InvincibleBoy: Translation: Process of synthesis of protein from mRNA with the help of Ribosomes.
InvincibleBoy: 3 stages are involved in protein synthesis
InvincibleBoy: 1) Initiation : It involves the assemble of a ribosome on mRNA. Further activation of Amino acid takes place.
InvincibleBoy: 2) Elongation: Repeated cycle of Amino acid delivery, peptide bond formation and movement along the mRNA called translocation.
InvincibleBoy: 3) Termination: Release of a polypeptide chain.

InvincibleBoy: wobble hypothesis was proposed by Crick in 1966.
InvincibleBoy: Wobble Hypothesis : the base in first position of anti-codon on tRNA is usually an abnormal base, like inosine, pseudouridine, tyrosine etc. These abnormal bases are able to pair  with more than one type of nitrogenous base in the third position of the codon on mRNA.

Translation is the second stage in theprocess of protein synthesis where a piece of mRNA (formed in Transcription) is used to create a polypeptide chain. Translation takes place in the cytoplasm and the first thing that happens is that the ribosome attaches to the mRNA at the start codon

HERE IS YOUR ANSWER



In translation, messenger RNA (mRNA) is not decoded in a ribosome to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell. The ribosome facilitates decoding by inducing the binding of complementary tRNA anticodon sequences to mRNA codons. The tRNAs carry specific amino acids that are chained together into a polypeptide as the mRNA passes through and is "read" by the ribosome.

Translation proceeds in three phases:


Initiation: The ribosome assembles around the target mRNA. The first tRNA is attached at the start codon.


Elongation: The tRNA transfers an amino acid to the tRNA corresponding to the next codon. The ribosome then moves (translocates) to the next mRNA codon to continue the process, creating an amino acid chain.




Termination: When a stop codon is reached, the ribosome releases the polypeptide.
