Transcription
,Splicing and Translation
- Transcription is the process of making pre
mRNA using part of the DNA as a template
- 1.DNA helicase acts on the specific regions and break down the
hydrogen bonds between the bases and causing the strands to
separate.
- 2.RNA polymerase moves to the template strand
causing the nucleotides on the strand to join with the
complementary nucleotides.
- Guanine pairs up with Cytosine
- Thymine pairs to adenine
- Adenine pairs up with Uracil
- Guanine pairs up with Cytosine
- RNA polymerase adds the nucleotides to
build a strand of pre mRNA
- RNA polymerase reaches the end and
attaches stop codon. The production of
pre mRNA is then complete.
- Splicing
- the pre-mRNA is modified to mRNA by removing
the base sequences copied from introns.
- Cytoplasm
- Ribosomes
- Translation
- A ribosome becomes attached to the starting
codon on the end of mRNA molecule.
- tRNA molecule with the complementary anticodon
sequence moves to the ribosome and pairs up with the
sequence on the mRNA. This tRNA carries an amino acid
- By the means of an enzyme and ATP, amino acids on the tRNA
joined by peptide bonds.
- As this happens, the first tRNA is released from its
amino acid and is free to collect another amino acid
- As this process happens, 15 amino acids being linked
each second, until the polypeptide chain is built
- *Assembled into protein (primary
structure, secondary and tertiary)

- Mutation can affect the splicing of pre- mRNA.
