A strand of DNA contains the sequence GGC-CAT. What is the complementary strand of mRNA for this sequence?

GGC-CAT - strand of DNA xxx- xxx - strand of mRNA
The first, let's see what connect with what: when we talk about DNA and complementary strand of DNA: guanine connects to cytosine (and vice versa) thymine connects to adenine (and vice wersa)
when we talk about DNA and complementary strand of RNA: guanine connects to cytosine (and vice wersa) adenine (in DNA) connects to uracil (in RNA) thymine (in DNA) connects to adenine (in RNA)
GGC- CAT - strand of DNA CCG- GUA - complementary strand of mRNA
complementary strand of DNA would be: CCG- GTA (in complementary strand of RNA: thymine is replaced with uracil)

CCG-GUA :) (because its an mRNA strand it can't have the amino acid Thymine or (T) so we replace it with a U.

The complementary mRNA strand for the DNA sequence GGC-CAT is CCG-UAC. This pairing occurs with G pairing with C, and A pairing with U instead of T. It is important to remember that RNA is synthesized in the 5' to 3' direction, following the base pairing rules.
