Biochemistry

The reaction that breaks the bonds between atoms within a polymer chain is called "scission". The bonds between chains of monomers, if they exist at all, are not chemical bonds and are broken by thermal motion.

*****It is actually called hydrolysis. Hydrolysis is a chemical process in which a molecule is separated into two parts by adding a molecule of water.****

DNA paternity testing works by comparing the DNA of the mother and child. The traits not apparent in the mother's DNA have to come with the father. Then, the DNA of the alleged father and child are compared. If the father has the missing traits, he may be the father.

In a dominant-recessive allele relationship, the dominant allele will be expressed phenotypically over the recessive allele. This means that even if an organism carries one dominant and one recessive allele for a particular trait, the dominant allele will determine the observable characteristic.

Carbon has some very important properties. It forms four bonds, and that is the highest number of bonds that any element forms, which gives it the capability of forming more complicated types of molecules than most other elements. There are, of course, other elements in group 4, that also form four bonds, such as silicon. However, carbon is the lightest element in that group, as as you go down the periodic table to heavier elements in that group, you get lower electronegativity, or in other words more metallic type of bonding, as compared to the non-metallic type of bonding that carbon forms, and this is significant because carbon can form moderately strong bonds with various elements such as hydrogen, oxygen, and nitrogen (etc.) but the more metallic elements of group 4 form stronger and more permanent bonds (compare the properties of carbon dioxide and silicon dioxide - quite a difference!). So as it turns out, only carbon gives us the versatility that is needed to form the basis of biochemistry. There can be no life without carbon. It is not for nothing that Star Trek refers to humans as a carbon based life form.

The linkage in nucleotides is called a phosphodiester bond. It forms between the phosphate group at the 5' carbon of one nucleotide and the hydroxyl group at the 3' carbon of another nucleotide in a DNA or RNA molecule.

Amino acids are called alpha amino acids because the amino group (-NH2) is attached to the alpha carbon atom in the molecular structure of the amino acid. This alpha carbon is the carbon atom next to the carboxyl group (-COOH) in the amino acid molecule.

The zygote is dormant initially because it needs time to adjust its metabolic activities and undergo cell division. This process allows for the development of the early embryo before it starts active growth and implantation in the uterus.

The xanthoproteic test involves nitration of aromatic amino acids in proteins, which may not always be specific for proteins as other compounds containing these amino acids can give false positive results. The Millon-Nasse test is based on the reaction of phenol groups in proteins, which can also react with other substances containing phenol groups, leading to false positive results. Overall, these tests lack specificity and can give inaccurate results when used to examine proteins.

The substance that breaks down polypeptides in the small intestine is an enzyme called trypsin, which is produced by the pancreas. Trypsin functions to cleave peptide bonds between specific amino acids, resulting in the breakdown of polypeptides into smaller peptides and eventually into individual amino acids for absorption by the body.

Acetyl-CoA is a common molecule generated during the breakdown (catabolism) of both fat and glucose. Acetyl-CoA is a key intermediate that enters the citric acid cycle to generate energy through the production of ATP.

After a biochemical reaction, the enzyme remains unchanged and is free to catalyze more reactions. Enzymes are not consumed in the reaction and can be used repeatedly, making them efficient catalysts.

Sexual reproduction is great asset to the nature. In asexual reproduction you will get the exact replica of the original organism. You will get the new type of organism by chance only. In sexual reproduction, you get the new types of organism, almost invariably. Half of the chromosomes come from the female and half of the chromosomes come from the male. That happens through the process of meiosis. There is random assortment of the chromosomes. You can have numerous types of progeny. The better progeny is produced. so the nature is doing only one business. Nature wants better and still better progeny. After you produce the offsprings, nature loses interest in you.

The enzyme responsible for converting glucose to fructose is glucose isomerase. It catalyzes the reversible isomerization of glucose to fructose. This enzyme is commonly used in the production of high-fructose corn syrup.

Digestion of protein starts from stomach. In stomach the proteolytic enzymes such as pepsin, trypsin, chymotrypsin are produced and act of proteins derived from food. But in general, an enzyme can break down proteins anywhere (in lab environment too) if there is optimal condition (such as buffer, pH) is provided.

In science, alpha typically refers to the first letter of the Greek alphabet. It is commonly used in various contexts, such as representing the symbol for angular acceleration, alpha particles in nuclear physics, or significance level in statistical hypothesis testing.

The electrons in a conductor will support the movement of electric current. A conductor is defined as a material with a number of electrons in its makeup that are actually in what is called the conduction band. The conduction band is an energy level where electrons must be to permit conduction in a material. If the minimum energy in the conduction band in a material is such that a lot of electrons in that material are already at or above that level, then these electrons will be available to support current flow. Remember that electron current flow is moving electrons, and it is not about sending an electron into a conductor, like a wire, at one end and getting that same electron out at the other. It is about sending a bunch of them in at one end, and all the electrons already in the conductor move over and a bunch come out the other end. The electrons already in the conduction band within the conductor support current flow in this way.

There are two mechanisms as related to above. Firstly, the removal of All Introns occurs - via the Spliceosome -, and then a "poly AAAAAAA" tail is attached to the [edited] mRna transcript just before its export to the cytoplasmic Ribosomes.

There is no single answer to the question, because there are many known hormones that can be tested. A Hormone is any chemical released by a Gland (any tissue that secretes chemical messages) that affects a different tissue in the body. Hormones control the body's growth functions, as well as the male and female reproductive cycles, immune responses, male and female sexual arousal (arousal not the response), energy, and even the flight or fight response. The most commonly known hormone is Thyroid Stimulating hormone. The most commonly prescribed hormone is the combination of estrogen/progesterone used for birth control.

Human chorionic gonadotropin (hCG) is the hormone most useful in determining whether a woman is pregnant. This hormone is produced by the placenta shortly after implantation and its levels rise significantly in the early stages of pregnancy. Pregnancy tests detect hCG in a woman's urine or blood to confirm pregnancy.

Penicillin acylase is also known as penicillin G acylase or penicillin amidase.

Amino acids are joined together by peptide bonds to form proteins. Peptide bonds are formed through a condensation reaction between the amino group of one amino acid and the carboxyl group of another amino acid.

The energy transformation that changes food into energy for physical activity like playing soccer is known as chemical energy conversion. When you eat food, your body breaks it down into nutrients which are then converted into energy through a process called cellular respiration. This energy is used by your muscles to perform activities like running, kicking the ball, and playing soccer.
