All domestic mammals have seven cervical vertebrae.
Answer:
The correct answer is 3 prime OH.
Explanation:
The joining of nucleotides takes place by a condensation reaction, which discharges a small, stable molecule. Unlike carbohydrates, proteins, and lipids, the molecules, which is discharged is not water, however, a pyrophosphate, that is, two phosphate groups combined together.
In the polymerization of DNA, a phosphodiester bond is formed between a free 5 prime phosphate group at one terminal and a free 3 prime hydroxyl group at the other end. The naming of these sequences is done from 5 prime to 3 prime.
Answer:
It is expected to observe the immunoprecipitation of the GST-tagged KinY complex, thereby indicating the role of RegX in the mechanism of cytoskeletal reorganization.
Expanation:
Western blot is a technique widely used in molecular biology laboratories in order to identify proteins and also to quantify their expression levels. This technique is useful to detect proteins with high specificity, in this case the technique has been used for the detection of an immunoprecipitated (i.e., GST-tagged KinY complex) in order to confirm the role of the upstream protein RegX in cytoskeletal organization.
Answer: May occur in response to growth factors
Explanation:
Hyperplasia is increased cell production in a normal tissue or organ. Hyperplasia may be a sign of abnormal or precancerous changes. This is called pathologic hyperplasia.
Pathologic hyperplasia can occur in response to hormones and growth factors (for example in endometrial hyperplasia, the hyperplasia caused by excessive hormonal stimulation or growth factors acting on target. Thus, patients with hyperplasia of the endometrium are at increased risk for developing endometrial cancer.)
Hyperplasia is also an important response of connective tissue cells in wound healing, in which proliferating fibroblasts and blood vessels aid in repair.
Under normal circumstances, growth factors are responsible for the hyperplasia. Stimulation by growth factors is also involved in the hyperplasia that is associated with certain viral infections, such as papillomaviruses, which cause skin warts and several mucosal lesions composed of masses of hyperplastic epithelium.
Other important concepts to note:
Dysplasia refers to abnormal changes in the size, shape, and organization of mature cells. Compensatory hyperplasia enables organ regeneration and is a normal process: hyperplasia is not normal. Pathologic hyperplasia increases cell number. Hypertrophy is an increase in the size of cells and consequently in the size of the affected organ.
