Answer:
b. False
Step-by-step explanation:
Kozak consensus sequence acts as translation initiation site and is involved in the initiation of translation process.
The sequence is 5'-(gcc)gccRccAUGG-3' . AUG in the sequence is start codon and codes for methionine. It is highly conserved. R denotes a purine which means that it can be either adenine or guanine. Significance of bases inside brackets have not been properly confirmed.
Hence, the statement that Kozak consensus sequence defines the location of the transcriptional start site is false.
