Question

DNA has two strands. If the sequence of nucleotides of one strand was known, is it possible to use that information to determine the sequence of the second strand? Explain your reasoning for your response using an example DNA sequence.

Answer 1

Answer:Yes!

Step-by-step explanation:

it is possible to find out the sequence of the second DNA strand if we know the first strand of nucleotides. DNA strands are complementary to each other, meaning the nucleotides on one strand pair specifically with their complementary nucleotides on the other strand. This relationship is defined by the base pairing rules: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

For example, let's say we have the sequence of one DNA strand as follows:

Strand 1: 5'-ATCGGCTA-3'

Based on the base pairing rules, we can determine the sequence of the second strand by matching complementary nucleotides:

Strand 2: 3'-TAGCCGAT-5'

The second strand is generated by pairing adenine (A) with thymine (T), cytosine (C) with guanine (G), and so on. By knowing the sequence of one DNA strand, we can deduce the complementary sequence of the other strand. (Hope this helps!)
