Question

Writing a Full Strand: 1. A. Original DNA: CCT ATA TCT CTC TAT ATC TCT CAT ACT GTG TGT CTC TAT Complementary DNA

Answer 1

The complementary DNA sequence to the given strand CCT ATA TCT CTC TAT ATC TCT CAT ACT GTG TGT CTC TAT is GGA TAT AGA GAG ATA TAG AGA GTA TGA CAC ACA GAG ATA, based on the DNA base pairing rules.

Step-by-step explanation:

To derive the complementary DNA sequence for the original DNA strand you provided: CCT ATA TCT CTC TAT ATC TCT CAT ACT GTG TGT CTC TAT, we apply the base pairing rules that adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). After pairing each base correctly, we can provide the complete complementary strand.

Here's the step-by-step process of determining the complementary DNA sequence:

• For each 'C' on the original strand, place a 'G' on the complementary strand.
• For each 'A' on the original strand, place a 'T' on the complementary strand.
• For each 'T' on the original strand, place an 'A' on the complementary strand.
• For each 'G' on the original strand, place a 'C' on the complementary strand.

Following these rules, the complete complementary strand for the given DNA sequence is GGA TAT AGA GAG ATA TAG AGA GTA TGA CAC ACA GAG ATA. This sequence follows directly from the base-pairing rules mentioned above and is written in the 5' to 3' direction, matching the directionality of the original DNA strand.
