Nucleotides are unique and in DNA, they bond in pairs: Cytosine binds with guanine and adenine binds with thymine. In ribonucleic acid, which is commonly seen in its abbreviated form, RNA, there exists an additional nucleotide called uracil. In RNA, uracil replaces the nucleotide, thymine. ...
The structure affects how well the bases bond together and the number of hydrogen bonds that are formed. When cytosine bonds with guanine, three hydrogen bonds form between the two bases. When adenine bonds with thymine or uracil, only two hydrogen bonds are formed. Only these base pairs are...
What type of bonding between the A-T and G-C base pairs helps hold the two DNA strands in duplex together? Which type of bonds attach the nucleotides with each other ? What type of bonds spontaneously form between two complementary strands of DNA? A) Hydrogen bonds B) Covalent bonds C...
DNA is a polymer, meaning it is made up of many thousands of individual pieces strung up together, like a pearl necklace. The individual units are called nucleotides. Each nucleotide has three parts: a sugar, called deoxyribose; a phosphate group; and one of four nitrogenous bases. The possi...
Double-stranded DNA is a molecule composed of two strands of DNA that twist around one another to form a double helix. The two strands are held together by hydrogen bonds that form between complementary base pairs of nucleotides (A pairs with T, and C with G) on each strand. If the ...
In the double helix, each of the base pair consists of two complementary nucleotides where a purine pairs with a pyrimidine. Here, the complementary relationship between the base pairs has been attributed to their shape which allows two particular bases to bind together through hydrogen bonds. ...
Nucleotides are the monomers that make up DNA and RNA. 7 Dimer A chemical compound or molecule consisting of two identical simpler molecules. Monomer A monomer ( MON-ə-mər; mono-, "one" + -mer, "part") is a molecule that can react together with other monomer molecules to form a...

A simple definition ofproteinsis that they are molecules made of amino acid residues joined withpeptide bonds. Amino acidsare molecules made up of an amino group, an acidic carboxyl group, and an organicRgroup. They are coded for with various combinations of three DNA nucleotides. ...
nucleotides on DNA. Only one of the two strands of DNA is used in this process. The sequence of nucleotides in mRNA being produced is always complementary to the DNA strand used for synthesis. Besides, there is uracil in RNA instead of thymine of DNA. This process of RNA synthesis is ...
