DNA REPLICATION AND PROTEIN SYNTHESIS

If a strand of DNA had bases in the following order - ATCCGTC, what would be the replicated complementary strand?

• UAGGCAG

• ATCCGTC

• TAGGCAG

• TUGGCTG

If a strand of DNA had bases in the following order - ATCCGTC, what would be the transcribed mRNA sequence?
