How does protein synthesis enable DNA to control the cell? What is the role of nucleotides in DNA? How do proteins assist in DNA replication? What makes one DNA molecule different from another? How does the structure of DNA result in accurate replication?
How does Z-DNA form? As DNA is replicated, which DNA base pair will bond to cytosine? adenine thymine cytosine guanine? What kind of chemical bond is found between paired bases of the DNA double helix? How are nucleotides linked? Why do adenine and thymine have a double bond? Is Z-DNA...
The sides of the ladder comprise the sugar-phosphate portions of adjacent nucleotides bonded together. The phosphate of one nucleotide is covalently bound (a bond in which one or more pairs of electrons are shared by two atoms) to the sugar of the next nucleotide. The hydrogen bonds between ...
Structure of DNA: DNA is composed of two antiparallel strands of nucleic acids that are held together by hydrogen bonds between the nitrogenous bases of opposing strands. The backbone of each strand of DNA is composed of alternating phosphate and deoxyribose molecules. ...
Let's start at the beginning with nucleic acids. Monomers called nucleotides join together to make polymers called nucleic acids. Each nucleotide consists of a 5-carbon sugar, a phosphate group (phosphorus with oxygens attached), and a nitrogenous base. These nitrogenous bases form the 'alphabet...
The proportion of nucleotides in the human genome for which the personal history during the last 500 million years matches the canonical vertebrate tree is minute. Nobody complains when, in vertebrates, people discard paralogues (which they circularly iden- tify thanks to prior speculations about ...
Streptococcus suis is a zoonotic agent that causes sepsis and meningitis in pigs and humans. S. suis infections are responsible for large economic losses in pig production. The lack of effective vaccines to prevent the disease has promoted the extensive
Subpopulations of soluble, misfolded proteins can bypass chaperones within cells. The extent of this phenomenon and how it happens at the molecular level are unknown. Through a meta-analysis of the experimental literature we find that in all quantitative
A. RNA nucleotides have a unique phosphodiester bond linkage. B. RNA nucleotides have uracil nitrogenous bases. C. RNA nucleotides have an -OH on the 2' carbon of the ribose. D. RNA How is DNA synthesized artificially? How does this differ from DNA synthesis in a cell? Examine three ...
How do bases pair in complementary strands of DNA? Explain. How are proteins and nucleic acids related? How does DNA polymerase add nucleotides? How is protein synthesis initiated in a cell? Why is DNA ligase important for a cell? How does an operon organize DNA and regulate gene expression...
