Given the following template DNA strand, what is the correct complementary DNA sequence?

3' CGC AGT GGA CAT TTC 5'

 

**Question**: Given the following template DNA strand, what is the correct complementary DNA sequence?  
3' CGC AGT GGA CAT TTC 5'

**Options**:  
- O 5' GCG TCA CCT GTA AAG 3'  
- O 5' GAA ATG TCC ACT GCG 3'  
- O 5' GCG UCA CCU GUA AAG 3'  
- O 5' GAA AUG UCC ACU GCG 3'  

**Explanation**: 
The task is to determine the complementary DNA sequence for the given template strand. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, the complementary sequence for the given strand (3' to 5') should be constructed by writing from 5' to 3'. 

The correct complementary sequence is:
5' GCG TCA CCT GTA AAG 3'

The third and fourth options contain incorrect bases, showing RNA nucleotides (U instead of T).

Expert Solution
Step 1

Nucleic acids are present inside the nucleus to store and pass genetic information and thus controls the overall functions of the cell. DNA is a double-stranded molecule. The two strands are complementary to each other.

The DNA( Deoxyribonucleic acid) is made up of repeating units of the nucleotides. A nucleotide has three components:

  • Deoxyribose sugar 
  • Nitrogenous base 
  • Phosphate
