The original base sequence of DNA is : CAG TTA CCA. If the amino acid sequence that results from translation of this DNA base sequence is: valine-tyrosine-glycine, what mutation occurred in the DNA? Explain
A. An addition mutation occurred
B. A deletion mutation occurred
C. A substitution mutation occurred
D. A mutation did not occur.

Answer:

Explanation:

a.

Phosphofructokinase-1, also known as the glycolysis stimulator, is among the most important glycolysis regulatory enzymes. It's an apoptotic enzyme with effectors (activators/inhibitors) that control its activity. Fructose 6-phosphate and ATP are converted to fructose 1,6-bisphosphate and ADP by PFK-1.

Suppose the serine in PFK's active site is substituted with aspartic acid, the enzyme's active site would be devoid of phosphorylation sites. The enzyme PFK contributes to the transferase family since it has kinase activity. It serves as an acceptor by transferring phosphorus groups to an alcohol group (serine).

Insulin stimulates protein phosphatase, which eliminates the phosphate group from the serine residue, stabilizing the kinase role and promoting F26BP formation. The phosphorylation reaction will not take place provided the serine is substituted with aspartic acid. Therefore, the PFK's kinase activity will be lost. Similarly, F26BP will not form PFK, and it will not be aborted in the future.

b.

Their decline reveals that:

F26BP increases the overall net flow of glucose by glycolysis modulates PFK production and induces Fructose 1,6 bis phosphatase, which also catalyzes the glycolysis reverse process.

Fructose-2,6-bisphosphate transcriptionally activates the rate-limiting process of glycolysis catalyzed by PFK 1.

Increased levels of Fru-2,6-P2 located in the liver raise PFK1's propensity and resistance for fructose 6 phosphate while lowering its affinity for its' inhibitors ATP and citrate.

Fructose 2,6-bisphosphate supersedes the inhibition of ATP and promotes greater sensitivity of the eukaryotes to be regulated by hormones (glucagon and insulin).

The uneven heating of the earth's surface is one of the main variables affecting the circulation of the atmosphere globally along with  seasonal variations in precipitation and temperature and Earth turning on its axis.

The state of the atmosphere is referred to as the weather, and can be described in a number of different ways, including the degree to which it is hot or cold, wet or dry, quiet or stormy, clear or cloudy. The troposphere, the lowest layer of the Earth's atmosphere, is where the majority of meteorological events take place. The stratosphere is the next layer up from the troposphere. The term "weather" is used to describe the temperature, precipitation, and other characteristics of the atmosphere on a day-to-day basis.

Variations in air pressure, temperature, and moisture from one location to another are the primary contributors to a day's weather. These disparities can be attributed to the fact that the angle at which the Sun is positioned at any given location varies with latitude. The vast temperature difference between the polar and tropical air masses is what gives rise to the biggest scale atmospheric circulations.

Answer:

Transcription and translation are the means by which cells read out, or express, the genetic instructions in their genes. Because many identical RNA copies can be made from the same gene, and each RNA molecule can direct the synthesis of many identical protein molecules, cells can synthesize a large amount of protein rapidly when necessary. But each gene can also be transcribed and translated with a different efficiency, allowing the cell to make vast quantities of some proteins and tiny quantities of others (Figure 6-3). Moreover, as we see in the next chapter, a cell can change (or regulate) the expression of each of its genes according to the needs of the moment—most obviously by controlling the production of its RNA.

Explanation:

RNA is a molecule with characteristics and a role similar to DNA. RNA necessary for DNA to fulfill its function because RNA is needed to bring the code to protein-producing organelle.

t RNA is the transfer RNA which brings up messages to code for a particular type of protein via the message carried by the m RNA after which the amino acid chains start gets forming.

A triplet codon is produced where three of the nucleotides bind together to form a particular  type of a protein.

Rna has a machinery for the messages transferred as  it will channel information to tRNA  where on the ribosomal unit it will start synthesising a particular kind of amino acid.

RNA contains the instructions for how an organism functions and DNA contains the instructions for creating the physical structures of an organism.

Therefore, RNA  is important as well.

Answer:

The correct answer is - punctuated equilibrium.

Explanation:

The phenomena represent punctuated equilibrium, according to which the new well-defined species appear suddenly and quickly. These species remain unchanged for a long time as they occur because of mutations in genes.

This phenomenon suggests that once it made in the fossil record the population becomes stable for a long time until they become extinct and have to adapt to the changes take place to survive.

Asexual reproduction in plants is advantageous when plants are well adapted to the environment that is present in Option H, as plants that are well adapted to their environment are more likely to produce offspring that can thrive in that environment as well.

Asexual reproduction allows for the efficient production of genetically identical offspring without the need for finding a mate or investing energy in gamete production, and this can be particularly advantageous in stable environments where there is little change and plants can thrive without the need for genetic diversity. In plants, asexual reproduction can occur through various means, including vegetative reproduction, where new plants are produced from parts of the parent plant such as stems, leaves, or roots.

Hence, asexual reproduction in plants is advantageous when plants are well adapted to the environment that is present in Option H.

It's all a part of a very complex cycle… one thing feeds into another making an almost infinite loop.

The problem with the existence of humans is that we are interrupting the cycle by pumping out carbon dioxide at unsustainable rates. Nitrogen based fertilizers are causing massive algal blooms causing fish die offs on unprecedented scales… but I digress.

Answer:

the release of heat by the formation of hydrogen bonds.

Explanation:

Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).

Condensation can be defined as a process which typically involves the change in the physical state of matter from the gaseous phase into a liquid phase i.e water changing from gas (vapor in the air) into a liquid form.

Temperature usually increase when water condenses. This phenomenon is as a result of the release of heat (exothermic reaction) by the formation of hydrogen bonds in water i.e hydrogen-hydrogen bond in water molecules formed by the chemical elements; oxygen and hydrogen.
