The six nucleotides preceding the start codon and the first nucleotide after the

Question

The six nucleotides preceding the start codon and the first nucleotide after the start codon in eukaryotes exhibit strong sequence preference as determined by the percentages of nucleotides in the -6 to -1 positions and the +4 position. Use the data given in the table to determine the six nucleotides that most commonly precede the start in vertebrates. Express your answer as a sequence of nucleotides separated by dashes. Example: 5'-C-A-T-G-...-3' Use the data given in the table to determine the nucleotide that most commonly follows the start in vertebrates. T C G A The 7 nucleotide sequence that consists of the three consensus nucleotides before the AUG (-3 to -1) and the one after the AUG (+4) has been named after the scientist who first described it. What is the name of this sequence?

Explanation / Answer

Part A 5'-G-C-C-A-C-C-3' is kozac sequence.

PART B: answer is G as it proceeds the START CODON ATG in many of the vertebral species whose sequences have been given
