Title: BTEC Applied Science Unit 18 Assignment 1
Description: Unit 18: Genetics and Genetic Engineering – Assignment 1 Protein Synthesis Task 1 Provide diagrams with notes to illustrate and describe the structure of DNA, mRNA and tRNA. Produce a table that summarises the differences between these nucleic acids This provides evidence for P1 Task 2 You are provided with a DNA sequence that codes for a short chain of ten amino acids. You must use the table of mRNA codes to work out the sequence of amino acids. You must show how you have worked out the sequence This provides evidence for M1 Task 3 You must provide a fully detailed account of protein synthesis. You must give full details of the two stages. The roles of mRNA and tRNA should be made clear. This would best be done by presenting a poster or making a PowerPoint presentation This provides evidence for D1 Exam board is Pearson ALL ASSIGNMENTS I HAVE UPLOADED ARE DISTINCTION GRADED.

polymerase dissociates, and the newly formed strand of RNA is released
...
The genetic info contained in the mRNA is used to determine the sequence of amino acids making the protein
...
The RNA strand leaves the nucleus through a nuclear pore and then enters the cytoplasm and attaches itself to a ribosome
...
The ribosome carries out the process of translation
...
These are called codons
...
3
...
The second tRNA binds to the next codon
...
The amino acid on the first tRNA (this is the start of the sequence) is joined to the the amino acid on the second tRNA (V) by a peptide bond
...
5
...
6
...
It reads the first codon
...
tRNA with a complementary anticodon binds with the third codon
...
A peptide bond forms between the second and third amino acids
...
The ribosome moves along the mRNA and the next codon is read
...
T always pairs with A
G always pairs with C
A always pairs with U
Then I used the genetic code to find out the amino acid sequence
...
A three base sequence in DNA or RNA is known as a codon
...
Then I added
the three digit code to the table in line with the codon of the mRNA
...
I repeated this for the next codon of the mRNA, then
the next and so on
...
This is called a STOP codon
...
There are both START and STOP codons
...
As shown on the table, that is the
amino acid, methionine (Met)
...
However, in some cases the methionine can get chopped off the
chain after synthesis is complete
