What are thin long strands of DNA that are coiled folded and twisted into short condensed strands?
Thin long strands of DNA that are coiled, folded, and twisted into condensed structures are called chromosomes. Chromosomes contain genes that carry the instructions for inherited traits and are organized within the nucleus of a cell. During cell division, chromosomes are visible as distinct entities under a microscope.
When a polypeptide is folded it is called what?
When a polypeptide is folded into its three-dimensional structure, it is referred to as a protein. Proteins are made up of one or more polypeptide chains that have folded into a specific conformation to perform their biological functions.
What structural characteristic of DNA allows it to be spooled out on a rod?
DNA's double helix structure allows it to be wrapped around histone proteins to form nucleosomes, which can be further coiled and folded to form chromatin. This coiling and folding of DNA allows for its compaction and spooling out on a rod during cell division or when storing genetic material.
Example of chromatin?
Chromatin is a complex of DNA and proteins found in the nucleus of cells. It undergoes structural changes to regulate gene expression. An example of chromatin is the condensed form, called heterochromatin, which is involved in gene silencing and maintenance of genomic integrity.
What contains a smooth outer and folded inner membrane in a cell?
The organelle that contains a smooth outer membrane and a folded inner membrane in a cell is the mitochondrion. Mitochondria are responsible for producing energy in the form of ATP through a process called cellular respiration.

What is the definition of flexibity?
Bendable twisted folded
Are polypeptides a carbohydrate?
No. Peptides are strings of amino acids. These proteins (peptides) are folded and coiled into polypeptides.
What is the definition for convolutions?
n. 1. A form or part that is folded or coiled. 2. One of the convex folds of the surface of the brain.
What do you call the 2 types of secondary protein structure which are evident in a polypeptide cha in?
The two types of secondary protein structure are alpha helix and beta sheet. In an alpha helix, the polypeptide chain is tightly coiled in a helical shape, while in a beta sheet, the polypeptide chain is folded into a sheet-like structure with hydrogen bonds between neighboring strands.
What does plico mean?
"Plico" is a Latin word that means "to fold" or "to bend." It can also be used to describe something being folded or twisted.
What is the definitions of convolutions and sulci?
convolutions: a form or part that is folded or coiled; one of the convex folds of the surface of the brain.Sulci: a shallow groove, such as that between gyri on the brain surface.
Why is it necessary to fold DNA?
The total length of DNA is so long that it cannot possibly fit inside a nucleus in its unfolded state. So DNA is folded and coiled around Histones for more compaction.
How does endomembrane system work together with the ribosomes?
The rough endoplasmic reticulum (RER) is where ribosomes will congregate to attach onto mRNA strands and transcribe the mRNA into protein strands. The smooth endoplasmic reticulum (SER) is where the protein strands made in the RER are folded, checked for problems and labeled for delivery to the appropriate location (cell membrane, other organelles, to be stored in a lysosome, etc.).
Which side of the plate does the napkin go?
Napkins can either be twisted neatly and placed in a fancy wine glass or water glass or, the napkin can be folded and laid to the right of the place with the knife on top.
How are protein strands folded?
Protein strands are folded into specific three-dimensional structures through a series of interactions among their amino acid residues. These interactions include hydrogen bonds, ionic bonds, hydrophobic interactions, and van der Waals forces, which help stabilize the folding process. The sequence of amino acids in the protein (its primary structure) dictates how the protein will fold, often allowing it to achieve its functional conformation. Chaperone proteins can also assist in the proper folding and prevent misfolding or aggregation.
How many folds are in the small intestine?
It's impossible to count. The entire structure of the small intestine is folded and coiled so it's impossible to identify individual folds. Also the small intestine can move around within the abdomen, so changes in shape are normal.
