Question

cells that contain the same dna can make different proteins. protein - coding dna determines traits, while non - coding dna has no known function. the majority of human dna contains instructions to make proteins. the nucleotide sequence of a gene determines the amino acid sequence of a protein. the genetic code refers to the set of rules used to build proteins from genes. the genetic code is specific to humans.

Explanation:

1. Cells with the same DNA can make different proteins due to processes like gene regulation. For example, in multicellular organisms, different cell - types express different subsets of genes. So, this statement is True.
2. Non - coding DNA has many functions such as regulating gene expression, so the statement that it has no known function is False.
3. Only a small fraction of human DNA codes for proteins, so the statement that the majority of human DNA contains instructions to make proteins is False.
4. The nucleotide sequence of a gene is transcribed and translated to determine the amino - acid sequence of a protein, so this statement is True.
5. The genetic code is the set of rules for translating the information in genes into proteins, so this statement is True.
6. The genetic code is nearly universal across all living organisms, not specific to humans, so this statement is False.

Answer:

1. True
2. False
3. False
4. True
5. True
6. False
