Which one of the monomers below would most readily polymerize, using an anionic mechanism? What are three possible components of a DNA nucleotide? What type of organic compound is DNA? What are the nucleic acids? What type of biological molecule is DNA helicase? What does albumin have that ri...
Diatomic molecules are when only two atoms combine. An example of adiatomic moleculeis carbon monoxide (CO) made of a single atom of carbon and one of oxygen. If the two atoms are the same element, it is called ahomonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).Poly...
What type of macromolecule is an enzyme? What type of organic molecule is DNA? What is type B-DNA? What are the components and structure of a DNA nucleotide? What is the structure of a nucleotide? What kind of macromolecule is made from amino acids?
DNA is the molecule that contains all of the information required to build and maintain the cell; RNA has several roles associated with expression of the information stored in DNA. Of course, nucleic acids alone aren't responsible for the preservation and expression of genetic material: Cells ...
What is DNA made of? DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (...

cycle to generate energy. Each cycle of beta-oxidation removes two carbon atoms from the fatty acid chain and produces one molecule each of NADH and FADH2, which can be used for oxidative phosphorylation to produce ATP. Since fatty acid oxidation can occur multiple times, the energy yield is ...
If there is one thing that both unites and separates all living organisms in the world, it is DNA. Plants, animals andbacteriaall contain the essential biological molecule known asDNAor deoxyribonucleic acid. DNA contains all the information required to build and maintain living organisms. You can...
this, a DNA molecule is cut into smaller pieces and then used as a template for a particular strand of RNA that has been copied from the DNA’s matching complementary strand. This RNA is then able to match up with each piece of DNA and can be read off slowly, one letter at a time...
