Homework Answers
1. Answer: Option C
is correct
Explanation:
The Western blotting utilizes a specific antibody to detect the
expression of proteins.
In the given case, the beta-tubulin expression is checked by using
a specific antibody.
All samples exhibited the band at the same location
= All tissues express beta-tubulin and the size is similar
2. Answer: Option D is correct
Explanation:
Fertilization involves the fusion of an egg cell with the
sperm.
The egg cell provides the cytoplasm and DNA.
The sperm cell provides only DNA.
