What functions do the chromosomes have? The chromosome, as the organizational unit of our genetic material, serves primarily to ensure an even distribution of the duplicated genetic material to the daughter cells during cell division. For this purpose, it is worthwhile to take a closer look at the mechanisms of cell division or the cell … What functions do the chromosomes have? | Chromosomes
What is the normal set of chromosomes in humans? Human cells have 22 sex-independent chromosome pairs (autosomes) and two sex chromosomes (gonosomes), so a total of 46 chromosomes make up one set of chromosomes. Autosomes are usually present in pairs. The chromosomes of a pair are similar in shape and sequence of the genes and … What is the normal set of chromosomes in humans? | Chromosomes
What is a chromosomal aberration? The structural chromosomal aberration basically corresponds to the definition of chromosomal mutation (see above). If the amount of genetic material remains the same and is only distributed differently, this is called a balanced aberration. This is often done by translocation, i.e. the transfer of a chromosome segment to another chromosome. … What is a chromosomal aberration? | Chromosomes
What is a chromosome analysis? Chromosomal analysis is a cytogenetic method used to detect numerical or structural chromosomal aberrations. Such an analysis would be used, for example, in cases of immediate suspicion of a chromosomal syndrome, i.e. malformations (dysmorphies) or mental retardation (retardation), but also in infertility, regular miscarriages (abortions) and also certain types of … What is a chromosome analysis? | Chromosomes
Phosphates are a series of chemical compounds that contain phosphorus. For example, they are found in adenosine triphosphate (ATP) – the primary energy source in the body. Increased phosphate concentration in the blood is associated with kidney disorders, among other things. What are phosphates? Phosphates are formed from orthophosphoric acid. As salts of orthophosphoric acid, … Phosphates: Function & Diseases
Synonym Microscopic Anatomy Definition – What is histology actually? The word histology is composed of the word “histos”, which means “tissue” in Greek and the Latin word “logos” for “doctrine”. In histology, i.e. “tissue science”, people use technical aids such as a light microscope in everyday life in order to recognize the structure of various … Histology
Frozen section analysis This is necessary if the surgeon needs information about the tissue removed during an operation in order to decide on the course of the procedure. For example, a small malignant tumor is removed from the kidney. Now a quick incision is required to see whether the tumor has been completely removed or … Frozen section analysis | Histology
Nucleases are enzymes whose function is to degrade nucleic acids such as ribonucleic acid or deoxyribonucleic acid. This is referred to as complete or partial digestion of the substrate. What are nucleases? Nucleases are generally responsible for the degradation of nucleic acids. In this process, the nucleic acid can be degraded from the ends of … Nucleases: Function & Diseases
Nucleic acid metabolism involves the assembly and disassembly of the nucleic acids DNA and RNA. Both molecules have the task of storing genetic information. Disturbances in the synthesis of DNA can lead to mutations and thus to changes in genetic information. What is nucleic acid metabolism? Nucleic acid metabolism involves the assembly and disassembly of … Nucleic Acid Metabolism: Function, Role & Diseases
Pseudouridine is a nucleoside that is a building block of RNA. As such, it is primarily a component of transfer RNA (tRNA) and is involved in translation. What is pseudouridine? Pseudouridine is a basic component of tRNA and consists of two building blocks: the nucleic base uracil and the sugar β-D-ribofuranose. Biology also refers to … Pseudouridine: Function & Diseases
A nucleotide is a basic building block of ribonucleic acid (RNA) or deoxyribonucleic acid (DNA) that has a base, sugar, or phosphate component. In cells, nucleotides have vital functions and are involved in hormonal signal transduction or energy production, for example. What are nucleotides? Nucleotides are the basic building blocks of RNA and DNA. They … Nucleotides: Function & Diseases
Waardenburg syndrome is a congenital condition that medical science classifies under leucism and divides into four different types. Typical signs include deafness, malformations, and pigmentary abnormalities. Because Waardenburg syndrome is a genetic disorder, it is not causally treatable. What is Waardenburg syndrome? Waardenburg syndrome is a type of leucism that lay people often confuse with … Waardenburg Syndrome: Causes, Symptoms & Treatment
