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.
Merozygote is a state when a cell, usually bacterial, is temporarily partial diploid as result of DNA transfer processes like conjugation. [1]One example of how merozygotes can be formed is the transfer of genetic material of an Hfr cell to an F − cell (in other words a bacterium without the F-factor) through conjugation.
Transcription factors and associated proteins that bind promoters, enhancers, or silencers to drive or repress transcription are fundamental to understanding the unique regulation of individual genes within the genome. Techniques like DNA footprinting help elucidate which proteins bind to these associated regions of DNA and unravel the ...
In number theory, the prime omega functions and () count the number of prime factors of a natural number . Thereby ω ( n ) {\displaystyle \omega (n)} (little omega) counts each distinct prime factor, whereas the related function Ω ( n ) {\displaystyle \Omega (n)} (big omega) counts the total number of prime factors of n , {\displaystyle n ...
In molecular biology and genetics, upstream and downstream both refer to relative positions of genetic code in DNA or RNA.Each strand of DNA or RNA has a 5' end and a 3' end, so named for the carbon position on the deoxyribose (or ribose) ring.
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]
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 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.
