(1) Cells contain DNA that controls the production of proteins.
(2) DNA is composed of proteins that carry coded information for how cells function.
This would be correct IF it said that DNA is composed of NUCLEIC ACIDS instead of protiens. DNA is not COMPOSED of Proteins - DNA CODES for proteins.
(3) Proteins are used to produce cells that link amino acids together into DNA.
(4) Cells are linked together by proteins to make different kinds of DNA molecules.
(3) Proteins are used to produce cells that link amino acids together into DNA.
(4) Cells are linked together by proteins to make different kinds of DNA molecules.
(#3 and #4 are just INCORRECT)
What are genes
composed of?
(1) offspring (2) DNA (3) cells (4) traits (this would be correct if the question was what do genes CODE for)
