Recombinant DNA technology (Genetic Engineering) allows genes to be transferred<br/>1. across different species of plants<br/>2. from animals to plants<br/>3. from microorganisms to higher organisms<br/><br/>Select the correct answer using the codes given below.

1. Across different species of plants — Correct. Recombinant DNA technology can transfer useful genes between plant species; this is the basis of many transgenic crops.

2. From animals to plants — Correct. Genes from animals can be inserted into plants through genetic engineering if they confer a desired trait.

3. From microorganisms to higher organisms — Correct. A classic example is transfer of Bt gene from the bacterium Bacillus thuringiensis into plants.

Therefore, all three statements are correct.
