Transcription occurs in the nucleus and translation occurs in the cytosol. Proteins are AUG-CUU-UAG / MET-PRO-VAL-VAL-ARG-ILE-LEU / MET-PRO GLY-TYR-ALA-MET-MET-SER-THR /  MET-ALA-TYR-THR-LEU

----------------------------------

Transcription

  • Transcription occurs in the nucleus. In RNA uracil replaces thymine.

  • While growing mRNA molecule,

→  adenine pairs uracil,

→  thymine pairs adenine, and

→  guanine pairs cytosine.

Translation

  • Translation occurs in the cytosol. mRNA codons codify for amino acids.

  • There is a start Codon AUG and stop codons UAA, UAG, UGA.

1.

DNA:       A T A C G A A A T C G C G A T C G C G G C G A T T C G G

mRNA:    U A U G C U U U A G C G C U A G C G C C G C U A A G C C  

Codon:     AUG   CUU   UAG    

here we recognize the start codon and a stop codon very close.

Anticodon: UAC   GAA    AUC   GCG   AUC   GCG   GCG   AUU   CGG    

Amino Acids:  MET -  LEU  

2.

DNA:    T T T A C G G C C A T C A G G C A A T A C T G G

mRNA: A A A U G C C G G U A G U C C G U U A U G A C C  

Codon:   AUG   CCG   GUA   GUC   CGU   UAU   GAC    

here we ONLY recognize the start codon but no stop codon.

Anitcodon:  UAC   GGC   CAU   CAG   GCA   AUA   CUG    

Amino Acids: MET - PRO - VAL - VAL - ARG - ILE - LEU
