Cancer is the typical result of cell division
Answer:
<em>The correct option is D) need to be aware that if any of his garlic plants became diseased, it could very likely infect the entire crop</em>
Explanation:
If cloves from a bulb are taken and grown, then the plants formed will be identical to each other. As a result, there will be no genetic varieties in the garlic plants being produced. Hence, when a diseases eradicates, it will affect the entire plants of the garden as they would be genetically identically, Variations would have allowed some of the plants to be resistant for the disease and hence some of the plant species could be saved by genetic variations.
Answer:
All cells contain genetic information in the form of DNA molecules. ... Empirical evidence is required to differentiate between cause and correlation and to make claims about the role of DNA and chromosomes in coding the instructions for the characteristic traits passed from parents to offspring.
Explanation:
Answer: Living things are placed into groups based on both structural and functional similarities. For example, bacteria are prokaryotic cells, which means they lack a true nucleus. Cytoplasm Functions. Some of these processes include protein synthesis, the first stage of cellular respiration (known as glycolysis), mitosis, and meiosis. In addition, the cytoplasm helps to move materials, such as hormones, around the cell and also dissolves cellular waste.
Explanation:
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.
