For question 1) The complimentary strand will read in opposite direction 5' to 3', and will have each base replaced by its specific base pair:

Adenine (A) replaced by Thymine (T)

Guanine (G) replaced by Cytosine (C)

Thus, the complimentary strand of 3' ATC GAC CAT 5' read as 5' TAG CTG GTA 3'

For question 2)

Cell membrane is a flexible membrane made up of proteins and lipids, and is role is to

- select the materials absorbed by the cell
