it is the full presentation on protein biosynthesis which elaborates whole process for protein synthesis

2. Some Questions related to the
topic
- - What is protein?
- - Why protein synthesis is
necessary?
- - Does protein synthesis show
any other clues about life ?

3. - Nucleus
- Nuclear pores
- DNA
- RNA & its types
- Cytoplasm
- Rough endoplasmic
reticulum
- Ribosomes
,

4.  1st Step - TRANSCRIPTION
 2nd Step - TRANSLATION

5.  - it is the first step of protein biosynthesis without
this step protein synthesis inside a living body is
impossible
 - It takes place inside the nucleus of cell
 - in this step DNA strands are unzipped by
helicase enzyme to produce one strand of RNA
that RNA is called mRNA
 - the information needed for the synthesis of
particular protein is thus copied into messanger
RNA from DNA and that is called “CODON “

6.  - CODON consist of especial codes of
that protein is to be synthesized.
 - this mRNA moves out and act as carrier
of information to the cytoplasm through
the facilitation of nuclear pores.
- Transcription is completed here and
translation starts..

7.  - It is the second step of protein
biosynthesis.
 - It takes place inside the cytoplasm.
 - Here from title word we can know in
this the information is deciphered or
translated to make a particular required
proteins.
 - In translation two types of RNAs are
processed i.e tRNA and rRNA

8.  - ribosomal RNA is situated at
ribosomes while tRNA is all around the
cytoplasm to collect and supply the
required amino-acids to make
polypeptide chain , to the ribosomes.

9.  -ribosomal RNA assembles amino acids
here at the ribosomes present at the
rough endoplasmic reticulum . in a
proper sequence as required by the
knowledge given by mRNA to
synthesize required protein thus
ribosomes are called protein factories

10.  For all facilitations , courages and
motivations to make this presentation not
only but making able of doing a little
progressive work for building up
confidence to build a better carrier
