in which a polypeptide chain is produced within a ribosome based on the information encoded in messenger RNA?
|
translation
|
|
|
What is the enzyme in the transcription phase of protein synthesis that unwinds the DNA double helix and puts together a chain of RNA nucleotides complementary to the exposed DNA nucleotides?
|
RNA polymerase
|
|
|
What is a type of RNA that encodes, and carries to ribosomes, information for the synthesis of proteins?
|
messenger RNA (mRNA)
|
|
|
What is an mRNA triplet that codes for a single amino acid or a start or a stop command in the translation stage of protein synthesis?
|
codon
|
|
|
What was the inventory of linkages between nucleotide triplets and the amino acids they code for?
|
genetic code
|
|
|
In protein synthesis, what was the form of RNA that binds with amino acids transfers them to ribosomes, and then binds with a messenger RNA sequence?
|
transfer RNA (tRNA)
|
|
|
What was the end of the transfer RNA molecule that can bind with a particular codon on the mRNA transcript?
|
anticodon
|
|
|
What is the type of RNA that, along with proteins, forms ribosomes?
|
ribosomal RNA (rRNA)
|
|
|
What is the site on a segment of DNA to which RNA polymerase attaches prior to beginning transcription?
|
promoter sequence
|
|
|
What is the process in genetics in which a single primary transcript can be edited in different ways to yield multiple messenger RNAs, which in turn yield multiple proteins?
|
alternative splicing
|
|
|
What is a series of amino acids linked in a linear fashion?
|
polypeptide
|
