What do blocks of 3 DNA bases make?

To conclude, nucleotides are important as they form the building blocks of nucleic acids, such as DNA and RNA. Nucleotides are made up of 3 parts. The first is a distinct nitrogenous base, which is adenine, cytosine, guanine or thymine. In RNA, thymine is replaced by uracil.

Similarly, what are the basic building blocks of DNA and RNA?

The structure of RNA differs fundamentally from that of DNA in three ways: It forms a single strand sugar-phosphate chain. The sugar in its nucleotides is ribose. The base thymine is replaced by the base uracil.

What is the basic building block of a 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.

How many building blocks are there in 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.
