Answer:
Viruses can be used to insert genetic material into cells during gene therapy
Explanation:
Gene therapy is a process used to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.
A gene that is inserted directly into a cell usually does not function. Instead, a carrier called a vector is genetically engineered to deliver the gene. Certain viruses are often used as vectors because they can deliver the new gene by infecting the cell. The viruses are modified so they can't cause disease when used in people.
<span>A. Hershey and Chase used bacteriophages to confirm that DNA was the genetic material in genes.
</span>According to the central dogma of molecular biology, the process of protein synthesis in living organisms follows the order: DNA →RNA→ Protein.Information for synthesis of a particular protein is copied (transcribed) from DNA onto mRNA in a process called transcription, in the cell nucleus.<span>mRNA (messenger RNA) leaves the cell nucleus and enters the cytoplasm where it attaches to a ribosome. tRNA (transfer RNA) begins to decode (translate) the information on the attached mRNA in a process called translation and fetches amino acids corresponding to this information from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are joined together into a chain and thus the protein is formed.</span>
An understanding of anatomy is key to the practice of health and medicine
It is caused by the atmosphere of the Earth. It is due of the scattering of light by the atmosphere. When the moon is near the horizon, the moonlight must pass through much more atmosphere than when the moon is directly overhead.
Answer:
2. Information can be stored for future recovery.
3. Digital signals can be transmitted over long distances.
Explanation:
This world is moving towards digitalization. The digital signals are able to transmit the data over long distance. This has squeezed the world information and the data are run to distant places within seconds. The information on digital signals can be stored for later use.
