Explanation:

• Question 38: In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). For the sequence ATTGTCC, the complementary bases are TAACAGG.
• Question 39: For the sequence ATGTGCC, the complementary bases are TACACGG (A - T, T - A, G - C, T - A, G - C, C - G, C - G).
• Question 40: The process where one strand serves as a template for the replication of a new strand in DNA replication is called semi - conservative replication. But among the options given, the key concept here is that one strand is a template (semi - conservative implies each new DNA molecule has one old and one new strand, which is based on one strand being a template).

Answer:

Question 38: A. TAACAGG
Question 39: D. TACACGG
Question 40: (Assuming the intended answer is semi - conservative, but since it's not an option, perhaps there is a mis - labeling. However, based on the description of one strand as a template, the closest in the options context is semi - conservative. But if we strictly go by the options given in a general sense of the process description where one strand is a template, the answer related to the concept is semi - conservative. But since the options for 40 are not fully clear in the problem (maybe a typo in options), if we assume the options are as presented and we go by the basic definition of one - strand - as - template, the answer is semi - conservative (but if forced to choose from a wrong option list, there is an error. But typically, the process is semi - conservative)
