What does a sugar-phosphate and nitrogenous base make?

Explanation: DNA is a polymer composed of nucleotide monomers. Each nucleotide is formed from a deoxyribose sugar, a phosphate, and a nitrogenous base.

What has a phosphate base and sugar?

DNA
DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), or thymine (T).

What nitrogenous base and sugar make up ATP along with the 3 phosphate groups?

adenine
ATP is composed of ribose, a five-carbon sugar, three phosphate groups, and adenine , a nitrogen-containing compound (also known as a nitrogenous base).

Where is sugar and phosphate in DNA?

DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide. The sugar is the 3′ end, and the phosphate is the 5′ end of each nucleiotide.

What is guanine used for?

In the cosmetics industry, crystalline guanine is used as an additive to various products (e.g., shampoos), where it provides a pearly iridescent effect. It is also used in metallic paints and simulated pearls and plastics. It provides shimmering luster to eye shadow and nail polish.

What makes up a phosphate group?

Phosphate group: A functional group characterized by a phosphorus atom bonded to four oxygen atoms (three single bonds and one double bond). One of these oxygen atoms must be bonded to another atom; if not, the structure is a phosphate ion. Generic phosphate group molecular structure. Phosphoric acid.

How many phosphate groups are in one molecule of ADP?

ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atom of ribose.

What is the name of the sugar molecule in the DNA helix?

deoxyribose
The sugar in DNA’s nucleotides is called deoxyribose—DNA is an abbreviation for deoxyribonucleic acid. RNA molecules use a different sugar, called ribose. Covalent bonds join the sugar of one nucleotide to the phosphate group of the next nucleotide, forming the DNA strand’s sugar-phosphate backbone.

What type of molecule is phosphate?

A phosphate group is just a phosphorus atom bound to four oxygen atoms, but it has many important roles. Along with sugars and bases, it makes up nucleic acids, like DNA and RNA. As part of energy carriers, like ATP, it provides energy for moving our muscles.

What kind of molecule is phosphate?

Phosphate, chemical formula PO43-, is a chemical compound made up of one phosphorus and four oxygen atoms. When it is attached to a molecule containing carbon, it is called a phosphate group.

Is sugar a phosphate?

Sugar phosphates, which are phosphoric acid esters of monosaccharides, occur as intermediates in carbohydrate metabolism. Two of these compounds, namely, ribose phosphate and deoxyribose phosphate, are constituents of nucleotides and nucleic acids.

What is a ribose sugar?

Ribose (d-ribose) is a type of simple sugar, or carbohydrate, that our bodies make. It is an essential component of adenosine triphosphate (ATP), which supplies energy to our cells.

What macromolecules have phosphate groups?

The classes of macromolecule that contain the most phosphorus are equally the nucleic acids and the lipids.

Which type of molecule always contains phosphate groups?

Nucleic acids are molecules made up of repeating units of nucleotides that direct cellular activities such as cell division and protein synthesis. Each nucleotide is made up of a pentose sugar, a nitrogenous base, and a phosphate group. There are two types of nucleic acids: DNA and RNA.

Is nitrogen A base?

Nitrogenous base: A molecule that contains nitrogen and has the chemical properties of a base. The nitrogenous bases in DNA are adenine (A), guanine (G), thymine (T), and cytosine (C). The nitrogenous bases in RNA are the same, with one exception: adenine (A), guanine (G), uracil (U), and cytosine (C).

Where is ribose sugar found?

RNA
ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds to nitrogenous bases.

What kind of compound is ribose?

Ribose is a simple sugar and carbohydrate with molecular formula C5H10O5 and the linear-form composition H−(C=O)−(CHOH)4−H. The naturally-occurring form, d-ribose, is a component of the ribonucleotides from which RNA is built, and so this compound is necessary for coding, decoding, regulation and expression of genes.

Which bases are purines?

Nitrogenous bases present in the DNA can be grouped into two categories: purines (Adenine (A) and Guanine (G)), and pyrimidine (Cytosine (C) and Thymine (T)).

Why are purines and pyrimidines called bases?

Adenine and guanine have a fused-ring skeletal structure derived of purine, hence they are called purine bases. … Similarly, the simple-ring structure of cytosine, uracil, and thymine is derived of pyrimidine, so those three bases are called the pyrimidine bases.
