Transcription takes place in the cell's nucleus where the DNA that is needed for the process is held. Transcription is the first of many steps that take place in the process of gene expression. Transcription transfers genetic information from the cells DNA to its RNA.Know More
DNA is a type of blueprint that tells the cells how to create proteins that are needed to fuel the cell and reproduce. The cell cannot understand these instructions without help though. The RNA comes in at this point and translates the information into a language the cells can understand. The process of transcription unzips the DNA by breaking the hydrogen bonds that hold it together. The mRNA is then able to move along the DNA strand, picking up the information it needs to begin to process the protein. This piece of RNA is referred to as a primary transcript.
The RNA is modified and synthesized by RNA polymerases, which are multi-subunit complexes found in all cells. The nucleotides of the RNA mesh with the complimentary ones on the DNA. Once all of the information is passed, the RNA strand will detach from those locations and the DNA strand will re-zip itself until the process needs to occur again. The processing of the RNA includes adding a cap and tail to the strand, then splicing it so that it is prepared to move into the translation phase.Learn more about Molecular Biology & DNA
Once the DNA is separated into two strands, an RNA primer is laid down to give the new strand a place to build from so that the new enzymes can mate up to the exposed bases of the DNA and continue to build until the strand is complete. The enzymes, specifically nucleotide triphosphate, must be complimentary for this to occur, which means that the A pairs with T and G with C. The base strand always dictates the replication order of the DNA strand.Full Answer >
Genetic splicing is the process in which an organism's DNA is cut and another gene is added. It is used so single-celled organisms can produce certain products, such as insulin, and produces genetically altered organisms.Full Answer >
DNA replication is a process in which DNA is duplicated so that it can be integrated into a new cell during cell division. The process produces two identical replicas of the DNA molecule from one original DNA molecule. It occurs in every living organism on Earth, allowing parental generations to pass on genes to their offspring.Full Answer >
The process of creating mRNA from the code in DNA is known as transcription. During transcription, RNA polymerase binds to DNA and synthesizes mRNA.Full Answer >
