Hace 2 días · In molecular biology, a transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence.
Hace 1 día · Transcription. miRNA genes are usually transcribed by RNA polymerase II (Pol II). The polymerase often binds to a promoter found near the DNA sequence, encoding what will become the hairpin loop of the pre-miRNA.
Hace 4 días · Definition. 00:00. … Gene expression is the process by which the information encoded in a gene is turned into a function. This mostly occurs via the transcription of RNA molecules that code for proteins or non-coding RNA molecules that serve other functions.
Hace 1 día · Messenger RNA (abbreviated mRNA) is a type of single-stranded RNA involved in protein synthesis. mRNA is made from a DNA template during the process of transcription.
Hace 5 días · Transfer RNA (abbreviated tRNA) is a small RNA molecule that plays a key role in protein synthesis. Transfer RNA serves as a link (or adaptor) between the messenger RNA (mRNA) molecule and the growing chain of amino acids that make up a protein.
Hace 5 días · Analysis of genes involved in methionine metabolism revealed a second global transcription antitermination system, dedicated to genes in this pathway. Like the T box system, the S box system is widely used in Gram-positive organisms.
Hace 4 días · This transcription system is a variation of Nanking Syllabary, a system developed by Herbert Giles in 1892. It was adopted by the Chinese Imperial Post, part of the Chinese Maritime Customs Service led by Irishman Robert Hart. It is based on pronunciation in the Southern Mandarin, or Jianghuai, dialect.
