DNA and Proteins (Nat 5 Biology)

How is the genetic information organized into in living cells?

• Chromosomes

• Genes

• Proteins

• Ribosomes

What are chromosomes made up of?

• Ribosomes

• Proteins

• Genes

• Nucleus

What is DNA?

• A double-stranded helix

• A molecule that carries a complementary copy of the code from the DNA in the nucleus to a ribosome

• A complex substance that forms the genes of all living organisms

• A chain carrying molecules called bases

What does DNA carry?

• The genetic information needed to make proteins

• The sequence of bases in the DNA

• The sequence of amino acids in the protein made

• The complementary base pairs

How does DNA exist?

• As a molecule that carries a complementary copy of the code from the DNA in the nucleus to a ribosome

• As a chain carrying molecules called bases

• As a double-stranded helix

• As a complex substance that forms the genes of all living organisms

What are the four different types of bases in DNA?

• Adenine (A), Guanine (G), Thymine (T), Uracil (U)

• Adenine (A), Cytosine (C), Guanine (G), Uracil (U)

• Adenine (A), Cytosine (C), Thymine (T), Uracil (U)

• Adenine (A), Cytosine (C), Guanine (G), Thymine (T)

How are the strands of the DNA helix held together?

• By complementary base pairs

• By hydrogen bonds between bases on each strand

• By proteins

• By ribosomes

Which bases only pair together in DNA?

• A only pairs with G and C only pairs with T

• A only pairs with C and G only pairs with T

• A only pairs with T and G only pairs with C

• A only pairs with T and C only pairs with G

What does the sequence of bases in DNA make up?

• The genetic code

• The sequence of amino acids in the protein made

• The complementary base pairs

• The sequence of bases in the DNA

Where are proteins assembled?

• In the nucleus of living cells

• At ribosomes in the cell cytoplasm

• In the genes of all living organisms

• In the chromosomes
