Translation does not always follow the linear model. Messenger RNAs can host multiple open-reading frames when several start codons are detected in the gene by the ribosomes. If the ribosome encounters a stop codon while translating, it can stop translating while not disengaging the amino-acid string. A new start codon can then restart translation.
The gene for the protein RAD52 has multiple start codons within the gene. Which of the following would be predicted based on this gene?
a. The protein would exist in multiple forms with different lengths.
b. The mRNA for the protein could not be transcribed into a tRNA molecule.
c. The frame would be altered, causing different proteins to be created from the same tRNA.
d. The gene will also have multiple stop codons placed at similar spacing to the start codons.
