What does it mean when it says that nucleotides are the building blocks of DNA?
DNA is made of chemical building blocks called nucleotides. The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA.
What are the building blocks in DNA?
DNA is a molecule made up of four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). For the two strands of DNA to zip together, A pairs with T, and C pairs with G. Each pair comprises a rung in the spiral DNA ladder.
Which nucleotides are used to build DNA?
Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).
What are ACTG in DNA?
ACGT is an acronym for the four types of bases found in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). The sequence of bases in a portion of a DNA molecule, called a gene, carries the instructions needed to assemble a protein.
What are the building blocks of lipids?
The component building blocks of the lipids found in storage fats, in lipoproteins (combinations of lipid and protein), and in the membranes of cells and organelles are glycerol, the fatty acids, and a number of other compounds (e.g., serine, inositol).
What are the building blocks of DNA quizlet?
DNA is made up of small pieces or building blocks known as nucleotides, which have three components.
What are basic building blocks?
The basic building blocks that make up matter are called atoms. What are the different particles found in atoms? (Answer: electrons, protons and neutrons) Where are they found? (Answer: Protons and neutrons are found in the nucleus, and electrons are found in shells around the outside of the nucleus.)
What are the three nucleotides of the DNA?
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base uracil (U) takes the place of thymine.
What are the 3 parts of nucleotides?
Each nucleotide, in turn, is made up of a nitrogenous base, a pentose sugar, and a phosphate.
What are the 4 types of nucleotides?
DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).
What are the building blocks or monomers of lipids?
The building blocks of lipids are one glycerol molecule and at least one fatty acid, with a maximum of three fatty acids.
