Answer :
When U binds extremely weakly with A, the four u nucleotide in the mrna transcript play a crucial role in the termination of transcription because this causes the stopped RNA polymerase to separate from the DNA.
What do you mean when you say "nucleotides"?
A phosphate as well as a nucleoside make up the chemical molecules known as nucleotides. They function are monomeric units of a deoxyribonucleic acid & ribonucleic acid polymers, which are both crucial macromolecules for all kinds of life on Earth. Nucleotides can be consumed in addition to being synthesized by liver from common nutrients. The nucleobase, a five-carbon sugars (ribose or deoxyribose), or a phosphate group made up of one to three phosphates are the three component molecules that make up a nucleotide. Guanine, adenine, cytosine, and thymine are the four nucleobases found in DNA; uracil is often used in place of thymine in RNA.
What are the 5 major nucleotides and why nucleotides are so important ?
The initial letter of each of the five bases found in nucleotides—adenine, guanine, cytosine, thymine, and uracil—is frequently used to denote that base in a nucleotide. RNA contains the letters А, G, C, & T while DNA has the letters A, G, C, & U. Because nucleotides seem to be the basic building block of nucleic acids, which are the molecules that regulate all genetic features, they are crucial to living organisms.
