Transcription Basics
The enzyme that separates DNA strands and builds an RNA copy.
What is RNA polymerase?
This modification adds a backward G nucleotide to the 5' end.
What is the 5' cap?
The cellular location where translation occurs in both prokaryotes and eukaryotes.
What is the cytosol?
The number of nucleotides in a codon.
What is three?
The first amino acid added during translation.
What is methionine?
The DNA sequence where transcription begins.
What is the promoter?
This tail increases mRNA stability in the cytosol.
What is the poly‑A tail?
The RNA molecule that carries amino acids and has an anticodon.
What is tRNA?
The start codon that codes for methionine.
What is AUG?
The step where the ribosomal subunits and initiator tRNA assemble.
What is initiation?
The strand of DNA that RNA polymerase reads.
What is the template strand?
Non‑coding sequences removed from pre‑mRNA.
What are introns?
The enzyme that attaches the correct amino acid to each tRNA.
What is aminoacyl‑tRNA synthetase?
The three stop codons. (One id fine)
What are UGA, UAG, and UAA?
The stage where amino acids are added one by one.
What is elongation?
The three stages of transcription.
What are initiation, elongation, and termination?
The complex of small RNAs and proteins that removes introns.
What is the spliceosome?
The ribosomal site where new aminoacyl‑tRNAs first bind.
What is the A site?
The property of the code meaning multiple codons can specify the same amino acid.
What is redundancy?
The base‑pairing event between codon and anticodon.
What is codon recognition?
The type of RNA that is a “photocopy” of a gene.
What is mRNA?
The process that allows one gene to produce multiple mRNAs.
What is alternative splicing?
The catalytic molecules in the ribosome that form peptide bonds.
What are rRNAs (ribozymes)?
The rule that each codon specifies only one amino acid.
What is non‑ambiguity?
The ribosomal site where the growing polypeptide is held.
What is the P site?
