Hello students today we Are studying chapter gene its nature expression and regulation in that we are studying topic translation now translation is a process in which protein synthesis takes place let’s study how protein is made in human beings. Translation Translation means the synthesis of protein inside human body or any eukaryote a prokaryotic cell now what are these proteins an example of proteins could be your incident epinephrine growth hormones all these are proteins and they have to be formed by the process of translation artists for things important in human life and your life yes they are very important so the process of translation does not start on its own or it is the first process no it’s not like that first the process of DNA replication takes place inside nucleus then that unit replicate will form mRNA which is messenger RNA which would have information on its strand and then one mRNA is transcribed or transcription process forms mRNA along with information that codes for protein this mRNA is transferred to cytoplasm and now translation takes place so mRNA basically serves as a template or we can say serves as a pass for protein synthesis how does this process work mRNA will have information which is exposed information or exposed base fest in the nucleotide sequence and these nucleotides are in the form of photons especially in the triplet of three codons the first process that will take place is activation of amino acids now amino acids which are present inside your body or in your diet will be activated or we can say charge next transfer of activated amino acids with help of tRNA or you can say transfer RNA now once activated amino acids are transfer the help of tRNA this tRNA will have a anticodon sequence which would bind to the codon region on mRNA and once this codon anticodon matched match is done once you get is the nucleotides or you can say the amino acid polypeptide sequence is formed when I say polypeptide poly means many and peptide is the bond that’s formed when two different amino acids attached together once a long chain of amino acids is formed that will together assemble to give us a protein the chain is Tommy translation and when I speak about translation it is a process by which proteins are formed the process of synthesis of a protein molecule by using genetic information that is present in the form of codons special triplet codon on the MRNA or you talk about messenger RNA is called as translation and this persists takes place inside the cytoplasm of a cell the steps roll are the first step is activation or charging of amino acids and we all know amino acids and the smaller students of proteins which are joined together by peptide linkage next the activated amino acids are transferred with the help of tRNA and we all know tRNA is nothing but transfer RNA the next process is initiation of the polypeptide chains and when I’ve told you and the polypeptide chain is nothing but which is formed after a minor acids have linked together now once polypeptide chain has been synthesized a long chain is formed of polypeptides and this long chain is nothing but your protease and once this is done the chain basically terminates or stops students this is translation process now this is your mRNA or messenger RNA now this mRNA or messenger RNA has triplet codons for synthesis of proteins as you can say AUC is the first photon that codes for a protein with unit similarly these are other codons in the form of 3 that codes for protein to the mRNA what comes in by is your ribosomes which is your RNA now once ribosomes has find it ribosomes have P side and a side the P side is the entry side and a side is the exit side your tRNA will carry nucleotides which are nothing but anticodon and this anticodons will bind to the photon region to form anticodon and codon conflicts once this is done what happens is all the new amino acids form a polypeptide chain or long chain and this growing polypeptide chain is continuously formed once all the proteins are formed once all the proteins are formed then this chain would be terminated so the three different types of RNA that takes place is mRNA that’s messenger RNA and it which is ribosomal RNA and T RNA which is transfer RNA and this transfer RNA actually carries your activated amino acid as you can see it has carried serum which is a type of – all the 20 amino acids students inside body what we have is 20 different types of amino acids and all these 20 different types of amino acids join in certain fashion by forming the qualitative type chain students I hope you are understood that the process of translation is directly dependent on replication transcription and then translation without transcription translation cannot take this proteins can never be formed if there is no mRNA RNA and tRNA present inside your body I hope you are not clear with this concept of translation and synthesis of proteins thank you
