Translation
| Question | Answer |
|---|---|
| 3 molecules required for translation | mRNA, tRNA, and rRNA |
| mRNA is translated to what | protein |
| translated from the codons on mRNA to ________ | amino acids |
| brings genetic code from DNA (mirror image) | mRNA |
| binds to amino acid. made up of 3 RNA bases | tRNA |
| tRNA is an ___________ | anticodon |
| the tRNA anticodon is transferred to a mRNA _______ | codon |
| ______ is that the ribsome is made up of and it reads the mRNA strand | rRNA |
| __________________ cells have 30S and 50S ribsomal unit (70S ribosomes) these two subunits join around the mRNA and create the peptide bonds between adjacent amino acids | prokaryotic |
| ___________ cells have 40S and 60S subunits (80S ribosomes) | eukaryotic |
| - mRNA binds to the ribosome - there is an initiator codon (AUG) on mRNA - the code mRNA (codon) determines which tRNA (anticodon) can bond to it | translation initiation |
| - peptide bond form - each tRNA has an amino acid attached to it. When two amino acids are brought together in the ribosome they are attached (dehydration synthesis) and a peptide bond is formed. -then the tRNA is free to go get another amino acid | translation elongation |
| -stop codon signifies that the pepetide chain is complete -this process continues until the terminator (stop) codon is reached. Then the protein detaches. | translation termination |
| in translation the amino acids are linked together by ______ _________ at the ribosome | dehydration synthesis |
| AUG | start codon |
| UGA, UAG, UUA | stop codon |
| in _____ cells the mRNA must leave the nucleus to be translated at the ribosome | eukaryotic |
| in _______ cells the mRNA can be translated as it is being transcribed | prokaryotic |
