Protein Synthesis

The protein synthesis process involves many parts of the cell, the main steps occur in the nucleus and ribosomes. Unlike other similar products, this process is very complex and precise and should be done in the right order to work effectively.

The process involves two steps are transcription and translation. With the process of synthesis of DNA in a form of RNA called mRNA is used it is used to transport a model for ribosomes where translation occurs, the mRNA is protein synthesis is more effective.

The first step involves transcription of DNA sequence by breaking the hydrogen bonds, and an area will be copied to RNA; This is known as a cistron. A strand of this DNA will be a model and free nucleotides complementary bases it meets next. This process involves an enzyme called RNA polymerase which moves along this part and assembles the mRNA nucleotides into a strand. After the actions of the enzyme DNA will wind up by reforming hydrogen bonds. DNA mirror images will now be trained and will go out of free ribosomes and rough ribosome core of the endoplasmic reticulum.

The next step is to have the translation, it requires tRNA and mRNA that is in the form of a cloverleaf molecules due to loop over the other due to hydrogen bonds. The task is to pick up and transport the amino acids to the ribosomes and it has a site where the amino acids attached. There are 20 types of a tRNA for each amino acid attaching an amino acid to the tRNA is known as activation.

to ribosomes there are two sites known as the P and a ribosome sites move along the mRNA. The ribosome attaches to two specified codons and tRNA corresponding to the codons attaches to the ribosome and anticondon site tRNA attaches to the mRNA codon. On the P site of a peptide bond is formed between the amino acids and the ribosome moves diameter and the energy created by breaking the bond between the tRNA and the release of the amino acid is used to form a bond peptide to the previous amino acid and following. More than a ribosome can read this code at some point if a large amount of protein can B occurred. The arrangement of the peptide chain depends on the arrangement of the codons of mRNA, is what allows different proteins.
