Understanding the Basics
* DNA: Deoxyribonucleic acid, the genetic material in most organisms. It has two strands that are complementary and run in opposite directions (antiparallel).
* RNA: Ribonucleic acid, involved in protein synthesis. It has one strand.
* Base Pairing: DNA and RNA use specific base pairing rules:
* Adenine (A) pairs with Thymine (T) in DNA and Uracil (U) in RNA
* Guanine (G) pairs with Cytosine (C)
The Process
1. Replace Thymine (T) with Uracil (U): In RNA, uracil (U) replaces thymine (T).
2. Flip the sequence: Since the mRNA strand is complementary to the DNA strand, we need to flip the sequence to get the correct order.
Applying it to the Sequence:
1. DNA: ggcataggt
2. Replace T with U: ggcauaggt
3. Flip the sequence: tggtacgca
Therefore, the mRNA strand for the given DNA sequence is: tggtacgca
