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).

Furthermore, 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.

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.

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 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 are the building blocks of a lipid?

Answer and Explanation: The building blocks of lipids are one glycerol molecule and at least one fatty acid, with a maximum of three fatty acids. Glycerol is a sugar alcohol with three OH groups.

What are the correct base pairing rules for DNA?

The rules of base pairing (or nucleotide pairing) are:

  • A with T: the purine adenine (A) always pairs with. the pyrimidine thymine (T)
  • C with G: the pyrimidine cytosine (C) always pairs with. the purine guanine (G)
  • 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 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 components of the DNA and RNA molecules?

    The other type of nucleic acid, RNA, is mostly involved in protein synthesis. Just like in DNA, RNA is made of monomers called nucleotides. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar called ribose, and a phosphate group.

    What are the building blocks of the DNA molecule?

    Nucleotides. The basic building block of DNA is called a NUCLEOTIDE. A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases.

    Which are the components the 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 makes up the backbone of a DNA strand?

    (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). (A grouping like this of a phosphate, a sugar, and a base makes up a subunit of DNA called a nucleotide.)

    What can be joined together in any order in DNA?

    Nucleotides may be joined in any order. A DNA nucleotide is a unit made of a nitrogenous base, a 5-carbon sugar called deoxyribose, and a phosphate group. DNA has four kinds of nitrogenous bases: adenine, guanine, cytosine, and thymine.

    What is the backbone of the DNA made of?

    A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

    Why is Chargaff’s law important in regards to solving the structure of DNA?

    Chargaff’s rules turned out to be an important clue in this puzzle. Biologists had long known that DNA was built out of four molecules: adenine, guanine, thymine and cytosine. Chargaff’s rules are important because they point to a kind of “grammar of biology”, a set of hidden rules that govern the structure of DNA.

    What is the basic structure of a DNA molecule?

    DNA structure. 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).

    How is DNA a code for traits?

    The genetic code dictates which proteins the cell manufactures. Proteins are strands of amino acids. The sequence of nucleotides in DNA genes determines the order of amino acids in a protein. First an enzyme transcribes a gene to an intermediate biochemical called ribonucleic acid, or RNA.

    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.

    What scientists are credited to the base pairing rules?

    B. BASE PAIRING: 1962: James Watson and Francis Crick discovered that A always bonds with T and C bonds with G. Adenine and thymine are complementary. They both require 2 hydrogen bonds.

    What are the four letters in a DNA molecule and what do they represent?

    The possible letters are A, C, G, and T, representing the four nucleotide bases of a DNA strand — adenine, cytosine, guanine, thymine — covalently linked to a phosphodiester backbone.

    What are the two sides of the DNA ladder made of?

    The shape of DNA is a double helix, which is like a twisted ladder. The sides of the ladder are made of alternating sugar and phosphate molecules. The sugar is deoxyribose. The rungs of the ladder are pairs of 4 types of nitrogen bases.

    What is the shape of a DNA strand?

    double helix

    What forms the rungs of the ladder?

    They showed that alternating deoxyribose and phosphate molecules form the twisted uprights of the DNA ladder. The rungs of the ladder are formed by complementary pairs of nitrogen bases — A always paired with T and G always paired with C.
