A nucleotide is the basic of polynucleotide chain of DNA and each nucleotide is composed of three components - i) a nitrogenous base, ii) a pentose sugar and iii) a phosphate group. Nitrogen base is attached to the pentose sugar by an N-glycosidic linkage forming a nucleoside. A phosphodi...
DNA has a structure called a double helix. Nucleotides are attached together to form two long strands that spiral to create this structure. If you think of the double-helix as a ladder, the phosphate and sugar molecules would be the sides, while the base pairs would be the rungs. The ba...
A monomer is a molecule that serves as the building block of larger molecules called polymers. One example of monomers is nucleotides. Nucleotides are made up of a sugar-phosphate complex and a nitrogenous base. There are two main groups of nit...

The 9-1-1 DNA checkpoint clamp is loaded onto 5′-recessed DNA to activate the DNA damage checkpoint that arrests the cell cycle. The 9-1-1 clamp is a heterotrimeric ring that is loaded in Saccharomyces cerevisiae by Rad24-RFC (hRAD17-RFC), an alternate
Crystal structures of P. shermanii MCM were determined (12, 13) that revealed that both α and β subunits consist of two principal domains: an eight-stranded α/β triose phosphate isomerase barrel (α/β)8 and a flavodoxin-like AdoCbl-binding fold. The cofactor is sandwiched between the ...
Collectively, these data demonstrated Z-DNA as a component of the EPS of biofilms formed as part of the bacterial disease course. Z-DNA was the primary structural form of eDNA within mature biofilms We expanded our hypothesis to consider that in addition to DNase-resistance, Z-DNA and not B...
What is a nucleotide? A. The combination of nitrogenous base, sugar, and phosphate group B. Phosphate units C. Deoxyribose D. The combination of deoxyribose and a phosphate group Describe the structure of adenine. a. base found in only DNA b. ba...
Recent studies have revealed the importance of long noncoding RNAs (lncRNAs) as tissue-specific regulators of gene expression. There is ample evidence that distinct types of vasculature undergo tight transcriptional control to preserve their structure, i
