Its first isolated specific product was the lysozyme, a bactericidal substance, by Alexander Flemming.

Kryger [21]

Ans.

Genetically modified grasses are produced by using genetic engineering techniques, which contain genes for drought and disease resistance. Due to those genes, these grass varieties have higher chances to survive in stress condition and they spread with a fast and tremendous rate.

Most of the genetically modified grass varieties are still not approved by government, because 'these grass species may act as uncontrolled invasive species and cause harm to other useful plant species as they can spread fast and hard to wipe out due to resistance against stress conditions.'
