2. •Student will be able to,
•Define translation.
•Discriminate transcription and
translation.
•Explain the process of
translation.
•Draw initiation complex.

3. •Transcription- It is the process of
formation of RNA from DNA

6. •What is translation ?
•Key players of translation
•Steps in translation
•Charging (activation of A.A)
•Initiation
•Elongation
•Termination

7. •It is the process by which genetic
information coded in m-RNA
converted in the form of a
polypeptide.

8. •Ribosome
•M-RNA
•T-RNA
•Amino acid

9. •These are
ribonucleoprotein
particle, provide
the site for protein
synthesis.

11. •Messanger RNA carry the information
in the form of genetic code for a
specific protein required by body.s
•Structure:

12. •Transfer RNA
•Structure:Cloverleaf model of t-RNA

13. •There are 20 amino acid
identified in our body.These are
the unit of protein, aggregate by
the process of translation to form
a polypeptide.

+ P-P
+ t-RNA
(T-RNA-Amino acid)

15. •Translation of m-RNA begins with
the formation of initiation complex.
•It involves :Smaller sub unit of
ribosome, m-RNA,Charged t-
RNA,GTP,Mg2+,Initiation factors Ifs.

23. Polypeptide chain is terminated
when t-RNA find termination codon
on m-RNA.
Termination codons are
AAU, AGU, AUU

25. •In translation process many ribosomes
are attached in m-RNA and formed
polysome.
•Structure:

26. •Define Polysome.
•What is peptide bond ? How it
formed ?
•Name the structures involved in
the formation of initiation
complex
•What are initiation and
termination codon ?

27. •THANKS TO ALL
