Question

Replicate the given strand of DNA

5'-ATG CCT ATG AGA CTA TAC-3

Answer 1

To replicate the given DNA segment (5'-ATG CCT ATG AGA CTA TAC-3'), the complementary strand is 5'-GTA TAG TCT CAT AGG CAT-3', following base pairing rules where A pairs with T and C pairs with G.

Step-by-step explanation:

The student has asked about the replication of a DNA strand, specifically the identification of the complementary sequence for a given DNA segment. DNA replication involves the generation of a complementary strand based on the sequence of nucleotides in the original strand, following the base pairing rules:

• Adenine (A) pairs with Thymine (T)
• Cytosine (C) pairs with Guanine (G)

To replicate the given DNA segment 5'-ATG CCT ATG AGA CTA TAC-3', we must start by identifying the complementary nucleotides for each base in the sequence:

1. A (Adenine) pairs with T (Thymine)
2. T (Thymine) pairs with A (Adenine)
3. G (Guanine) pairs with C (Cytosine)
4. C (Cytosine) pairs with G (Guanine)

Therefore, the complementary sequence of the given strand, written in the 5' to 3' direction, is:

5'-GTA TAG TCT CAT AGG CAT-3'

It's important to note that the replication process involves enzymes like DNA polymerase, which synthesize the new strand by adding nucleotides complementarily to the template strand.
