If a life-form has six different bases-ABCDEFG. the percentage composition of A,B and C is same as EFG. Hypothesis the structure of the nucleic acid.
To hypothesize the structure of the nucleic acid, we need to analyze the information provided.
We know that the life-form in question has six different bases: A, B, C, D, E, and F, represented by the letters ABCDEFG. Additionally, we are told that the percentage composition of A, B, and C is the same as E, F, and G.
Let's proceed step by step in hypothesizing the structure:
Step 1: Analyzing the percentage composition:
Since the percentage composition of A, B, and C is the same as E, F, and G, it indicates that A is paired with E, B is paired with F, and C is paired with G.
Step 2: Determining the structure of the nucleic acid:
Based on the traditional structure of nucleic acids, we know that they consist of two complementary strands forming a double helix. In DNA, A always pairs with T (adenine and thymine), and C always pairs with G (cytosine and guanine).
Applying this knowledge to our hypothesis:
Since A is paired with E and C is paired with G, we can assume that A and E represent adenine-thymine base pairs, and C and G represent cytosine-guanine base pairs.
Therefore, based on the information provided, the hypothesis for the structure of the nucleic acid in this life-form could be that A always pairs with E (adenine-thymine), B with F, C with G (cytosine-guanine), and D is an independent base.
It's important to note that this is a hypothetical structure based solely on the given information, and further experimental evidence would be required to confirm the actual structure of the nucleic acid in this life-form.
