What is the “backbone” of DNA composed of? Phosphate molecules and deoxyribose sugar. DNA backbones are made up of deoxyribose, a pentose sugar. These sugars are connected via a phosphodiester bond.

Read the full answer

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).

Beside this, What is DNA made of quizlet?

They are made of a 5-carbon sugar (deoxyribose), a phosphate group, and a nitrogenous base bound to the sugar. The four different types of nucleotides are adenine (A), thymine (T), guanine (G) and cytosine (C). Deoxyribose makes up the backbone of the DNA double helix when two molecules of DNA bind together.

Likewise, What is the backbone of DNA made up of?

deoxyribose

Also, What is DNA made of?

DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.

What is a DNA quizlet?

Dna. a double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited traits of organisms and viruses.

What three components make up DNA quizlet?

Three components that make up DNA structure. Phosphate, nucleobase, deoxyribose sugar.

What is the backbone of DNA made of?

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).

Where does DNA come from?

Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.

What atoms is DNA made of?

It consists of just a few kinds of atoms: carbon, hydrogen, oxygen, nitrogen, and phosphorus. Combinations of these atoms form the sugar-phosphate backbone of the DNA — the sides of the ladder, in other words. Other combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G).

Where is the DNA made?

Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Is DNA made of carbon?

A single basic unit or “building block” of DNA consists of a sugar , a phosphate group and a base. Sugars are rings of carbon and oxygen atoms. The sugar in DNA has 5 carbon atoms (labelled 1′ – 5′), and is called deoxy-ribose (hence the “Deoxy-ribo” in DNA).

What is the backbone of DNA composed of?

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).

Is DNA composed of atoms?

DNA, which stands for deoxyribonucleic acid, resembles a long, spiraling ladder. It consists of just a few kinds of atoms: carbon, hydrogen, oxygen, nitrogen, and phosphorus. … Other combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G).
