Answer:
The correct answer is C. The tertiary structure of a polypeptide is the overall three-dimensional shape of a fully folded polypeptide.
Explanation:
A polypeptide is a molecular chain composed of at least 10 amino acids (which are the molecules that make up proteins). When we talk about its tertiary structure, it refers to the complete overall three-dimensional structure of the polypeptide units of a given protein, where the polypeptide chain is fully folded and compacted. This folding is facilitated by unions called disulfide bonds, which are created from the cysteine residues, these bonds (called disulfide bridges as well) help to stabilize many polypeptides.
Answer:
The technique that is used in inserting a gene into a crop is genetic modification.
What is genetic modified crop?
A genetically modified organism (GMO) is a living organism whose DNA has been altered using genetic engineering techniques.
Humans have used breeding methods to modify organisms for thousands of years. Over generations, corn, cattle, and even dogs have been selectively bred to have certain desired traits.
The majority of GMO crops grown today were developed to assist farmers in preventing crop and food loss and controlling weeds.
The following are the most common traits found in GMO crops: Resistance to certain harmful insects, and Tolerance to certain weed-controlling herbicides.
Thus, with the help of genetic modification, a gene that controls beta-carotene production can be successfully inserted into a common food crop.
Answer:
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
