An application says what genetic technology does. A limitation says what holds it back or what risk remains. Sorting each point before you write it keeps the two apart.
This lesson follows explaining biotechnology processes at syllabus level and belongs to the genetic technology lessons in SPM Biology.
How do I sort a point?
Ask two questions of any statement.
- Does it describe a use, a product or a gain? If yes, it is an application.
- Does it describe a cost, a risk, an uncertainty or a restriction? If yes, it is a limitation.
If a sentence contains both, split it into two.
Worked example: an invented pest-resistant crop
An original scenario: a crop variety is modified to produce a trait that reduces damage from a pest.
| Statement | Sort | Reason |
|---|---|---|
| Farmers use fewer sprays on the modified crop | Application | Describes a use and a gain |
| The modified trait may spread to related wild plants | Limitation | Describes an uncertain risk |
| Developing the modified variety takes years of testing | Limitation | Describes a cost in time |
| The trait protects the crop through its whole growth period | Application | Describes what the trait does |
The technology is the same in all four rows. The sort depends on what each sentence claims.
The mistake that costs marks
The common slip is to write a benefit under a limitation question. A student asked for one limitation writes that the crop gives a higher yield.
| Claim | Why it fails |
|---|---|
| “Limitation: the crop has a higher yield” | A higher yield is a benefit |
| “Application: it may harm other organisms” | That is a risk, so a limitation |
| Correct limitation: “The long-term effect on other organisms is not yet known” | States the uncertainty |
Before you start writing, underline the command word: application or limitation.
Check yourself
Sort these into application or limitation: (a) bacteria making a needed protein, (b) the equipment is expensive, (c) a gene moved between species raises ethical questions, (d) a crop gains a trait that helps it grow in dry soil.
Answer
(a) Application: it describes a use and a product.
(b) Limitation: it describes a cost.
(c) Limitation: it describes an ethical concern.
(d) Application: it describes what the trait does for the crop.
What to study next
Continue with evaluating benefits and risks using evidence, where you weigh the two using data. The biological data interpretation trainer gives you practice in careful wording.
