Transcription & Translation Flashcards
Process of making RNA from DNA
Transcription
Enzyme that catalyzes the formation of RNA from nucleotides
RNA Polymerase
Enzymes attached to one end of the DNA template and moves along the template, adding nucleotides one at a time
RNA Polymerase
3 main forms of RNA
Messenger (mRNA), Transfer (tRNA), and Ribosomal (rRNA)
RNA that carries genetic code from the DNA in the nucleus to the ribosomes in the cytoplasm
Messenger (mRNA)
RNA that helps to assemble amino acids into proteins that act as adapters in the translation of the genetic sequence
Transfer (tRNA)
RNA that makes up ribosomes
Ribosomal (rRNA)
DNA double helix _____ and ___ ___ of the DNA serves as a template for RNA synthesis
Unwinds; 1 Strand
When RNA synthesis is complete the RNA molecule is released from the DNA _____
DNA double helix ____
Template; Reforms
Process of making proteins from RNA
Translation
Transcription occurs on ribosomes in the _____
Cytoplasm
____ attaches to the subunit of a ribosome and then _____ brings amino acids to the ribosome
Messenger (mRNA); Transfer (tRNA)
As amino acids are brought to the ribosome they are joined together by ____ ____ to form a ____
Peptide Bonds; Protein
Read in groups of 3 nucleotides called codons
Genetic Code
Each ___ codes for a specific amino acid
Condon
