What is convergent transcription?
What is convergent transcription?
Convergent transcription from two opposing promoters of partially overlapping genes on opposite strands of DNA gives rise to transcripts with potential sense–antisense interactions in the overlapping region.
What gene is transcribed?
Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes.
Is transcription unidirectional or bidirectional?
In an alternative model, transcription at its core is unidirectional, with the appearance of bidirectionality arising due to the adjacent placement of individual unidirectional core promoters in opposite orientations.
Where is a gene transcribed?
nucleus
Transcription takes place in the nucleus. It uses DNA as a template to make an RNA (mRNA) molecule. During transcription, a strand of mRNA is made that is complementary to a strand of DNA. Figure 1 shows how this occurs.
Is RNA transcribed 5 to 3?
RNA growth is always in the 5′ → 3′ direction: in other words, nucleotides are always added at a 3′ growing tip, as shown in Figure 10-6b. Because of the antiparallel nature of the nucleotide pairing, the fact that RNA is synthesized 5′ → 3′ means that the template strand must be oriented 3′ → 5′.
Are enhancers transcribed bidirectionally?
Enhancers are regulatory elements that activate promoter transcription over large distances and independently of orientation (Serfling et al. 1985). While both promoters and enhancers are known to bind transcription factors (TFs), only promoters were thought to initiate transcription by RNA polymerase II (Pol II).
What happens if RNA polymerase is not present?
Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. This process, which begins with the transcription of DNA into RNA, ultimately leads to changes in cell function. Changes in transcription are thus a fundamental means by which cell function is regulated across species.
Do enhancers get transcribed?
Which is the best definition of divergent transcription?
divergent transcription. Transcription started by two PROMOTERs acting in opposite directions so that transcription proceeds simultaneously in both directions from a point.
Where can I find the word divergent in the Dictionary?
Also found in: Thesaurus, Medical . 1. Drawing apart from a common point; diverging. 2. Departing from convention. 3. Differing from another: a divergent opinion. 4. Mathematics Failing to approach a limit; not convergent. American Heritage® Dictionary of the English Language, Fifth Edition.
What makes a divergent different from a non divergent?
A common characteristic among Divergent’s is the ability to control simulations. Unlike a non-Divergent person, they will have full awareness of the fact that they are in a simulation. OTHER FACTS: The majority of people born Divergent are from Abnegation.
Who is the author of the book divergent?
— Prachi Gupta, The Atlantic, “Indian Americans Are Stuck Between Hope and Despair,” 1 May 2021 Beginning with divergent research to understand the nature of the challenges, look broadly into areas directly related, as well as those analogous to the issue at hand.
