Auricle is the external feature of ear that contains the helix and lobule.
The twisted ladder shape of a DNA molecule is called a double helix. The double helix structure consists of two strands that are twisted around each other, forming a shape resembling a twisted ladder or spiral staircase. This iconic structure was first described by James Watson and Francis Crick in 1953, revolutionizing our understanding of genetics.
A DNA double helix is made up of two stands that twist around each other in a spiral shape. Each strand consists of a sequence of nucleotide bases that pair up with the bases on the opposite strand, forming the characteristic double helix structure.
The genetic information of an organism is contained in its DNA, which is shaped like a double helix. Each strand of the helix is made up of repeating units called nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.
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.
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.

The pinna (which means "wing" in Latin).
The outer part of your ear is made up of cartilage, which is a tough and flexible connective tissue. This cartilage helps give your ear its shape and structure. Additionally, the outer ear is covered by skin and contains hair follicles and glands that produce earwax.
External ear called pinna
The center of the helix of DNA contains pairs of nitrogenous bases, not nitrogen atoms. These bases are adenine-thymine and guanine-cytosine, which form the genetic code necessary for the functioning of living organisms.
Yes, the helix of the ear contains mechanoreceptors called hair cells that are responsible for detecting mechanical vibrations and converting them into electrical signals that can be interpreted by the brain.
DNA is genetic material in the nucleus that has instructions to allow the cell to perform vital life functions. It is in the shape of a double helix, and contains the bases adenine, thymine, cytosine and guanine. RNA contains the same genetic material and also contains adenine, cytosine and guanine. However, RNA is only a single helix and contains uracil instead of thymine.
Sugar is added to nucleotides in DNA formation. How the sugar binds in the helix formation determines the tightness of the helix, so it will be A form or B form. A form is more condensed and has the feature of sugar pucker.
DNA, which stands for deoxyribonucleic acid, is the macromolecule that contains deoxyribose in its structure. Deoxyribose is a sugar molecule that forms the backbone of the DNA double helix.
Chromosomes are build like that.Nucleus is a large organell with many components.
