lcm(m, n) (least common multiple of m and n) is the product of all prime factors of m or n (with the largest multiplicity for m or n). gcd(m, n) × lcm(m, n) = m × n. Finding the prime factors is often harder than computing gcd and lcm using other algorithms which do not require known prime factorization.
Because of the RNA polymerase association with sigma factor, the complete RNA polymerase therefore has 6 subunits: the sigma subunit-in addition to the two alpha (α), one beta (β), one beta prime (β'), and one omega (ω) subunits that make up the core enzyme(~450 kDa). In addition, many bacteria can have multiple alternative σ factors.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
The F factor was the first plasmid to be discovered. Unlike other plasmids, F factor is constitutive for transfer proteins due to a mutation in the gene finO . [ 4 ] The F plasmid belongs to F-like plasmids , a class of conjugative plasmids that control sexual functions of bacteria with a fertility inhibition (Fin) system.
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...
The MADS box is a conserved sequence motif.The genes which contain this motif are called the MADS-box gene family. [1] The MADS box encodes the DNA-binding MADS domain. The MADS domain binds to DNA sequences of high similarity to the motif CC[A/T] 6 GG termed the CArG-box. [2]
However, very little has been studied about Archean release factors. [20] In prokaryotes, the release factors are characterized in 2 classes. Class 1 release factors recognize stop codon, and class 2 release factors stimulate hydrolysis by GTPase activity. However, prokaryotes don't have a single protein to recognize all the stop codons.
PRIME (probe incorporation mediated by enzymes) is a molecular biology research tool developed by Alice Y. Ting and the Ting Lab at MIT for site-specific labeling of proteins in living cells with chemical probes. [1] [2] Probes often have useful biophysical properties, such as fluorescence, and allow imaging of proteins. [1]
