Life is a 2017 American science fiction horror film [5] [6] [7] directed by Daniel Espinosa, written by Rhett Reese and Paul Wernick and starring an ensemble cast consisting of Jake Gyllenhaal, Rebecca Ferguson, Ryan Reynolds, Hiroyuki Sanada, Ariyon Bakare, and Olga Dihovichnaya.
A highly evolved [vague] RNA polymerase ribozyme was able to function as a reverse transcriptase, that is, it can synthesize a DNA copy using an RNA template. [36] Such an activity is considered [by whom?] to have been crucial for the transition from RNA to DNA genomes during the early history of life on earth. Reverse transcription capability ...
Life is a 2015 biographical drama film directed by Anton Corbijn and written by Luke Davies. It is based on the friendship of Life photographer Dennis Stock and American actor James Dean , starring Robert Pattinson as Stock and Dane DeHaan as Dean.
Reverse transcription loop-mediated isothermal amplification (RT-LAMP) is a one step nucleic acid amplification method to multiply specific sequences of RNA. It is used to diagnose infectious disease caused by RNA viruses. [1] It combines LAMP [2] DNA-detection with reverse transcription, making cDNA from RNA before running the reaction. [3]
This RNA is complementary to the template 3′ → 5′ DNA strand, [1] with the exception that thymines (T) are replaced with uracils (U) in the RNA and possible errors. In bacteria, transcription is carried out by a single type of RNA polymerase, which needs to bind a DNA sequence called a Pribnow box with the help of the sigma factor protein ...
Many viruses replicate this way. The enzymes that copy RNA to new RNA, called RNA-dependent RNA polymerases, are also found in many eukaryotes where they are involved in RNA silencing. [11] RNA editing, in which an RNA sequence is altered by a complex of proteins and a "guide RNA", could also be seen as an RNA-to-RNA transfer.
RNA-dependent DNA polymerases are a specialized class of polymerases that copy the sequence of an RNA strand into DNA. They include reverse transcriptase , which is a viral enzyme involved in the infection of cells by retroviruses , and telomerase , which is required for the replication of telomeres.
Nucleic acid amplification is a technique used to produce several copies of a specific segment of RNA/DNA. [3] Amplified RNA and DNA can be used for a variety of applications, such as genotyping, sequencing, and detection of bacteria or viruses. [4] There are two different types of amplification, non-isothermal and isothermal. [5]
