What You Must Know About RNA Transcription?

Among the most important discoveries in science was really the discovery of DNA. A deeper understanding of the DNA structure has now shown the answers to all of our concerns.The medical experts describe DNA codes for proteins in three stages: replication, transcription, and translation. After DNA's two strands have been replicated, transcription is used to copy the details into RNA.
After mRNA is produced, it goes through a series of post-transcriptional alterations to become mature mRNA, which would then be transferred from the nucleus to the cytoplasm, where ribosomes aid with protein synthesis.


Steps in Transcription

Initiation
To continue, transcription factors look for certain nucleotide sequences in the DNA known as gene promoters. The promoter portion of the gene, which includes the transcription initiation site, is then bound by RNA polymerase. RNA polymerase unwinds DNA into single strands that can be used as a basis for the synthesis of mRNA.

Elongation
To construct the corresponding mRNA strand, RNA polymerase attaches complementary nucleotides to both the 3' end of the template DNA strand. The mechanism continues as the RNA polymerase adds complementary bases to the DNA template, lengthening the mRNA chain. Dozens of rounds of transcription can result in the production of multiple copies of a gene.

Termination
The RNA polymerase continues through the DNA until it comes across a nucleotide sequence known as the terminator pattern, which stops transcription. The enzyme as well as the mRNA transcript disconnect from the template DNA that reconnects to form a double helix until transcription ceases. After that, the mRNA transcript or pre-mRNA is released for post-transcriptional adjustments that transform it into a mature mRNA that can be translated.

Oligonucleotide Therapeutics Is Proving To Be A Vital Drug For Fatal Diseases

We think there is not a single person in this world at this moment who is not aware about the COVID-19 pandemic. The virus has wreaked havoc throughout the world and put a lot of pressure on the healthcare facilities. This has brought scientists from all corners of the world together to find a solution to this problem. A new type of drug, known as oligonucleotide therapeutic, is believed to be the solution to this virus. There are companies online that provide custom DNA oligos. The Oligonucleotide Therapeutics Society has been doing its best to spread the awareness about this new drug and what potential it possesses to fight with the COVID-19. The distinct thing about oligonucleotide therapeutics is that the technology used to create it is rather different from the ones that are used to develop traditional drugs. In the case of oligonucleotide therapeutics, the technologies target disease at the level of RNA. These are drugs are the first drugs that have received the nod from the sc...

The Role of Nanotechnology in Cancer Therapy

 It’s not a new thing to mention that cancer is one of the leading causes of global deaths. Despite the research, treating patients with cancer is still an uphill battle. At present, chemotherapy and radiotherapy are two primary treatments suggested by healthcare professionals to destroy uncontrolled cell division. Although these treatment measures prove beneficial in countless cases, they also destroy healthy body cells and cancer cells. This eventually results in non-specific actions, including weakness, anemia, and loss of hair.  Since tumors’ pathological features are responsible for reducing the efficiency of standard cancer treatments, researchers are looking forward to RNA nanotechnology these days. The characteristics of nanoparticles, including smaller size and increased conjugate absorption, benefit the nanoscale vehicles, including magnetic nanoparticles, polymeric nanoparticles, liposomes, nanoshells, and dendrimers. The multifunctional characteristics of nanoparti...
