Question | Answer |
---|---|
What is transcription? | the process by which RNA polymerase uses a DNA template to produce mRNA |
What is an operon? | 2 or more genes in bacterial chromosome--transcribed into one mRNA molecule--eukaryotic cells do not have operons |
What is translation? | process of rRNAs translating the mRNA codons into proteins by polymerizing correct amino acids in the correct order |
RNA polymerase | used to produce the RNA copy of each gene |
mRNA | a template for the coded genetic information in DNA to be translated into protein |
Ribosomes | enzymes that carry out the process of translation |
Codon | nucleotide triplet that codes for a specific amino acid |
What is coupled transcription and translation? | the simultaneous synthesis of RNA and protein that occurs in the cytoplasm of prokaryotes |
What does a triplet of bases encode? | each triplet codon in mRNA codes for one amino acid |
