DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which sequence of mRNA bases would pair with this partial strand of DNA:ATG TGA CAG
A
ATG TGA CAG
B
UAC ACU GUC
C
GTA AGT GAC
Explanation: 

Detailed explanation-1: -Solution : (c) Adenine always pairs with thymine and cytosine always pairs with guanine. Thus, sequence of bases on complementary strand would be TACGTACGT.

Detailed explanation-2: -ATG TGA CAG Explanation: Adenine(A) pairs with thymine(T) and vice versa while guanine(G) pairs with cytosine(C) and vice versa. The bases are complementary, always appearing opposite to each other on the DNA double helix.

Detailed explanation-3: -DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together.

Detailed explanation-4: -Adenine pairs with thymine, and cytosine pairs with guanine. The sequence of bases in a portion of a DNA molecule, called a gene, carries the instructions needed to assemble a protein.
