A double-stranded dna molecule is 25,000 base pairs long. How many complete turns are there in the molecule?
siniylev [52]

Double-stranded DNA molecule is 25,000 base pairs has 2500 turns are there in the molecule.

Double-stranded DNA includes  polynucleotide chains whose nitrogenous bases are related via hydrogen bonds. within this arrangement, every strand mirrors the other because of the anti-parallel orientation of the sugar-phosphate backbones, as well as the complementary nature of the A-T and C-G base pairing.

Different animal DNA viruses which all mirror within the mobile nucleus, poxviruses reflect their double-stranded DNA within the cytoplasm of the host mobile. Virus debris are manufactured inner subcellular factories known as inclusion bodies.

explanation;

Number of turns in and DNA molecule will be = total base pairs / 10.

                                                                             = 25,000 /10

                                                                              = 2500

LuckyWell [14K]

Answer:

Mouth

Explanation:

The mouth is the part of the upper digestive tract where the process of mechanical digestion begins. Teeth breakdown the food into smaller pieces. With help of tongue, the food pieces are mixed with saliva which in turn is released from salivary glands. This process of mechanical digestion of food is called chewing or mastication. It converts the food into a soft, flexible, easily swallowed mass called a bolus. Food particles in bolus get dissolved in water to facilitate the chemical digestion by enzymes.
