12-3 RNA and Protein Synthesis

12-3 RNA and Protein Synthesis. Page 300. A. Introduction. 1. Genes are coded DNA instructions that control the production of proteins within the cell. B. The Structure of RNA. 1. RNA (Ribonucleic Acid) is similar to DNA because they are BOTH long chains of nucleotides.

Polypeptide Synthesis

Polypeptide Synthesis. From Genes to Proteins. Transcription in prokaryotes. Simple process No nucleus; ribosomes lie close to the DNA in cytoplasm 1 st part of the mRNA attaches directly to ribosomes The rest is being transcribed Assembly of aa into proteins begins right away.

Protein Synthesis

Protein Synthesis. By: Sophie gollan. In this experiment we modelled the structure of DNA and the processes involved in protein synthesis from the information in the DNA. DNA structure. DNA - a double stranded helix molecule which consists of subunits called nucleotides.

Translation

Translation. After transcription the mRNA strand is ready to start the process of protein synthesis. What part of the cell makes proteins?. Ribosomes Ribosomes use the sequence of codons in mRNA to assemble amino acids into polypeptide chains.
