Which statement best describes the relationship that exists among proteins, DNA and cells
DNA is made up of proteins, which tell a cell how to function.
Proteins are made up of DNA, which determines the cells that are produced.
Proteins combine to produce cells, which produce DNA
Cells contain DNA, which controls the production of proteins.
Which part of the DNA molecule determines an organism's traits?
hydrogen bonds
phospholipid group
sugar-phosphate backbone
complementary base pairing
What is the relationship between an organism's DNA and protein produced?
DNA becomes a specific part of the protein structure.
DNA translates proteins into amino acids.
DNA determines the amino acid sequence of each protein.
DNA determines the ribosomal RNA sequence that becomes part of the protein structure.
Which describes the role of mRNA in protein synthesis?
mRNA brings the amino acids to the ribosome where they are connected to construct a protein
mRNA forms the peptide bonds connecting amino acids together to construct a protein
mRNA decodes the sequence of tRNA into the amino acids used to construct a protein
mRNA brings the code of DNA to the ribosome where it is used to construct a protein
What process is represent at Point 3?
transcription
replication
translation
mutation
What is the three base sequence attached to tRNA? (It pairs with mRNA using the base-pair rule.)
codon
anticodon
protein
