Recombinant DNA technology (Genetic Engineering) allows genes to be transferred

Across different species of plants.
From animals to plants.
From microorganisms to higher organisms.

Select the correct Solution using the codes given below.

Select an option to attempt

Explanation

Statement 1 is Correct: Recombinant DNA technology allows for the movement of genes across different plant species to introduce desirable traits, such as transferring genes from wild grass species to cultivated wheat to improve disease resistance.

Statement 2 is Correct: Genes can be transferred from animals to plants. A well-known research example involves transferring antifreeze protein genes from cold-water fish (like the winter flounder) into plants like tomatoes and strawberries to enhance their frost tolerance.

Statement 3 is Correct: Genes from microorganisms are routinely transferred to higher organisms (plants and animals). For example, genes from the soil bacterium Bacillus thuringiensis (Bt) are transferred into crops like cotton and corn to provide resistance against lepidopteran pests.
