Answer:
The options have been placed in the comment section. The answer is C. Inheritance of genes from both parents
Explanation:
Gregor Mendel is referred to as the FATHER OF GENETICS due to his immense contribution to the discovery of how traits are passed down or inherited from parents to offsprings. He found out that a unit of inheritance, which was later called GENE, was responsible for each individual trait of pea plants.
In his numerous experiments, Mendel discovered that the characteristics/traits of pea plants were determined by the contribution of both parents. Mendel hypothesized that each parent contributed 50% of this unit of inheritance via fertilization to the characteristics of an offspring. Hence, the inheritance of genes from both parents determines the characteristics of a pea plant.
Answer:
The options A, B, and D are all valid.
Explanation:
- The reason is that some proteins require molecular chaperones if they are to fold properly within the environment of the cell. In the absence of chaperones, a partially folded polypeptide chain has exposed amino acids that can form non-covalent bonds with other regions of the protein itself and with other proteins, thus causing nonspecific aggregation of proteins.
- The option A) is correct because the protein you are expressing in bacteria is being made in large quantities, it is possible that there are not enough chaperone molecules in the bacterium to fold the protein. Expressing the protein at lower levels might increase the amount of properly folded protein.
- The option B) is correct as urea should solubilize the protein and completely unfold it. Removing the urea slowly and gradually often allows the protein to refold. Presumably, under less crowded conditions, the protein should be able to refold into its proper conformation.
- The option C) is not correct as treating the aggregate with a protease, which cleaves peptide bonds, will probably solubilize the protein by trimming it into pieces that do not interact as strongly with one another; however, chopping up the protein will also destroy its enzymatic activity.
- The option D) is correct because overexpressing chaperone proteins might increase the amount of properly folded protein.
- The option E) is not correct as heating can lead to the partial denaturation and aggregation of proteins to form a solid gelatinous mass, as when cooking an egg white, and rarely helps solubilize proteins.
