Multiple choice

A scientist wants to develop a new paddy variety through genetic engineering. This variety has the capacity to withstand cold temperature.

How can the scientist develop this variety?

  1. Increasing the length of fatty acid chain

  2. Eliminate all steroids

  3. Increase frequency of unsaturated fatty acid

  4. Decrease frequency of unsaturated fatty acid
