What are the three parts that make up the building blocks of DNA?

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.
A.

What are the three main components of a DNA molecule?

DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.
  • What are the chemical components of a DNA nucleotide?

    Scientists needed to determine if genes were in proteins or DNA. DNA is a polymer of nucleotide monomers, each consisting of a phosphate, a deoxyribose sugar, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G), or cytosine (C).
  • What are the three parts of a DNA nucleotide?

    Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts:
    • Nitrogenous Base. Purines and pyrimidines are the two categories of nitrogenous bases.
    • Pentose Sugar. In DNA, the sugar is 2'-deoxyribose.
    • Phosphate Group. A single phosphate group is PO43-.
  • What are the names of the four bases in DNA?

    In DNA, there are four different bases: adenine (A) and guanine (G) are the larger purines. Cytosine (C) and thymine (T) are the smaller pyrimidines. RNA also contains four different bases. Three of these are the same as in DNA: adenine, guanine, and cytosine.
B.

What are the three basic parts or molecules that make up the building blocks of DNA?

DNA is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).
  • What are the basic building blocks of proteins?

    The basic building block of a protein is called an amino acid. There are 20 amino acids in the proteins you eat and in the proteins within your body, and they link together to form large protein molecules.
  • What is the name of the sugar that is present in the DNA molecule?

    2 — A 5 carbon sugar, deoxyribose (hence the name deoxyribonucleic acid). There are two sugars found in nucleic acids; ribose is found in RNA (ribonucleic acid) and deoxyribose in DNA. Deoxyribose refers to the fact that one of the hydroxyl (OH) groups is missing from this sugar.
  • What are the chemical components of a DNA molecule?

    DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous basesadenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.
C.

Which are the components of DNA molecule?

These three components are described below. 1 – A Phosphate group is negatively charged and gives DNA molecules a negative charge. O P O O- O- R Page 2 2 2 – A nitrogen base – Four different nitrogen bases are found in DNA. They are adenine (A), cytosine (C), guanine (G) and thymine (T).
  • What is a DNA strand made of?

    The two DNA strands are called polynucleotides since they are composed of simpler monomer units called nucleotides. Each nucleotide is composed of one of four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A] or thymine [T]), a sugar called deoxyribose, and a phosphate group.
