PROTEIN SYNTHESIS: TRANSLATION

PROTEIN SYNTHESIS: TRANSLATION. What is the genetic code?. the sequence of nt in mRNA the order of mRNA n.t . determines the order of amino acids that will bond to build a polypeptide the code is a triplet code: in mRNA, every 3 nucleotides codes for an aa called a CODON .

Drugs acting on bacterial protein biosynthesis

Drugs acting on bacterial protein biosynthesis. Proteins are very essential for most of the bacterial metabolic functions as well as for cell integrity. Bacterial cell uses ribosomes to synthesize proteins. Targeting protein biosynthesis will produce bactericidal agents in most of the cases .

11.5 Protein Translation

11.5 Protein Translation. Translation: Converts Nucleic Acid language into amino acid language. Codon : Is a 3 base “ word ” that codes for 1 amino acid found on mRNA Several codons form a “ sentence ” or a protein The triplet code: Each codon stands for a particular amino acid
