How do prokaryotes distinguish the newly synthesized strand from the old template strand? Why don't eukaryotes use the same mechanism? The function of RNA to DNA include the replication, transcription, and translation. Explain these three processes...
Once a strand of RNA is made in the nucleus, explain what needs to happen to the RNA before it becomes MRNA and leave the nucleus. Why do RNA viruses mutate faster than DNA? How does RNA know how to read the DNA? Explain how DNA codes for traits. Be sure to discuss RNA and protei...
The phosphate of one nucleotide iscovalently bound(a bond in which one or more pairs of electrons are shared by two atoms) to the sugar of the next nucleotide. The hydrogen bonds between phosphates cause the DNA strand to twist. The nitrogenous bases point inward on the ladder and form pair...
There is a growing concern that the current vaccines may not protect people from the newly emerging variants of SARS-CoV-2. However, the faster development of mRNA vaccines than the other vaccine types may be a solution to prevent against the current and future variants as well as other ...
To make mRNA, RNA polymerase: Binds to the DNA strand at a specific sequence of the gene called a promoter Unwinds and unlinks the two strands of DNA Uses one of the DNA strands as a guide or template Matches new nucleotides with their complements on the DNA strand (G with C, A with...
a special enzyme and then rejoined into a shorter mRNA strand that will code for a functional protein. Therefore, the original coding DNA strand is not directly translated into protein, but must go through an alteration step as mRNA to remove nonsense sequences that do not code for a gene....
Transcription is the process in which mRNA is synthesized from a DNA template. In principle, given what you now know, you can easily envision how this happens. DNA is double-stranded, so each strand can serve as a template for single-stranded RNA; these two new RNA strands, owing to the...

Initiation- In first step the RNA polymerase will bind to the promoter region of the gene. It will then... See full answer below. start untangling the double stranded structure of DNA and expose the single strand of DNA which will be required as a template for building RNA. ...
DNA is so important that the United States government has spent enormous amounts of money to sequence DNA in the human genome in hopes of understanding and finding cures for many genetic diseases. Finally, from the DNA of one cell, we can clone an animal, a plant or perhaps even a human...
