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
Adenine is a heterobicyclic aromatic compound with a purine backbone that, as an organic nucleic base, forms one of the basic building blocks of genetic information in DNA and RNA along with three other bases. In addition, adenine in the form of a nucleoside or nucleotide plays an important role in metabolism as NAD, FADH2 … Adenine: Function & Diseases
In the salvage pathway, a new biomolecule is synthesized from the degradation products of a biomolecule. The salvage pathway is also known as the salvage pathway and is, in a sense, a form of recycling within metabolism. What is the salvage pathway? Salvage pathway refers firstly to the general form of this recycling within metabolism … Salvage Pathway: Structure, Function & Diseases
Cytidine belongs to the nucleosides and is composed of the nucleic base cytosine and the sugar ribose. It forms a base pair with guanosine via hydrogen bonding. It also plays a central role in pyrimidine metabolism. What is cytidine? Cytidine represents a nucleoside composed of cytosine and ribose. The nitrogen base cytosine is involved in … Cytidine: Function & Diseases
Nucleic bases are the building blocks that, in their phosphorylated nucleotide form, make up the long chains of DNA and RNA molecules. In DNA, which forms rope ladder-like double strands, the 4 occurring nucleic bases form tight pairings with the respective complementary base via hydrogen bonds. The nucleic bases consist of either a bicyclic purine … Nucleic Bases: Function & Diseases
Nucleic acids are composed of a string of individual nucleotides to form macromolecules and, as the main component of genes in cell nuclei, are carriers of hereditary information, and they catalyze many biochemical reactions. The individual nucleotides each consist of a phosphate and a nucleic base moiety as well as the pentose ring molecule ribose … Nucleic Acids: Function & Diseases
Splicing represents a crucial process during transcription in the nucleus of eukaryotes, in which mature mRNA emerges from pre-mRNA. In this process, introns that are still present in the pre-mRNA after transcription are removed, and the remaining exons are combined to form the final mRNA. What is splicing? The first step in gene expression is … Splicing: Function, Tasks, 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
Xanthine is formed as an intermediate in the breakdown of purine nucleotides to uric acid. Thus, it represents a central molecule in the context of nucleic acid metabolism. When xanthine degradation is disturbed, so-called xanthinuria occurs. What is xanthine? Xanthine represents an intermediate product in purine degradation in the organism. The most important starting compounds … Xanthine: Function & Diseases
Guanine is an important nitrogen base and has a central role in nucleic acid metabolism in the organism. It can be synthesized in the body from amino acids. However, due to the high energy expenditure of this reaction, its recovery often occurs via the salvage pathway. What is guanine? Guanine is one of the five … Guanine: Function & Diseases
