Genetic engineering can be used to create more productive strains of farm animals. by adding genes to an animal’s dna, the animal can be made to produce milk or meat containing vital nutrients that would not be found naturally in those products. this provides a greater amount of nutrients per serving of milk or meat. what are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment?

The field of genetic engineering has remained controversial ever since its existence. Some scientists extremely favour the recombinant DNA technology whereas others consider it to be dangerous.

Some of the positive impacts would be that these animals would provide better milk quality and quantity. The meat of these animals will be able to provide better nutrition. Hence, in this way these animals will help to fight malnutrition.

The negative impacts of such animals would be that one never knows that if a mutation occurs in these organism than how dangerous it could be for the world. There is also a threat that the genetically engineered animals if mated with the wild life can cause threats. It might also lead to the wild- life of animals being extinct.

the answer is d.) homologous; have mammary glands

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
