Answer each of the following correctly. Designer Genes Work (This is all about Applications of Recombinant DNA).
1. What is Genetically Modified Organism (GMO)?(1-4 sentences only)
2. Illustrate your own Designer genes using this information:
The Arctic apple is a fruit engineered to resist browning after being cut. Currently they are only available in the US – in golden, fuji and gala varieties – where they have been given Food and Drug Administration approval. If approved in Europe, they would have to be labelled as genetically modified. The manufacturers claim the main benefit is to help cut down on food waste. And based on the following:
a. Identify a special trait.
b. Identify a source organism.
c. Identify a target organism
d. Identify the modified/added trait.
Example:
Hot Tomato > Chili > Tomato > Spicy Tomato
It was reported this week that Brazilian scientists are hoping to create spicy tomatoes using Crispr gene-editing techniques. Although tomatoes contain the genes for capsaicinoids (the chemicals that give chillies their heat) they are dormant – Crispr could be used to make them active. This is desirable because, compared to tomatoes, chillies are difficult to farm – and capsaicinoids have other useful applications besides their flavour – in pepper spray for example.
