Brainstorm how you could use recombinant DNA technology to make normal E. coli bacterial cells glow green.

DiKsa [7]

Answer:

In order to make E. coli bacterial cells glow green, we need to insert a gene that can be translated into the <u>green fluorescent protein.</u> This gene is well-known as <u>gfp</u> and can be inserted either in the DNA or plasmid of the bacteria. The genome insertion procedure would follow the conventional method where the DNA will be first cut using restriction enzymes and then would be ligated. This approach has been extensively applied to test the fate of bacteria in the environmental systems.

A schematic diagram on insertion of gfp in the plasmid of bacteria is shown in the figure. The left side diagram shows that gfp is inserted and right side figure shows glowing bacteria in the presence of UV.

Describe the process of photosynthesis. What ingredients does a plant need in order to complete photosynthesis? After photosynth

forsale [732]

Answer:

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds, Three main ingredients are required for photosynthesis: water, carbon dioxide, and light. Plants use light energy from the sun to convert six water molecules (6 H2O) and six carbon dioxide molecules (6 CO2) into a molecule of glucose and six molecules of oxygen, Carbohydrates(glucose) and Oxygen is the end product.

DNA ligase<span> can be described as a DNA-joining enzyme. It has a possibility to link two pieces of DNA if they have the matching ends, using ATP as an energy source. As a result, unbroken molecule of DNA is formed.</span> It is used in recombinant DNA experiments, for example,<span> to insert genes and other pieces of DNA into plasmids.</span></span>

comparison of recombinant transforming growth factor-beta-2 and placebo as an adjunctive agent for macular hole surgery.

Semmy [17]

Transforming growth factor (TGF-), a cytokine with a wide range of functions, is crucial for cancer, angiogenesis, wound healing, and immune modulation. The TGF-1 isoform, which has potent anti-inflammatory effects and is a key regulator of the immune response, is produced by immune system cells.

A placebo can nevertheless make a patient feel better even when it has no components that will have a positive impact, which corresponds to the word's Latin roots and its meaning of "I shall delight." The word "placebo" has a long history of denoting "flatterer" or "to flatter" before it became associated with medicine.

<h3>What is Recombinant transforming growth factor-beta-2 ?</h3>

Transforming growth factor beta-2 (TGF-2) protein production is controlled by the TGFB2 gene. This protein is present in every cell of the body and is necessary for development both during pregnancy and after birth. TGF-2 interacts to receptor proteins on the surface of cells to perform its actions.

A person experiences the placebo effect when their physical or mental health seems to get better after receiving a placebo or "dummy" treatment. A treatment that seems to be real but is intended to have no therapeutic benefit is referred to as a placebo. The Latin word for placebo means "I will please."

<h3>What is Placebo ?</h3>

A placebo is a phony drug or procedure that is intended to have no known therapeutic benefit. Inert medications, inert injections, sham operations, and other treatments are frequently used as placebos.

Pure or inactive placebos, such sugar pills or saline injections, are one of two forms of placebos. Pure or active placebos, such as giving a patient a vitamin when they don't need it or an antibiotic for a viral infection.
