What does the Lysosome do in a animal cell?
Lysosome Definition Lysosome is a membrane-enclosed cellular organelle that possesses distinct enzymes involved in the digestion of unwanted or damaged cellular polymers including proteins, DNA, RNA, carbohydrates, and lipids. Lysosomes … Read more
What does Mitochondria do in a cell?
Mitochondria Definition Mitochondria are double membrane-bound cytoplasmic organelles found in all eukaryotic cells. They respire to generate an energy-rich molecule, adenosine triphosphate (ATP), through the breakdown of carbohydrates and fatty … Read more
Genotype Definition, Characteristics, Explanation and Examples
Genotype Definition A genotype is an inherent genetic property of living forms, that contains genes inherited from both the mother and father of the organism. The genotype determines the structural … Read more
What is mTOR? | Signaling Pathway | Inhibitors
mTOR Definition mTOR is a highly conserved serine/threonine-protein kinase enzyme, initially found in mammals. The activity of mTOR protein kinase can be inhibited by a drug, rapamycin, to reduce the … Read more
DNA replication of prokaryotes
Prokaryotic DNA replication is an anabolic process by which prokaryotes duplicate their genomic DNA to transfer it to their daughter cells. DNA replication in prokaryotes especially in E. coli (model … Read more
Helicase vs Topoisomerase (DNA gyrase)
Recently, several studies have found the direct interactions between helicase and topoisomerase. However, several variations were found in their mode of functions. The major differences between helicase and topoisomerase Helicase … Read more
DNA replication in eukaryotes
Key points of DNA replication in eukaryotes The genomic DNA of eukaryotic is 10 to 1000 times larger than the bacterial genomic DNA. The genomic DNA of eukaryotes is organized … Read more
DNA replication models
DNA replication is a process by which the genetic information stored in chromosomal DNA is transmitted from one generation to successive generations. Proper development of -organisms of succeeding generation can … Read more
DNA dependent DNA polymerase
Definition: The genetic material such as DNA is synthesized by an enzyme called DNA dependent DNA polymerase that uses parental DNA strands as templates and synthesizes the new DNA strands. … Read more
