The dogmatic view of metabolite extraction with polar solvents is that larger biomolecules such as RNA, DNA, and protein are insoluble. Indeed, the insoluble fraction can be subsequently extracted and analyzed, enabling single-sample multi-‘omic workflows27,47,48. However, the presence of these ...

If the sequence of DNA is TTAGCATGGCTA, what will be the sequence of amino acids? a. What is the mRNA sequence for the following segment of DNA? --GACTATCCCATAGAG b. Based upon the mRNA sequence, what is the peptide sequence?
Creatine refers to a substance that gets produced in the muscle cells of our body. It involves a combination of amino acids L-arginine, L-methionine, and glycine. Most of this substance is produced naturally by our pancreas, kidney, and liver. Alternatively, they can also be sourced from pr...
Most of the ongoing projects aimed at the development of specific therapies and vaccines against COVID-19 use the SARS-CoV-2 spike (S) protein as the main target. The binding of the spike protein with the ACE2 receptor (ACE2) of the host cell constitutes
First, let's look at how DNA was discovered. DNA is one of a class of molecules called nucleic acids. Nucleic acids were originally discovered in 1868 by Friedrich Miescher, a Swiss biologist, who isolated DNA from pus cells on bandages. Although Miescher suspected that nucleic acids might ...
The four TPs coded by the NtOE23 gene were isolated from the genomic DNA of N. tabacum cv. Xanthi-nc and termed TP1, TP2, TP3, and TP4. Bioinformatic prediction using the ChloroP 1.1 program (http://www.cbs.dtu.dk/services/ChloroP/) identified 39 amino acids (TP1 and TP4) or 42...
These results are in agreement with current understanding of the types of amino acids that σ factors utilize for DNA interaction, and support a direct role for ComW in transcription activation at σX promoters. We expect that additional residues within these motifs aid in promoter recognition and...
DNA and RNA are macromolecules made up of monomeric subunits called [___] and bound together by [___] bonds. a. amino acids, peptide b. nucleotides, phosphodiester c. monosaccharides, glycosidic d. fatty acids, ester What macromolecules use gly...
