Biology Quiz

1. Genetic Engineering is a molecular technique in biology that enable a gene or genes to be installed in a genome of an organism requiring molecular biology tools to successfully integrate the DNA and rDNA.

• TRUE

• FALSE

Which of the statements is true?

• GMOs lack the same nutritional value as its standard counterpart.

• GMOs have the same standard characteristics with the addition of improvements, but it still carries allergens that its standard counterparts do not carry.

• GMOs have the same standard characteristics with the addition of improvements, but it does not carry allergens that is also not present in its standard counterpart
