Question
Which of the following statements about bases are true?Each base pair is a geneBases are small moleculesHuman DNA contains four types of baseAny combination of bases can form a base pair
Solution
The correct statements about bases are:
-
Bases are small molecules: This is true. In the context of DNA, bases refer to the molecules that make up the DNA structure. These are adenine (A), thymine (T), guanine (G), and cytosine (C).
-
Human DNA contains four types of base: This is also true. The four types of bases in human DNA are adenine, thymine, guanine, and cytosine.
The incorrect statements about bases are:
-
Each base pair is a gene: This is false. A gene is a segment of DNA that contains the instructions to make a specific protein (or part of a protein). Genes can be made up of hundreds or thousands of base pairs, not just one.
-
Any combination of bases can form a base pair: This is false. In DNA, adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C). This is known as base pairing rule or Chargaff's rule.
