The bacterium Methylophilus methylotrophus can use methanol and ammonia for protein synthesis. The glutamate dehydrogenase gene from E. coli was introduced into M. methylotrophus using recombinant DNA techniques. Under high ammonia conditions, the introduction of the glutamate dehydrogenase gene into M. methylotrophus resulted in an increase in protein yield. Select the statements that are reasonable explanations for the increased protein yield in the modified M. methylotrophus. Glutamate dehydrogenase catalyzes the formation of glutamate and glutamine in a two-step process. Both glutamate and glutamine play a key role in amino acid synthesis, thus an increase in levels of glutamate and glutamine increase protein synthesis. Glutamate dehydrogenase has a low affinity for NH^+_4, and can only catalyze the formation of glutamate from alpha-ketoglutarate and NH^+_4, when the concentration of NH^+_4 is high. Glutamate dehydrogenase has a high affinity for NH^+_4, thus the rate of glutamate synthesis increases exponentially under high ammonia conditions. Glutamate is the amino group donor for most transamination reactions involving amino acids, thus an increase in glutamate concentration increases protein synthesis.
Answer:
- Glutamate dehydrogenase has a low affinity for NH+4, and can only catalyze the formation of glutamate from alpha-ketoglutarate and NH+4, when the concentration of NH+4 is high.
- Glutamate is the amino group donor for most transamination reactions involving amino acids, thus an increase in glutamate concentration increases protein synthesis.
Explanation:
Glutamate dehydrogenase (GLDH) is an enzyme found in prokaryotic and eukaryotic cells, which is known to catalyze the reversible oxidative deamination of glutamate (Glu) to alpha-ketoglutarate and ammonia at the same time the oxidation of NADH to NAD. In bacteria, this enzyme (GLDH) is efficient only at high concentrations of the ammonium cation (NH4+), because it has a low affinity for NH4+. Moreover, transamination is a pathway that involves the transfer of an amino group from one amino acid to a ketoacid in order to form new amino acids (this reaction is responsible for the deamination of most amino acids). Glu is the donor of amino groups in most of the reactions catalyzed by enzymes involved in the transamination between an amino acid and an alpha-keto acid. In consequence, in presence of GLDH, a high concentration of Glu will increase the production of new amino acids and therefore also protein synthesis.

olecular diagnostic techniques that can help diagnose hemoglobin disorders such as hemoglobinopathies and thalassemias include a) biochemical separation, identification, and quantification of mixture components b) separation of macromolecules and their fragments, based on their size and charge c) DNA amplification, hybridization, and nucleotide sequencing d) The use of specific monoclonal antibodies
Answer:
The correct answer is - a) biochemical separation, identification, and quantification of mixture components.
Explanation:
Most hemoglobin disorders can be diagnosed by molecular diagnostic techniques such as protein-based techniques like electrophoresis and chromatography. Protein-based methods can diagnose early thalassemia disorders and hemoglobinopathies but in the case of α-thalassemia may be masked in the presence of β-thalassemia.
Molecular genetic testing plays a very important role in the biochemical separation of molecules or components, identification, and quantification of individuals carrying thalassemia and hemoglobinopathies traits and other hemoglobin disorders.

A red blood cell has an intracellular concentration of 300 mOsM of nonpenetrating solute. What best describes a solution containing 100 mM NaCl and 150 mM urea relative to the red cell?
The solution is hypertonic to a solution containing 100 mM NaCl and 150 mM urea relative to red blood cell.
The term "hypertonic" refers to a solution that has a higher concentration of solutes compared to another solution. In this case, the solution containing 100 mM NaCl and 150 mM urea has a higher concentration of solutes than the intracellular concentration of the red blood cell, which is 300 mOsM of nonpenetrating solute.
The concept of tonicity is important in understanding how solutions affect cells. When a solution is hypertonic to a cell, it means that there is a greater osmotic pressure outside the cell than inside. In this specific scenario, the hypertonic solution has a higher concentration of solutes (NaCl and urea) than the red blood cell's internal nonpenetrating solute concentration.
As a result, water molecules will tend to move from an area of lower solute concentration (inside the cell) to an area of higher solute concentration (outside the cell) in an attempt to equalize the concentration on both sides of the cell membrane. This movement of water out of the cell can lead to cell shrinkage or crenation, which occurs when the cell's volume decreases due to water loss.
In summary, the solution containing 100 mM NaCl and 150 mM urea is hypertonic to the red blood cell because it has a higher concentration of solutes than the cell's internal nonpenetrating solute concentration, leading to water movement out of the cell and potential cell shrinkage.

Identify and describe the protist that was responsible for the Irish potato famine of the 1840s.
A.) brown algae
B.) water mold
C.) Protoza
D.) slime mold
Answer:
B.) water mold
Explanation:
The water mold is a filamentous fungus like organisms that lives in brackish water, fresh water or wet soils. They are saprophytic, that is, they live on dead organisms. Their reproduction is usually by motile asexual spores (zoospores).The zoospores are of two types namely pear-shaped with apical flagella and kidney-shaped with two flagella on the concave side. Water mold are usually identified by their zoospores.

What processes found at a divergent boundary will help form the following rocks?
Answer:
B
Explanation:
What is a divergent boundary:
In plate tectonics, a divergent boundary is a linear feature that exists between 2 tectonic plates moving away from each other.
They can produce rifts, which become rift valleys.
Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that magma rises to fill.
Sedimentary rocks form due to deposition, and accumulation
Metamorphic rocks form in a transformation of existing rock to new rock in a process called metamorphism.
Igneous rocks form through the cooling and solidification of magma or lava.
When the filled gaps of magma cool off, it will produce igneous rocks.
why it is important that we have an understanding of geologic time
Answer:
Time is a very important variable in geology because the exact timing of spatially separated events allows us to reconstruct the surface and surface conditions of the ancient earth. Geologic time spans are considerably more difficult to comprehend than historical time spans because they are so incredibly long.
One reason is so that we can fully understand how geological processes that seem impossibly slow can produce anything of consequence. For example, we are familiar with the concept of driving from one major city to another: a journey of several hours at around 100 km/h. Continents move toward each other at rates of a fraction of a millimetre per day, or something in the order of 0.00000001 km/h, and yet, at this impossibly slow rate, they can move thousands of kilometres. Sediments typically accumulate at even slower rates — less than a millimetre per year — but still they are thick enough to be thrust up into monumental mountains and carved into breathtaking canyons.
Another reason is that for our survival on this planet, we need to understand issues like extinction of endangered species and anthropogenic (human-caused) climate change. Some people, who don’t understand geological time, are quick to say that the climate has changed in the past, and that what is happening now is no different. And it certainly has changed in the past. For example, from the Eocene (50 Ma) to the present day, Earth’s climate cooled by about 12°C. That’s a huge change that ranks up there with many of the important climate changes of the distant past, and yet the rate of change over that time was only 0.000024°C/century. Anthropogenic climate change has been 1.1°C over the past 100 years, and that is 45,800 times faster than the rate of natural climate change since the Eocene.
