In 1973, Stanley Cohen and Herbert Boyer inserted a gene from an African clawed frog into a bacterium. The bacterium then began producing a protein directed by the gene from the frog.
Which is considered a transgenic organism?

Answer:

Point mutations can have one of three effects. First, the base substitution can be a silent mutation where the altered codon corresponds to the same amino acid. Second, the base substitution can be a missense mutation where the altered codon corresponds to a different amino acid. Or third, the base substitution can be a nonsense mutation where the altered codon corresponds to a stop signal.

A frameshift variant occurs when there is an addition or loss of nucleotides that shifts the grouping and changes the code for all downstream amino acids. The resulting protein is usually nonfunctional. Insertions, deletions, and duplications can all be frameshift variants.

The nucleic acid molecule that allows transmission of genetic material and protein synthesis is called messenger RNA. This messenger RNA serves as an intermediate for protein synthesis because DNA is protected in the nucleus.

What is translation?

process by which cell makes proteins using the genetic information carried in messenger RNA (mRNA).

There are two main types of nucleic acids. two types are DNA or deoxyribonucleic acid, and RNA or ribonucleic acid. Both of these molecules serve function in gene expression.

RNA carries genetic information that is translated by ribosomes into various proteins necessary for the cellular processes. mRNA, rRNA, and tRNA are the three main types of RNA involved in the protein synthesis. RNA also serves as primary genetic material for viruses.

Translation, second step in getting from a gene to a protein, takes place in the cytoplasm.

Explanation:

A mutation affects nucleic acids because they can alter the genetic code, meaning the sequence of nucleotides. This alteration can change the amino acid sequence for a protein.

Cells can increase their surface area by folding the plasma membrane. Total cell surface area should increase when a cell divides into two daughter cells.

There are two illustration of membrane supply that support cell division:

(1) unfolding of small surface membrane reservoirs such as microvilli and folds, and (2) exocytosis of intracellular vesicles.

As the cell radius increases, the surface area increases as the radius squared, but the volume increases as the radius cubed (much faster).

Increasing the surface area of ​​the cell increases the amount of material that diffuses into the cell. As volume and surface area increase, volume increases more rapidly, so for every doubling of cell volume, the surface area available for uptake is halved.

Answer:

The force of air resistance clearly depends on the velocity of an object moving through the air: the larger the speed, the larger the drag force.

Explanation:

As learned above, the amount of air resistance depends upon the speed of the object. ... Thus, more massive objects fall faster than less massive objects because they are acted upon by a larger force of gravity; for this reason, they accelerate to higher speeds until the air resistance force equals the gravity force.

Answer: The force of air resistance clearly depends on the velocity of an object moving through the air: the larger the speed, the larger the drag force.

Explanation:

During cellular respiration, stored chemical energy is gradually released in a series of enzyme-assisted reactions. Burning a log releases the stored chemical energy rapidly as heat and light.

The energy produced by cellular respiration is in the form of chemical bond energy. The energy produced when a log of wood is burned is mainly heat or heat energy and some light energy.

The third phosphate bond of adenosine triphosphate (ATP) is a high-energy bond. It is used to provide energy for metabolic reactions and perform tasks such as muscle contraction. Energy is the ability to execute work. It is electricity obtained from a physical or chemical source and used to provide heat or light or to do work. Forms of energy include chemical, thermal, mechanical, electrical and nuclear energy. Energy can be transformed from one mode to another.

The respiratory system is supported by the circulatory system, which carries blood to and from the lungs. The circulatory system is made up of the heart and blood arteries.

The circulatory system assists in moving nutrients and oxygen from the lungs to the body's tissues and organs. Additionally, it aids in the removal of trash and carbon dioxide. Blood and oxygen are moved throughout the body through the circulatory system and respiratory system. The respiratory system, which includes the lungs and airways, brings oxygen into the body and expels carbon dioxide through breathing, whereas the cardiovascular system, which includes the heart and blood vessels, pumps oxygen-rich blood from the lungs to the respiratory system rest of the body through the circulatory system.

Proto-oncogenes are rates that regularly aid cells to grow and split to create new cells or to assist cells with remaining alive. At the point when a proto-oncogene transforms (changes) or there are an excessive number of duplicates of it.

The two duplicates of a particular cancer silencer quality pair should be transformed to prompt an adjustment of cell development and growth arrangement to occur. Consequently, cancer silencer qualities are supposed to be passive at the cell level. Transformations in cancer silencer qualities are frequently procured.

Proto-oncogenes are a gathering of qualities that make ordinary cells become carcinogenic when they are transformed (Adamson, 1987; Weinstein and Joe, 2006). Transformations in proto-oncogenes are ordinarily predominant in nature, and the changed rendition of a proto-oncogene is called an oncogene.

Because the genetic determination of coat color in calico cats is linked to the X chromosome, calico cats are almost always female, with one color associated with the maternal X chromosome and the other. is associated with the paternal X chromosome.

The calico cat displays a mixed color of red and black, depending on which of her two X chromosomes is inactivated. The allele that codes for orange hair color is dominant, while the black color allele is recessive. Out of 3,000 calico cats born, only one is male. If the male cat is a calico cat (calico), it means she has two X chromosomes and she has one Y chromosome. This is a chromosomal mutation recognized as XX male syndrome.

According to the animation, the Krebs cycle is the only one where six electron carriers are decreased.

The electrons are employed to convert an oxygen molecule into oxygen ions at the system's conclusion. Water is created when hydrogen ions (protons) from the surrounding medium are drawn to the additional electrons on oxygen ions.

An oxygen molecule serves as the final electron acceptor in aerobic respiration, or the one with the highest or most positive redox potential, at the end of the ETS (O2). This is diminished.
