The study of genetic variation in populations depends on heterozygosity, the state of possessing two distinct alleles at a location. In fact, Mendel's original research focused on determining how the two alleles present in heterozygous individuals at certain loci or combinations of loci are passed down to progeny. Our knowledge of the roles of mutation, natural selection, genetic drift, and migration in sustaining heterozygosity in populations was developed by Sewall Wright's groundbreaking theoretical work beginning in the 1920s (see Maintenance of Heterozygosity). Heterozygosity in natural populations was difficult for early empirical population geneticists to identify and quantify. Since all living things share the same basic molecular biology, population geneticists have been able to detect heterozygosity in all organisms since the 1960s thanks to the advent of biochemical tools.

The discovery of life based on silicon would imply that carbon is not central to life as previously supposed.

We know that carbon is an element that we can find in group fourteen of the periodic table. Carbon is an element that has been said to be very important to life. We know that all the living things that can be found on earth are composed of the element that we call carbon. As such a study of the chemistry of the life on earth is essentially almost the same as the study of carbon.

So much so that the element carbon can now be seen as the only element that could be said to be fundamental to life. This is the position that has stood unchallenged for so many years.

Substrate level phosphorylation is seen in both glycolysis and the Krebs cycle.

What is Phosphorylation?

Phosphorylation is a biochemical process in which a phosphate group is added to a molecule, usually a protein or other organic molecule. This process is important in many cellular processes, such as cell signaling, metabolism, and gene expression. Phosphorylation typically occurs when a protein is activated or deactivated by a specific chemical signal, such as a hormone.

What is the Krebs cycle?

The Krebs cycle, also known as the citric acid cycle or tricarboxylic acid (TCA) cycle, is a series of chemical reactions that takes place in the mitochondria of cells. It is the central metabolic pathway of cellular respiration, where energy from carbohydrates, fats, and proteins is converted into adenosine triphosphate (ATP) molecules, the primary energy source of the cell. The Krebs cycle involves the oxidation of acetyl-CoA to carbon dioxide and the reduction of NAD+ to NADH.

The volume of blood the heart pumps in a minute is measured in liters/minute and is called cardiac output. Logic dictates that cardiac output is equal to the sum of the stroke volume and the number of beats per minute (heart rate).

When calculating stroke volume, end-systolic volume—the amount of blood in the ventricle at the end of a beat—is subtracted from the volume of blood right before the beat using measurements of ventricular volumes from an echocardiography (called end-diastolic volume).

End-diastolic volume minus end-systolic volume is the definition of stroke volume, and cardiac output is the stroke volume multiplied by the heart rate.

The ion channels' pore-forming transmembrane domains hydrophobic alpha-helices.

By using infrared spectroscopy, the structure of the pore-forming transmembrane region of the Torpedo nicotinic acetylcholine receptor has been studied.

Affinity-purified receptors treated with proteinase K or proteinase pronase have their extramembranous domains (about 75 percent of the protein mass) digested, leaving behind hydrophobic membrane-imbedded peptides that range in size from 3-6 kDa and are immune to peptide (1)H/(2)H exchange.

The transmembrane domain preparations' infrared spectra show reasonably strong and symmetric amide I and amide II band contours, accordingly centred about 1655 and 1545 cm(-)1 in (1)H(2)O and (2)H(2)O.

The amide I band is extremely reminiscent to the amide I bands seen in the spectra of alpha-helical proteins, including myoglobin and bacteriorhodopsin, which lack beta structure and display far less beta-sheet character than seen in proteins with a lesser as 20% beta sheet.

With the residual peptides presumably acquiring prolonged and/or turn structures at the bilayer surface, curve-fitting predicts that 75–80% of the peptides have an alpha helical nature.

Transmembrane alpha-helices aligned perpendicular to the surface of the bilayer are aligned with infrared dichroism spectra. The nicotinic receptor, the most extensively researched ligand-gated ion channel, is thought to have five bundles of four transmembrane alpha-helices in its transmembrane domain.
