Question

The primary building blocks of DNA are
A)Nitrogenous base, phosphorus, and ribose
B)Nitrogenous base, sulphur, and deoxyribose
C)Nitrogenous base, phosphorus, and deoxyribose
D)Nitrogenous base, sulphur, and ribose

Answer 1

Hint: The DNA is made up of four types of molecules. These molecules are also called the base and they are attached to a sugar-phosphate backbone. DNA has four bases which are Adenine (A), Guanine (G), Cytosine (C), and Thymine (T). These bases pair across the two strands of the helix i.e Adenine pairs with Thymine, and Cytosine pairs with Guanine.

Complete answer:
The biological instructions that make a species unique are contained in Deoxyribonucleic acid. The instructions are passed from adult organisms to their offspring during reproduction.
-The chemical building blocks of DNA are nucleotides. These nucleotides are made up of three parts - a phosphate group, a sugar group, and one of four types of nitrogen bases.
-the nucleotides linked together to form a strand of DNA, with the phosphate and sugar group.
-The nitrogen bases have four bases which are adenine (A), thymine (T), guanine (G), and cytosine (C). The patterns of these bases determine what biological instructions are stored in a strand of DNA

Additional Information: -DNA is found in the cell called nucleus in all the eukaryotic organisms. A DNA molecule is tightly packaged and this package form of DNA is called chromosomes.
-DNA unwinds during the replication which helps make it possible to be copied. It also unwinds so that instructions can be utilized to make proteins.
-DNA is in compact chromosomes form to allow transfer to new cells during cell division.

So, the correct answer is,” Nitrogenous base, phosphorus, and deoxyribose”.

Note: -For the organisms to survive, reproduce, and develop DNA is important because it contains instructions that are needed for all these processes.
-The sequences of each DNA consist of instructions to make protein known as a gene.
