#### DNA Molecule Structure and Base Pairing The DNA molecule consists of two complementary strands that are held together by hydrogen bonds between their nucleotide bases. The four nucleotide bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in a specific manner: A always pairs with T, and C always pairs with G. This is known as base pairing. #### Determining the Sequence of the Second DNA Strand To determine the sequence of the second DNA strand based on the given sequence of the first strand, we need to apply the rules of base pairing. In the given sequence, the nucleotides are represented as follows: First DNA strand: T A G A C T G G T A C G T To find the sequence of the second DNA strand, we need to pair each nucleotide with its complementary base. Applying the base pairing rules, we get: Second DNA strand: **A T C T G A C C A T G C A** #### Counting the Number of Nucleotides and Fragment Length To calculate the number of nucleotides of each type and the length of the DNA fragment, we can count the occurrences of each nucleotide in the given sequence. In the given sequence, we have: - Adenine (A): 4 occurrences - Thymine (T): 4 occurrences - Cytosine (C): 2 occurrences - Guanine (G): 4 occurrences Therefore, the number of nucleotides of each type in the DNA molecule is: - Adenine (A): 4 - Thymine (T): 4 - Cytosine (C): 2 - Guanine (G): 4 The length of the DNA fragment can be calculated by adding up the number of nucleotides in both strands. In this case, since each strand has 10 nucleotides, the total length of the DNA fragment is 20 nucleotides. I hope this helps! Let me know if you have any further questions.
