Base (biología)

The video tutorial explains the structure of DNA, focusing on the base pairs that form the genetic code. It details how adenine pairs with thymine and cytosine pairs with guanine, and how the sequence of these bases (A, T, C, G) constitutes the genetic code.

What are the bonds between the two DNA strands made of?

• Proteins

• Sugars

• Bases

• Lipids

Which base does adenine always pair with in DNA?

• Thymine

• Cytosine

• Guanine

• Uracil

Which base pairs with guanine in DNA?

• Uracil

• Adenine

• Thymine

• Cytosine

What is the significance of the order of bases A, T, C, and G in DNA?

• It determines the DNA's color

• It affects the DNA's weight

• It forms the genetic code

• It creates the DNA's shape

Which of the following is NOT a base found in DNA?

• Adenine

• Cytosine

• Uracil

• Thymine
