ATC GCT AAT what is the complementary dna strand for this original strand

Answer 1

To find the complementary DNA strand, you can use the base pairing rules of DNA, which are:

• Adenine (A) pairs with Thymine (T)
• Cytosine (C) pairs with Guanine (G)

Given the original strand:

5'-ATC GCT AAT-3'

The complementary strand can be constructed by pairing each base:

• A pairs with T
• T pairs with A
• C pairs with G
• G pairs with C
• C pairs with G
• T pairs with A
• A pairs with T
• T pairs with A

So the complementary strand would be:

3'-TAG CGA TTA-5'

It's common to write complementary DNA strands in the 5' to 3' direction, so reversing this, the complementary strand in conventional notation would be:

5'-TTA CGC TAG-3'
