b. How are the two DNA strands in a double-stranded (duplex) DNA molecule arrange Explain the importance of hydrogen bonds in the structure of DNA, and to the process of DNA replication. How can the structure and function of nucleotides (DNA and RNA) allow the cell to assemble s...
How many nucleotides are in a human chromosome? What enzyme fixes mistakes in DNA replication? What enzyme unzips the DNA double helix? What is accomplished by DNA replication? How many nucleotides make up a codon? How many hydrogen bonds are in DNA?
METAL-metal bondsMETALLOPROTEINSDENSITY functional theoryLIGANDS (Biochemistry)STRENGTH of materialsMETAL complexesOXIDATIONQUANTUM mechanicsWe have used density functional theory calculations to investigate how the hydrogen-bond strength is modified when a ligand is bound to a metal using over 60...
The phosphate of one nucleotide iscovalently 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 phosphates cause the DNA strand to twist. The nitrogenous bases point inward on the ladder and form pair...

We have theoretically analyzed mimics of Watson-Crick AT and GC base pairs in which N-H···O hydrogen bonds are replaced by N-H···S, using the generalized gradient approximation (GGA) of density functional theory at BP86/TZ2P level. The general effect of the above substitutions is an...
First, water molecules (two atoms of hydrogen and one atom of oxygen joined together) naturally stick to one another, so they clump together in big droplets on the window. The forces that make them do this are called cohesive forces (and the process involved is called cohesion). Second, ...
The heat disrupts the hydrogen bonds that hold secondary and tertiary structures while a reducing agent, such as β-mercaptoethanol, cleaves disulfide bridges. Proteins are linearized and complex with the SDS so that all have a similar mass-to-charge ratio. This e...
