The hydrogen bonds between phosphates cause the DNA strand to twist. The nitrogenous bases point inward on the ladder and form pairs with bases on the other side, like rungs. Each base pair is formed from two c
How does mRNA differ from DNA?Nucleic Acids:Nucleic acids are a class of biomolecules that are essential to all life. They function to encode and store information. Composed of a pentose sugar, a nitrogenous base, and one to three phosphate groups, nucleotides are the monomer subunit of all ...
How is DNA information transferred to RNA? What is DNA replication? What is its importance? A particular triplet of bases in the template strand of DNA is 5'-AGT-3'. What would be the corresponding codon for the mRNA that is transcribed? Explain. ...
In this article, I review the results of studies on the origin of life distinct from the popular RNA world hypothesis. The alternate scenario postulates the origin of the first bimolecular genetic system (a polynucleotide gene and a polypeptide processiv
Uses RNA template, which is then reverse transcribed into cDNA (one DNA strand) Uses DNA template (two DNA strands) Uses RNA template, which is then reverse transcribed into cDNA (one DNA strand) Typically does not use fluorescence for product detection Typically uses fluorescence for product det...
Translation The process of making proteins from the mRNA template. Mutation Permanent change in the sequence of DNA. How can mutations affect an organism? Mutations can cause a cell to produce an incorrect protein during protein synthesis. As a result, the organism's trait, or phenotype, may ...
RNA triphosphatase catalyzes the first step in mRNA cap formation, hydrolysis of the terminal phosphate from the nascent mRNA transcript. The RNA triphosphatase from the protozoan parasite Trypanosoma cruzi, TcCet1, belongs to the family of triphosphate tunnel metalloenzymes (TTMs). TcCet1 is a ...
Structural and functional characterization of developmental intermediates from each branch revealed a rare mutation to be required in the broadly neutralizing branch, but not in the poorly neutralizing branch. Our results illustrate how a rare mutation can both restrict the later development and shape ...
Flower colour variation is one of the most crucial selection criteria in the breeding of a flowering pot plant, as is also the case for azalea (Rhododendron simsii hybrids). Flavonoid biosynthesis was studied intensively in several species. In azalea, fl
During DNA replication, how are the new nucleotides added to the template strand? Describe the various techniques used in DNA cloning. Explain step-by-step how DNA replication happens. Describe how the process of DNA transcription occurs.
