What is the replication of ATTCGGATATTGCACGTACTACGATTG?

Answer 1

Good question!

The new complementary strand after replication would be:

TAA GCC TAT AAC GTG CAT GAT GCT AAC

How did we get there? I find it helpful to first split up the strand into sets of 3 nucleotides (also called bases) because it’s easier to look at. Then you match each letter representing a nucleotide with its complement as follows:

A with T,

T with A,

C with G, and

G with C.

I hope that helps!
