Zygomycota

Zygomycota

Let’s know about Zygomycota. Zygomycota , or zygote fungi , are a former division or phylum of the fungal kingdom . The members are now part of two phyla Mucoromycota and Zoopagomycota. [1] About 1060 species are known. [2] They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material. …

Mucorales

Mucorales

The Mucorales are the largest and best studied of the order zygomycete fungi . Members of this sequence are sometimes called pin molds . The term mucormycosis is now preferred for infections caused by molds belonging to the order Mucorales. classification The order includes: 11 families , 56 genera , and about 300 species . …

Thyrotropin Releasing Hormone

Thyrotropin Releasing Hormone

Let’s know about Thyrotropin Releasing Hormone. Thyrotropin Releasing Hormone ( TRH ) is a hypophysiotropic hormone produced by neurons in the hypothalamus that stimulates the release of thyroid stimulating hormone (TSH) and prolactin from the anterior pituitary. TRH has been used clinically for the treatment of spinocerebellar degeneration and disturbances of consciousness in humans. [1] …

Melanocyte Stimulating Hormone

Melanocyte Stimulating Hormone

Melanocyte stimulating hormones , also known collectively as MSH , melanotropins or intermedins , are a family of peptide hormones and neuropeptides consisting of α-melanocyte stimulating hormone (α-MSH), β-melanocyte stimulating hormone ( β-MSH), and -melanocyte-stimulating hormone (γ-MSH) which are produced by cells in the pars intermedia of the anterior lobe of the pituitary gland. Synthetic …

Spindle Apparatus

Spindle Apparatus

Let’s know about Spindle Apparatus. In cell biology, the filamentous apparatus (or mitotic axle ) refers to the cytoskeletal structure of cells that forms during cell division to separate sister chromatids between daughter cells . This is known as the mitotic spindle during mitosis , a process that produces genetically identical daughter cells, or during …

What is the difference between metaphase 1 and metaphase 2

What is the difference between metaphase 1 and metaphase 2

Let us know what is the difference between metaphase 1 and metaphase 2Metaphase is one of the four stages of nuclear division in eukaryotic cells. The four stages of cell division in eukaryotes include prophase, metaphase, anaphase, and telophase. During metaphase, a cell’s chromosomes condense to their second most condensed state. The membranous nucleus breaks off, and the …

Sister Chromatid Exchange

Sister Chromatid Exchange

Sister chromatid exchange (SCE) is the exchange of genetic material between two identical sister chromatids . It was first discovered by using the Giemsa staining method on a chromatid sister-related complex before chromatid lysis in mitosis . Staining revealed that some segments assigned to sister chromatids were not dyed. Giemsa staining was able to stain …

Chromosome Segregation

Chromosome Segregation

Chromosome segregation is the process in eukaryotes by which two sister chromatids are formed as a result of DNA replication , or paired homologous chromosomes separate from each other and move to opposite poles of the nucleus . This separation process occurs during both mitosis and meiosis . Chromosome segregation also occurs in prokaryotes . …

Telophase

Telophase

Telophase is the final stage in both meiosis and mitosis in a eukaryotic cell . During telophase, the effects of prophase and prometaphase ( the nucleus and nuclear membrane disintegrate) are reversed. As the chromosomes reach the poles of the cell, a nuclear envelope reassembles around each set of chromatids , the nucleus reappears , …

Anaphase

Anaphase

Anaphase (from Greek , “up” and , “stage”), is the stage of the process of mitosis followed by metaphase , when repeated chromosomes divide and newly copied chromosomes (daughter chromatids ) are moved to opposite poles. Thesaurus. To help with chromosome segregation and re-formation of the nucleus, chromosomes reach their overall maximum condensation in late …
