What is the complementary sequence for sequences 1. and 2. shown     below.NOTE:  Please remember DNA has polarity-the sequence needs to be written in 5′ (read five prime) to 3′(read three prime) direction.  For example:

The complement of 5′-AGCT-3′ is not TCGA, because as written this means 5′-TCGA-3′,  but 3′-TCGA-5′.  Convention has it that we write the complementary sequence from 5′ to 3′, so you reverse 3′-TCGA-5′ to  5′-AGCT-3′, which is the correct answer.

1. 5′-AATTAA-3′
2. 5′-GGCCGGCC-3′
3. 3′-ATAT-3′
4. 3′-TTAACC-5′
