Final answer:
To replicate the given DNA strand, each nucleotide is matched with its complementary base, following base pairing rules. The correct new strand for the given sequence would be 'TGT TAT ATC GAA AAC TGC CCC TTG GGT AAT', which is option A
Step-by-step explanation:
The process of replicating a DNA strand involves matching each nucleotide with its complementary base according to base pairing rules. These rules specify that adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). In the given sequence, the new DNA strand should be the complement of the original strand, meaning wherever there is an A in the original, there should be a T in the new strand, and vice versa. The same rule applies for G and C pairs.
Therefore, the replication of the presented DNA sequence 'ACA ATA TAG CTT TTG ACG GGG AAC CCO ATT' (ignoring the typo 'CCO') would yield a new strand with the sequence 'TGT TAT ATC GAA AAC TGC CCC TTG GGT AAT' which corresponds to option A).
