A DNA molecule is often called a what because it twists like the threads of a screw?
DNA is a molecule responsible for the genetic instructions, development and functioning of living organisms. The DNA molecules that contain millions of nucleotides and is very large, called DNA polymer.
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.
What are the differences between a right-handed alpha helix and a left-handed alpha helix in protein structures?
The main difference between a right-handed alpha helix and a left-handed alpha helix in protein structures is the direction in which the helix twists. In a right-handed alpha helix, the helix twists in a clockwise direction, while in a left-handed alpha helix, the helix twists in a counterclockwise direction. This difference in twisting direction affects the overall shape and stability of the protein structure.
When was Helix goderdziana created?
Helix goderdziana was described as a new land snail species in 2018.
Single helix is more stable as compared to the double helix?
The double helix of DNA is more stable than a single helix due to the hydrogen bonding between complementary base pairs and the structural support provided by the sugar-phosphate backbone. The double helix structure allows for efficient storage and replication of genetic information.
How are the inclined plane and wedge and screw related?
By rotation (or helix).
What looks like a screw?
A helix, a vine tendril, a circular set of stairs...
What are the simple machines with in the Archimedes screw?
An Archimedes' screw is a screw which, when twisted inside a cylinder, raises water from a lower level to a higher level, allowing irrigation of fields.
What is a inclined plane wrapped around a cylinder?
That describes a screw or a bolt, or a similar device.
An inclined plane wrapped around a cylindrical post is a?
An inclined plane wrapped around a cylindrical post is called a screw.
What is a Helix shape?
A helix is a three-dimensional curved shape that resembles a corkscrew or spiral. It is formed by a curved line wrapping around a central axis. Helix shapes are often found in nature, such as in DNA molecules or certain types of shells.
An inclined plane wrapped around a cylinder is called?
A screw or a bolt is an inclined plane wrapped around a cylinder.
What kind of spirals of are all spaced an equal distance apart for a given a radius?
A helix. Examples are the threads on a screw or a spiral staircase
What shape was Archimedes known for?
Archimedes is remembered (among many other things) for the Screw Pump which he invented to pump water out of a ship. It is an inclined,circular pipe containing a helix with its lower end dipped in the water. Turning the helix/screw around its shaft raises the waterin the pipe, thus liftingit and 'pumping' it to a higher level.
What is screw thread?
This is a tool that is used to measure the pitch diameter of a screw. This tool looks like a standard micrometer except that the anvils are specially configured to reach into the screw thread groove and touch the pitch diameter of the screw thread. The screw thread micrometer does not measure any other aspect of the screw thread. It does not measure the: pitch; threads-per-inch; major diameter; minor diameter; flank angles; lead; helix angle.
what is the shape of a DNA?
double helix
How do you activate quad helix appliance?
