Protein Synthesis.

Firstly, What do genes do in the cell?
DNA controls cell activities by producing proteins, many of these proteins are enzymes. DNA work by having a double stranded Helix which uncoils the DNA bases uncoil (separate) the sequences in which the bases in DNA carry the instructions to make the correct protein RNA now forms new base pairs with one strand of DNA it is then and only then that it has converted from RNA to mRNA which is messenger RNA which leaves the nucleus and enters the cytoplasm. The cytoplasm of the cell also contains tRNA in other words Transfer RNA which carries an amino acid the amino acid comes from the protein that you intake in your own diet. tRNA and mRNA combine via the codons which are located at the start …show more content…

The sequence of bases on a DNA strand carries instructions in the form of a code to make a particular protein.
2. The bases in DNA and RNA work in groups of three. Each group of three bases causes one particular Amino Acid to become part of the protein being made.
3. The DNA strands separate. This step takes place in the nucleus of the cell
4. RNA bases attach to the exposed bases on one side of the DNA. This means that the code has been transcribed from DNA to a complementary strand of RNA this then leads to the making of messenger RNA (mRNA). *Transcription is the copying of genetic bases from DNA onto messenger RNA.
5. The MRNA strand detaches from the DNA and moves out of the nucleus into the cytoplasm.
6. The mRNA passes through a ribosome when it passes through each bases causes an amino acid to be attached to a particular protein that is made in the Ribosome. Which is then translated to a correct sequence of amino acids at a ribosome. *translation essentially is the conversion of a sequence of genetic bases on messenger RNA into an amino acid.
7. The protein becomes folded as it leaves the ribosome. This allows the protein to carry out a particular function.
