The process of copying of the genetic information from one strand of DNA into RNA is termed as transcription. This is the first step required for synthesis. Transcription is also based on the complementarity of the strand. Also, only one strand of the DNA is converted into . One transcription unit consists of 3 regions: A promoter, the Structural Gene and a Terminator. The promoter is located towards the 5’ end and defines the template and coding strand. The terminator is towards the 3’ end defining the end of transcription process. The is transcribed in 5' to 3’ direction by polymerase.

The process of polymerization of amino acids to form a polypeptide is called as Translation. It is the second and final step of protein synthesis. The order into which the amino acids are arranged is defined by the bases in mRNA (messenger). Ribosome is the cellular factory responsible for the protein synthesis. The ribosome consists of structural RNAs and about 80 different . It is in inactive stage and exists as two subunits, one large and other small. The synthesis of begins when the small subunit encounters an mRNA. The ribosome also acts as a catalyst for the formation of bonds.

If you are looking to introduce or reinforce a unit on DNA, GENETICS, PROTEIN SYNTHESIS, or MUTATIONS, this engaging manipulative will seal the deal. Your students will be engaged throughout the entire activity. Also, this card game is utilzized satisfying multiple state objectives and is an ongoing formative assessment tool that really works.
Molecules of tRNA are formed in the nucleus and migrate into the cytoplasm. There are twenty different types of tRNA, one for each type of amino acid. Each type of tRNA can grab one kind of amino acid molecule. Each tRNA has a three-base segment called an which is complementary to a codon on the mRNA. In protein synthesis, a tRNA molecule carrying an amino acid molecule becomes attached briefly to the mRNA at a codon complementary to its anticodon. Then a tRNA complementary to the adjacent codon attached on the mRNA. A peptide bond forms between the two amino acid molecules carried by the tRNAs. Amino acids are added one at a time to the growing chain as the mRNA strand is "read." This continues until a termination (stop) codon is encountered. After each peptide bond is formed, the tRNA is released to go and pick up a new amino acid in the cytoplasm. Determine the anticodon for each codon below. Write it in the space provided.

The amino acids are joined to form proteins by peptide bonds. The formation of peptide bonds requires a good amount of energy. Therefore, in the first phase of translation for protein synthesis, the amino acids are activated in the presence of ATP and linked to their cognate tRNA (transfer RNA). This process is called as charging of the tRNA or aminoacylation of tRNA. If two such charged tRNA are brought close enough, the formation of peptide bond between them is favored energetically. This function occurs inside the , as it contains two sites for subsequent amino acids to bind to and thus be close enough for bonding.
For initiation of the translation process, the ribosome binds to the mRNA at the start codon recognized by the initiator tRNA. The ribosome then proceeds to the elongation phase of protein synthesis. During this stage, the complexes formed by amino acids are linked to tRNA, sub sequentially to bind to the appropriate codon in mRNA by forming complimentary base pairs with the tRNA anticodon. The ribosome moves from codon to codon along the mRNA. Amino acids are added one by one, translated into polypeptide sequences dictated by the DNA and represented by mRNA. At the end, release factor binds to the stop codon, thus terminating the translation stage and completing the protein synthesis process. The complete polypeptide is released from the .
