Hi, The DNA Helix is simply another name for DNA, and such name is used because DNA is in a double helix shape. The DNA is what determines who you are and therefore is found in every cell in our body. It is the genetic information of a human being and it contains genes, which are what determines our traits. For example, there are genes that control eye color, hair color, size of body...etc.

∙ 10y agoThe DNA helix is formed by the hydrogen bonding of the oxygen in the carboxyl group on one amino acid and the hydrogen in the amino group of the second amino acid.
William Astbury dicovered two different protein structures called alpha form and beta form. The alpha form was a coiled protein that was not stretched out and the beta form was produced when the coil was stretched.
Even though his ideas were not correct naming system of the alpha and beta were kept as the names of the two most common secondary structures for proteins as the alpha helix and the beta pleated sheet.

∙ 8y agoAn alpha helix is a secondary structure found in proteins, in which the amino acids are arranged in a coil, or helix, with almost no free space on the inside, and all side chains pointed towards the outside.

∙ 7y agoThe alpha helix is the classic element of protein structure. First described by Linus Pauling in 1951 at CalTech, alpha helices in proteins are found when a stretch of consecutive amino acid residues all have the phi, psi angle pair (that is formed by the rotation of the planar peptide bond) approximately -60o and -50o (specifically, corresponding to the allowed region of the bottom left quadrant of the Ramachandran plot).
The alpha helix has 3.6 amino acid residues per turn with hydrogen bonds between C'=O of residue n and NH of residue n+4, thus, all NH and C'O groups are joined with hydrogen bonds except the first NH groups and the last C'O groups at the ends of the alpha helix. Alpha helices vary considerably in lenght in globular proteins ranging from four to five amino acid residues to over 40. The average lenght is around 10 amino acid residues, corresponding to three turns

What level of protein structure is represented by the coiling of the protein chain backbone into an alpha helix?
The coiling of the protein chain background into an alpha helix is the secondary structure. This is caused by the H-bonded arrangement of the backbone of th protein.
What are the two most common secondary structures in a protein?
The two types of tertiary protein structures: globular and fibrous proteins. Globular proteins act as enzymes that catalyze chemical reactions in organisms. Fibrous proteins like collagen play structural role.
Name two types of secondary protein structure Explain the role of hydrogen bonds in maintaining secondary structure?
alpha Helix and Beta pleated sheet
Secondary protein structure?
The secondary structure of protein:the ordered 3-d arrangements in localized area of a polypeptide chaininteractions of the peptide backbone (s-trans and planar)example of secondary structure : alpha-helix and beta-pleated sheet
What is a single helix molecule?
A DNA molecule has the shape of a double-stranded helix.
What type of helix forms RNA?
Alpha helix
What did Herman branson invent?
The alpha helix
How does collagen helix differs from alpha helix?
A collagen helix is less compact (because it goes into triple helices), and it is a left-handed helix. An alpha helix is more compact and hence requires more rotation of bonds to form (hence proline is not very common...has an imidazole ring). It is a right-handed helix, and goes into double helices instead.
Why is Branson famous?
He is famous because of his research of Alpha Helix protein structure. It is spiral chain of amino acids stabilized by hydrogen bonds.http://www.answers.com/topic/alpha-helix
How do you find out the length of alpha helix and beta helix?
This is quite simple. Using stoichiometry to keep track of units, simply take the number of amino acids in the particular alpha helix and multiply by 15 angstroms. This is the length the alpha helix is advanced along the length axis by each additional A.A. For a beta helix it become more difficult however and you must know how many sheets you are taking into account.
Hemoglobin is an example of a protein with what type of structure?
Alpha Helix.

The coiling of the protein chain backbone into an alpha helix is referred to as?
The coiling of the protein chain backbone into an alpha helix is referred to as the secondary structure. It is composed of several polypeptide chains.
What structure refers to the twisting spiral shape formed by the sequence and properties of amino acids?
The phrasing is a little odd, but I suspect the term you're looking for is "alpha helix". Other "twisting spiral shapes" are possible, for example the 3.10 helix and the pi helix, but the alpha helix is the most common and most familiar.
Structure of keratin?
Alpha keratin has alpha helix structure and beta keratin has beta pleated sheet structure.
What protiens are found in plasma?
any Alpha helix formations of protien.
The alpha helix and pleated sheet are examples of?
secondary structure of a protein
