Please follow forum rules next time.

2.1   Your topic/question title must be as descriptive as possible using less than 80 characters. Avoid vague topic titles such as "need help", "Homework Help!", "PLEASE HELP!!!!", etc. Topics with these titles will be ignored.

The last because that is the way you read a strand of DNA, in the 5' to 3' direction.

The synthesis of a strand of DNA is in the 5’ to 3’ direction.
