How is double helix used in a sentence?
Double Helix the structure of double coiled DNA
What is the shape of a DNA molecule formed when two twisted DNA strands are coiled into a springlike structure?
When two complimentary threads of DNA coil round each other they form a double helix pattern. They can coil up further to form chromosomes.
What levels of protein folding would include shapes identified as helix and pleated sheet?
This is the secondary folding phase where hydrogen bonds between the side chains give you the alpha helix and the beta pleated sheet.
What is one of the structure basis found in DNA?
The double helix
What did Watson Crick discover about the structure of DNA?
It was a double helix.
A peptide can form a structure such as a helix or a?
sheet
A peptide can form a structure such as a or a sheet?
helix
The alpha helix and pleated sheet are examples of?
secondary structure of a protein
Structure of keratin?
Alpha keratin has alpha helix structure and beta keratin has beta pleated sheet structure.
What type of protein shape is characterized by the alpha helix or a flat-pleated sheet?
secondary structure
The alpha helix and beta pleated sheet represent which level of protein structure?
The alpha helix and beta sheets are found at the Secondary level of protein folding. It's when the protein is taking its shape. Secondary structure
Name two types of secondary protein structure Explain the role of hydrogen bonds in maintaining secondary structure?
alpha Helix and Beta pleated sheet
What are the various characteristics of Watson -crick double helix model for DNA?
here are some characteristics: 1. The Double Helix Structure 2. The Ladder Shape 3. The Twisted Form
What are helix proteins?
There are no known proteins such as helix proteins. Alpha helix is a secondary structure element found in proteins that formed by amino acids which can form helix. Other secondary structures are beta sheets and random coils.
Do the coils and folds of a protein's amino acid chain make up the protein's primary structure?
The coils of an alpha helix or the folds of a beta-pleated sheet are a characteristic of the secondary structure.
What type of interaction stabilizes the secondary structure of a protein causing it to form an alpha-helix?
In an α-helix, the polypeptide backbone forms a repeating helical structure that is stabilized by hydrogen bonds between a carbonyl oxygen and an amine hydrogen. These hydrogen bonds occur at regular intervals of one hydrogen bond every fourth amino acid and cause the polypeptide backbone to form a helix.
What type of structure is the DNA?
Double Helix
