The Central dogma explains how the DNA codes for the proteins which proceed in three stages, namely, replication, transcription and translation. Once DNA replicates its two strands, the information is copied into RNA by the process called transcription. Let’s learn more about the process of transcription. Table of Contents. Definition ...
Learn how transcription copies DNA into RNA using RNA polymerase and promoters. Explore the stages of transcription: initiation, elongation and termination, with examples from bacteria and humans.
- Having 2 strands is essential in the DNA replication process, where both strands act as a template in creating a copy of the DNA and repairing dama...
- *Great question*! Not during normal transcription, but in case RNA has to be modified, e.g. bacteriophage, there is T4 RNA ligase (Prokaryotic enzy...
- To add to the above answer, uracil is also less stable than thymine. RNA molecules are constantly being taken apart and put together in a cell, and...
- ATP is need at point where transcription facters get attached with promoter region of DNA , addition of nucleotides also need energy durring elonga...
- Termination in eukaryotes is much more complex and varies depending on the gene and organism. But generally, as mentioned in the article, a polyade...
- This is a good question, but far too complex to answer here. In fact, this is an area of active research and so a complete answer is still being wo...
- If you had, say, a paper clip, and you stretched it out so the wire was straight, and then hold it by one end and press it into a wall, what would...
- Promoters and terminators do not get copied into the new transcript. The promoter is there to tell the RNA to "get ready" and signal the start of t...
- The article says that in Rho-independent termination, RNA polymerase stumbles upon rich C region which causes mRNA to fold on itself (to connect C...
Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence.
Jun 14, 2024 · transcription, the synthesis of RNA from DNA. Genetic information flows from DNA into protein, the substance that gives an organism its form. This flow of information occurs through the sequential processes of transcription (DNA to RNA) and translation (RNA to protein).

The segments of DNA transcribed into RNA molecules that can encode proteins produce messenger RNA (mRNA). Other segments of DNA are transcribed into RNA molecules called non-coding RNAs (ncRNAs). Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.
The process of making a ribonucleic acid (RNA) copy of a DNA (deoxyribonucleic acid) molecule, called transcription, is necessary for all forms of life.
4 days ago · Transcription, as related to genomics, is the process of making an RNA copy of a gene’s DNA sequence. This copy, called messenger RNA (mRNA), carries the gene’s protein information encoded in DNA.
