🧬 Genetic Engineering Fundamentals
Genetic engineering involves the direct manipulation of an organism's genes using biotechnology to modify genetic material.
Gene Expression
The level of gene expression:
Expression = (mRNA_Level / Total_mRNA) × 100%
Where mRNA_Level is the messenger RNA level and Total_mRNA is the total mRNA in the cell.
Mutation Rate
The frequency of mutations:
Mutation_Rate = (Number_of_Mutations / Total_Base_Pairs) × 10⁶
Where mutations are measured per million base pairs.
Editing Efficiency
The efficiency of gene editing:
Efficiency = (Successful_Edits / Total_Attempts) × 100%
Where Successful_Edits are successful modifications and Total_Attempts are all editing attempts.
🧬 Key Insight: Genetic engineering enables precise modification of DNA sequences, allowing scientists to add, remove, or alter genetic material with unprecedented accuracy.
