In biphosphate is any salt of phosphoric acid in which only one of the hydrogen atom has been replaced by a metal ion whereas bisphosphate is a diphosphate and it has two phosphate groups attached to a sugar residue.

Phases of mitosis. Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our *** cells – sperm in males, eggs in females. During meiosis one cell divides twice to form four daughter cells. There are six stages within each of the divisions, namely prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis.

Guanosine triphosphate (GTP) is a guanine nucleotide containing three phosphate groups esterified to the sugar moiety. GTP functions as a carrier of phosphates and pyrophosphates involved in channeling chemical energy into specific biosynthetic pathways. GTP is involved in energy transfer within the cell. For instance, a GTP molecule is generated by one of the enzymes in the citric acid cycle. This is tantamount to the generation of one molecule of ATP, since GTP is readily converted to ATP with nucleoside-diphosphate kinase (NDK).

The Wobble hypothesis proposes that normal base pairing can occur between nitrogen bases in positions 1 and 2 of the codon and the corresponding bases (3 and 2) in the anticodon. Actually, the base 1 in anticodon can form non-Watson-Crick base pairing with the third position of the codon. The wobble effect is an effect caused by the redundancy found in the genetic code. Each amino acid is coded for by a 3 nucleotide sequence on the mRNA. ... Thus, each amino acid can be coded for by more than one codon. For any amino acid, the first 2 nucleotides in the codon are always identical.

Factors affecting the rate of Imbibition
- Nature of imbibant:Different types of organic substances have different imbibing capacities. Proteins have a very high imbibing capacity, starch has less capacity and cellulose is the weakest imbiber. That is why proteinaceous pea seeds swell more on imbibition than starchy wheat seeds
- Temperature:The rate of imbibition increases with the increase in temperature.
- Concentration of the solute: Increase in concentration of the solute decreases imbibition due to a decrease in the diffusion pressure gradient between the imbibant and the liquid being imbibed.
- Surface area of imbibant:The imbibition will be greater when the surface area of imbibant is larger.

Synapsis (also called syndesis) is the pairing of two homologous chromosomes that occurs during meiosis. It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them. Synapsis takes place during prophase I of meiosis. Chiasmata is the point of contact, the physical link, between two (non-sister) chromatids belonging to homologous chromosomes. The chiasmata become visible during the diplotene stage of prophase I of meiosis, but the actual "crossing-overs" of genetic material are thought to occur during the previous pachytene stage.

The cell cycle is a 4-stage process consisting of Gap 1 (G1), Synthesis, Gap 2 (G2) and mitosis. An active eukaryotic cell will undergo these steps as it grows and divides. After completing the cycle, the cell either starts the process again from G1 or exits the cycle through G0.

Cofactors are not proteins but rather help proteins, such as enzymes, although they can also help non-enzyme proteins as well. Examples of cofactors include metal ions like iron and zinc.
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Glycosidic bonds are the covalent chemical bonds that link ring-shaped sugar molecules to other molecules.
The phosphodiester bond is the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another, deoxyribose in DNA and ribose in RNA.

The mechanism by which an enzyme binds with the substrate to forward the reaction of producing products can be explained by Lock and key hypothesis and Induced fit mechanism.
Lock and Key hypothesis: This hypothesis was putforth by Emil Fischer in 1894. Enzyme has a special site called as active site. the conformation of this active site corresponds to the shape of the substrate which fits into the active site. Enzyme is the lock and substrate is the key. A particular substrate can only fit into active site of the enzyme to form the enzyme substrate complex. (ES complex) This intermediate complex is later broken to form enzyme and the products. Enzyme undergoes no change but helps in forwarding the reaction. This is called as lock and key hypothesis.
Induced-Fit mechanism: In this mechanism, the substrate wraps over the enzyme bringing about the change in the enzyme molecule. Here substrate determines the final shape of the enzyme. ES complex is formed after bnding. ES complex breaks to give rise to enzyme and products. Enzyme undergoes no change. Exactly to say the active site is modified during Enzyme-Substrate complex formation.
