Question

Can someone help me with this question. Thank you A consensus sequence is a series of bases or types of bases commonly found at a specific position in the genomes of multiple individuals. The two types of bases are purines (R) and pyrimidines (Y). The following table shows the nucleotide sequence of a region of gene X from six different individuals Nucleotide positions are labeled 1 through 7. 12345 7 Individual 1 T A T GA A Individual 2 T A TTAA Individual 3 TCCTGA Individual 4 TA CTA Individual 5 T A AA G A Individual 6 TC ATAAA Compare the sequences of all six individuals to determine the consensus sequence for this region of gene X. O TAYTRAA O TATTGAA O TARTYAA O TCYARAT O TAYTAAA

Explanation / Answer

According to the given defination of consensus sequence,

Nucleotide position 1 has commonly occuring base as T

Nucleotide position 2 has commonly occuring base as A

Nucleotide position 3 has more probability of pyrimidine bases T and C so, commonly occuring base as pyrimidine (Y)

Nucleotide position 4 has commonly occuring base as T

Nucleotide position 5 has equal probability of A and G, hence commonly occuring base is purine (R)

Nucleotide position 6 has commonly occuring base as A

Nucleotide position 7 has commonly occuring base as A

sequence: TAYTRAA
