First step  build the table (<span>see attached table)
</span> using a calculator we find the regression line

Number of values=9

Regression line equation

Y=a+bx

y-intersection a= - 0.1697

<span>slope b=0.0187</span>

y=-0.1697+0.0187X

Darya [45]

Answer:

Option A , Genome

Explanation:

Microarrays that contains array of single stranded DNA are used to study thousands of gene expression for all the genes of a genome and are usually termed as DNA miscroarrays. These microarrays being single stranded allows attachment of complementary DNA strand to bind to their surface. The mRNA from the cell is extracted and converted into cDNA which is further used for DNA cloning.

Hence, option A is correct
