Differentiate clearly between primary, secondary, and tertiary protein structure.

section 10 part 5 ds 412 pert technique Steps for developing and solving a PERT schedule : Calculate the expected time for each activity This calculation is based on Beta statistical distribution. Most likely is 4 times more than optimistic and pessimistic estimates. Calculate the variance (ϭ²) of the activities – This is variance of ET Determine the critical path – Critical path is the longest sequence of connected activities throughout the network. This is a path with zero slack time. It is possible to have multiple critical paths. Slack time (ts) is the difference between the earliest expected completion time and the latest exp
