Human growth hormone is genetically engineered and inserted into human tissue to stimulate growth in people with dwarfism. what are possible concerns that scientists have about the long-term effects of this process? a: whether it will mutate b: whether it will result in allergens c: how it will impact nutrition d: how it will enhance disease resistance

The correct answer would be A: whether it will mutate

The main concern of scientists in case of genetic engineering is the mutation of the gene inserted in an organism.

Mutation is a random process that can occur spontaneously and as a result of replication errors.

These are inheritable if occur in germ cells.  

Mutation of a gene can result in the production of an altered protein which may have lost its function. In adverse cases, the altered protein can even hamper the normal functioning of an organism.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
