You are applying to do work experience in a molecular biology
laboratory. As part of the application process you have been asked
Vocational Scenario or
to produce an illustrative report to demonstrate your understanding
Context
of DNA, RNA and protein synthesis and the consequences of error
occurring in protein synthesis.


Task Produce an illustrated report that assesses the impact of error in
the stages of protein synthesis, discusses the functional role of
nucleic acids in the stages of protein synthesis and explains the
structure and function of nucleic acids:

Explain the nucleotide structure and main features of the
following nucleic acids:
• DNA – stages and enzymes involved in DNA
replication
• RNA – mRNA, tRNA, rRNA, siRNA

, Discuss the functional role of these nucleic acids in protein
synthesis and the locations of each stage involved in protein
synthesis.




Discuss how the genetic code allows proteins to be synthesised
with minimal errors taking place, including:
• triplet codes
• codon
• anticodon
• degenerate code
• non-overlapping

Assess the possibility of errors occurring during the stages of
protein synthesis, particularly during transcription and
translation. Analyse the cause and effect of genetic mutations
in DNA, including:
• Missense
• Nonsense
• Silent
• Insertion
• Deletion
• Duplication
• frameshift

Provide examples of the impact that these errors may have on
the end products of protein synthesis.

Scientific terminology must be used accurately throughout your
report. You are encouraged to include photographs of models,
images or diagrams where appropriate, and reference your
sources.
Checklist of evidence An illustrative report that includes:
required • Assessment of the consequences of error during protein
synthesis
• Discussion about protein synthesis and the role of nucleic
acids
• Explanation of the structure and function of DNA and RNA
