If DNA has a strand with a sequence of GCT-ACC-AAT-GCG, the replicated DNA strand would be:
|
|
GCG-TAA-CCA-TCG
|
|
|
CGA-UGG-UUA-GCG
|
|
|
CGA-TGG-TTA-CGC
|
|
|
CGG-TAA-TAA-CGC
|
Explanation:
Detailed explanation-1: -(c) Adenine always pairs with thymine and cytosine always pairs with guanine. Thus, sequence of bases on complementary strand would be TACGTACGT.
Detailed explanation-2: -Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine. This means that the two strands are complementary to each other. For example, a strand of DNA with a nucleotide sequence of AGTCATGA will have a complementary strand with the sequence TCAGTACT (Figure 9.8).
