What is the structure of DNA called?

A molecule of DNA consists of two strands that form a double helix structure. DNA is a macromolecule consisting of two strands that twist around a common axis in a shape called a double helix.

Which of the following describes a DNA molecule?

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA’s instructions, or genetic code.

Which best describes the structure of the backbone of a DNA molecule?

Which of the following best describes the structure of the DNA “backbone”? The individual nucleotides in each DNA strand are held together by covalent bonds linking together their sugar and phosphate groups. The two strands are held together in the middle by hydrogen bonds linking complementary bases.

What is DNA explain?

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

Can DNA be created?

Why do boogers taste sweet?

Research has shown that mucus also plays a role in our sense of smell: it is believed to help attach molecules them to scent receptors. It achieves this by being coated in hundreds of oligosaccharide molecules, which are a type of sugar, making boogers sweet.

Why do kids pick their nose and eat it?

Most kids pick their noses and eat the boogers because they taste salty. Try using positive reinforcement to help stop this behavior. In other words, don’t scold your child for picking and/or eating boogers. Instead, try praising them when he/she uses a tissue to blow or clean out their nose.
