Which two of the following statements
about protein synthesis are FALSE?
The sequence of amino acids in a polypeptide is specified by
ribosomal RNA.
Genes and the polypeptides they encode are colinear: that is,
the order of missense mutations in a recombination map is the same
as the order of the affected amino acids.
In eukaryotic cells, polypeptide synthesis takes place on
ribosomes in the cytoplasm.
Proteins are always translated as linear polypeptides, beginning
from the amino terminus, but may be cleaved or joined
afterward.
The sequence information in proteins can be transferred back
into DNA by reverse transcriptase.
According to the "sequence hypothesis", the structure and
properties of a protein are determined by its
primary amino-acid sequence.
