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.
A chromogenic print, also known as a C-print or C-type print, [1] a silver halide print, [2] or a dye coupler print, [3] is a photographic print made from a color negative, transparency or digital image, and developed using a chromogenic process. [4]
A sigma factor is a protein needed only for initiation of RNA synthesis in bacteria. [12] Sigma factors provide promoter recognition specificity to the RNA polymerase (RNAP) and contribute to DNA strand separation, then dissociating from the RNA polymerase core enzyme following transcription initiation. [ 13 ]
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.
Different models of 3D printing tissue and organs. Three dimensional (3D) bioprinting is the use of 3D printing–like techniques to combine cells, growth factors, bio-inks, and biomaterials to fabricate functional structures that were traditionally used for tissue engineering applications but in recent times have seen increased interest in other applications such as biosensing, and ...
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 ...
If time is the responsible factor, it may be possible to delay cell division in clones, giving time for proper reprogramming to occur. [citation needed] In vitro fertilisation, including ICSI, is associated with an increased risk of imprinting disorders, with an odds ratio of 3.7 (95% confidence interval 1.4 to 9.7). [69]
Transcription preinitiation complex, represented by the central cluster of proteins, causes RNA polymerase to bind to target DNA site. The PIC is able to bind both the promoter sequence near the gene to be transcribed and an enhancer sequence in a different part of the genome, allowing enhancer sequences to regulate a gene distant from it.
