Question

how do scientists use the process of genetic engineering?
a to combine an organisms rna proteins with its dna
b to map out the sequence of nucleotides in human dna
c to change the arrangement of genes in an organisms dna
d to insert the dna of one organism into another organism

Explanation:

Genetic engineering involves manipulating an organism's DNA. Option A is incorrect as RNA proteins are not combined with DNA in this process. Option B refers to mapping DNA (like the Human Genome Project), not genetic engineering. Option C is about changing gene arrangement within an organism's own DNA, which is not the main focus of genetic engineering. Option D correctly describes the core of genetic engineering - inserting DNA from one organism into another.

Answer:

D. To insert the DNA of one organism into another organism
