1. Describe the changes in clarity and viscosity of a nuclear suspension that occurs upon the addition of Sodium Dodecyl Sulfate (SDS)? Why do they changes occur?

2. Thymus cells have a relatively small amount of cytoplasm and this feature makes thymus tissue ideal for DNA extraction. Why?

1. Describe the changes in clarity and viscosity of a nuclear suspension that occurs upon the addition of Sodium Dodecyl Sulfate (SDS)? Why do they changes occur?

After adding SDS, the solution becomes very viscous and more translucent. This change occurs because SDS is a detergent and dissolves cell membranes and denatures proteins. The release of DNA and other cellular matter due to SDS-induced lysis causes the ...

Solution Summary

The expert describes the changes in clarity and viscosity of a nuclear suspension that occurs upon the addition of Sodium Dodecyl Sulfate. The basic cellular events that occur in an onion root zone with the highest peroxidase activity.
