DNA and RNA each have 4 bases, 3 of which are common to both and 1 that differs.
DNA has Thymine, Adenine, Cytosine, Guanine
RNA has Uracil, Adenine, Cytosine, Guanine
The substrates used in the DNA synthesis reaction are deoxyribonucleoside triphosphates (dNTPs), which are the building blocks of DNA.
Uracil. Uracil is not present in DNA, but it is present in RNA. DNA's "equivalent" base is thymine, meaning when DNA is transcribed into RNA, the places where thymine would go instead has uracil.
During protein synthesis, DNA serves as a template for mRNA to be transcribed. The mRNA base pairs with the complementary DNA strand, forming a sequence that codes for specific amino acids. This mRNA sequence is then translated by ribosomes to assemble the corresponding protein.
One difference between DNA and RNA is that DNA has a nitrogen base pyrimidine thymine that connects with purine adenine. In RNA, thymine is replaced by another pyrimidine called uracil.
mRNA (messenger RNA) is a copy of DNA that carries the genetic information from the DNA to the ribosome, where it serves as a template for protein synthesis. The sequence of nucleotides in the mRNA molecule determines the sequence of amino acids in the protein being synthesized.
In the synthesis of mRNA, an adenine in the DNA pairs with uracil. This is known as A-U base pairing, which replaces the A-T base pairing found in DNA replication.

Synthesis of new DNA
Uracil. Uracil is not present in DNA, but it is present in RNA. DNA's "equivalent" base is thymine, meaning when DNA is transcribed into RNA, the places where thymine would go instead has uracil.
DNA synthesis is also known as DNA replication.
The base uracil is a nitrogenous base in RNA used for protein synthesis. It replaces Thymine from DNA.

DNA synthesis or DNA replication
Mutations are the result of an error in the duplication process of DNA. These include insertion errors in DNA (base-pairing, dimers), DNA silencing, abnormal protein synthesis, and defective chromosomes.
Two strands of DNA are used to make complementary strands of DNA. One original strand serves as a template for the synthesis of a new strand, resulting in a double-stranded DNA molecule with base pairing between the original and newly synthesized strands.
