DNA

Front

What are the two molecules that form the sides (backbone) of the DNA ladder?

Back

Deoxyribose sugar and phosphate.

Front

What happens to a protein when it is denatured?

Back

It loses its shape.

Front

What happens when an enzyme is heated to a high temperature?

Back

The shapes of the enzyme are altered or denatured.

Front

What best explains the interaction between tRNA and mRNA during translation?

Back

Anticodons on the tRNA line up with complementary codons on the mRNA.

Front

How many amino acids are coded for by the nucleotide sequence ATG GGA ACT CCA?

Back

4.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What are nucleotides made of?

Back

A phosphate group, a deoxyribose sugar, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the role of DNA polymerase?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of mRNA?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.
