Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Nitrogenous bases are located on both strands of the DNA double helix. What is the significance of the nitrogenous bases?
A
The number of adenines and cytosines determines the type of RNA that will be produced.
B
The order of nitrogenous bases determines the order of amino acids in the proteins synthesized.
C
The amount of thymine and guanine in the DNA molecules determines the length of the genes.
D
The type of hydrogen bonding between the nitrogenous bases determines which amino acid will be added to the peptide chain.
Explanation: 

Detailed explanation-1: -A set of five nitrogenous bases is used in the construction of nucleotides, which in turn build up the nucleic acids like DNA and RNA. These bases are crucially important because the sequencing of them in DNA and RNA is the way information is stored.

Detailed explanation-2: -What is the Main Purpose of the Sequences of Nitrogenous Bases in DNA? The nitrogenous bases are like the foundation of DNA and RNA which is collectively known as Nucleic acids. The main purpose of sequences of nitrogenous bases in DNA is to store the genetic information of the organisms in them.

Detailed explanation-3: -The double-helix shape allows for DNA replication and protein synthesis to occur. In these processes, the twisted DNA unwinds and opens to allow a copy of the DNA to be made. In DNA replication, the double helix unwinds and each separated strand is used to synthesize a new strand.

Detailed explanation-4: -Nitrogenous bases are located on both strands of the DNA double helix. What is the significance of the nitrogenous bases? The number of adenines and cytosines determines the type of RNA that will be produced. The order of nitrogenous bases determines the order of amino acids in the proteins synthesized.
