IMPORTANCE OF CARBOHYDRATES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The order of the base pairs in a strand of DNA is important because:
A
an organism can only survive if the base pairs are in the correct sequence.
B
it forms a code that tells a cell which protein to make.
C
it forms a code that tells a cell how to reproduce
D
None of the above:the order of base pairs doesn’t matter
Explanation: 

Detailed explanation-1: -The sequence of basis on the DNA molecule is what directs the sequence of amino acids in the protein molecule-that’s how it all links together! So, the sequence of bases in DNA codes for the sequence of amino acids of a protein.

Detailed explanation-2: -The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.

Detailed explanation-3: -Answer and Explanation: The right answer to this question is that “The sequence of DNA that codes for a protein and thus determines a trait is called a gene".

Detailed explanation-4: -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-5: -Determining the order of the nucleotides within a gene is known as DNA sequencing.
