Protein Synthesis

Protein Synthesis Building Protein based on DNA Transcription DNA RNA Protein Transcription DNA RNA Translation RNA Protein

What is RNA? Like DNA with 4 differences RNA DNA Sugar Ribose Deoxyribose Strands 1 strand 2 strands Base pairs Uracil binds to Adenine Thymine binds to Adenine Length Short long

“The Workers” 3 types of RNA Messenger RNA (mRNA) Ribosomal RNA (rRNA) Carries instructions from gene to make protein Ribosomal RNA (rRNA) Part of the ribosome Transfer RNA (tRNA) Transfers amino acids to the ribosome

The Process Transcription Gene rewritten into RNA RNA polymerase reaches a START signal & begins to add free RNA nucleotides until it reaches the STOP signal

Transcription

The Process Translation mRNA directs the building of proteins tRNA & mRNA join together Codon- 3 nucleotide sequence in mRNA tRNA carries the amino acid that matches the codon Amino acid- basic building block of protein

Translation
