Genetic engineering can be used to disrupt specific genes in the genome of an organism. Predict how the browning of apple slices
adell [148]

Answer: Fruit will not brown. Browning requires a functional enzyme.

Explanation:

Genetic engineering refers to the manipulation of an organism's genes. Scientists use a variety of molecular tools and techniques to cut up and join genetic material from different species and to introduce this new hybrid DNA into another organisms. <u>The overall goal is to add or remove an organism's genetic makeup for the better, or to transfer DNA code from one species into the other, in order to form new combinations or heritable genetic material.</u>

Enzymatic browning is a reaction that occurs in fruits which results in negative effects on characteristics such as taste, color, and nutritional value. This reaction is a caused by phenolic compounds' oxidation by an enzyme called polyphenol oxidase, which causes the generation of dark pigments. This is often seen in apples which are rich in this enzymes and susceptible to this enzymatic browning.

If through genetic engineering, the gene encoding the enzyme responsible for the apple browing is removed, then this enzyme cannot be produced by the apple. Consequently, apples will not brown<u>,</u> because there will not be a polyphenol oxidase that oxidates the phenolic compounds.

12345 [234]

Answer:

The correct option is C: antigen-binding sites

Explanation:

The antibody is shaped much like the letter Y in the English alphabet. It has two antigen binding sites that are identical in nature. The specificity of these sites is determined by the amino acid sequence that makes it up. Antibodies are complementary to these antigen binding sites, and the antibodies have an incredible ability to recognize a great variety of antigens.
