although both DNA and RNA nucleotides have a pentose sugar, their sugar molecules differ slightly. For example, in DNA, the pentose sugar is called deoxyribose, whereas in RNA, the pentose sugar is called ribose. Figure 2 shows the structures of the two sugar molecules...
RNA, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides and the nitrogenous bases adenine, guanine, cytosine, and uraci
A nucleotide is the building block (monomer) of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) but can also be found existing alone as adenosine triphosphate (ATP), an energy carrier molecule. A nucleotide is composed of a sugar, a phosphate group, and a nitrogenous base. To ...
Is transfer RNA a protein? What is a segmented RNA virus? How many different kinds of proteins does one cell contain? Does transfer RNA convert DNA to mRNA? What are the structures of RNA and DNA and how might one be used to create the other?
In particular, the ion distributions may not balance all the local electronegativity of the molecule. These ion distributions do not only greatly affect local structures but also lead to different local dynamics of RNA. We studied the effects of different ion solutions on the structure and dynamics...

Types of Organelles Organelles are small membrane-bound structures found ineukaryotic cells. They handle specialized functions that are either missing in or that are carried out throughout the cell in simpler single-cell organisms. Because they specialize in specific organelle functions inside their ...
Membrane proteins are proteins that are embedded in the cell membrane of cells. They have a diverse range of different functions, and depending on the cell type, can constitute over 50% of the total mass of the cell membrane. Answer and Explanation: ...
Penicillins and cephalosporins have similar structures so they act in similar ways. These compounds bind to and block the activity of enzymes that make peptidoglycan, the major component of most bacterial cell walls. Peptidoglycan is a polymer made up of long parallel strands of sugar molecules (...
Prostate tumor heterogeneity is a major factor in disease management. Heterogeneity could be due to multiple cancer cell types with distinct gene expression. Of clinical importance is the so-called cancer stem cell type. Cell type-specific transcriptomes
