Functions of cell surface Receptors .
most ligands responsible for cell-cell signaling ( including neurotransmitters, peptide, hormones, and growth factors) bind to receptors on the surface of their target cells. 
        
             
        
        
        
b. Natural selection is an example of the major mechanism by which evolution occurs
Explanation:
The concept of evolution are both closely related in that natural selection is the major mechanism by which evolution occurs. This was proposed by Charles Darwin after his journey to the Galapagos Island on the HMS Beagle. 
- Evolution is the change in the characteristics of an organism over several generations. 
- Organisms evolved to in order to be at an advantage and naturally favored.
- According to Charles Darwin, organisms evolved by the process of natural selection. 
- Natural selection is the process by which an organism becomes adapted to its environment. 
- Organisms with desirable trait are naturally favored with competitive and reproductive advantage in the environment.

Answer:
Initiator proteins.
Explanation:
DNA replication may be defined as the process of formation of daughter DNA strand from the template parental strand. Three main process of DNA replication are initiation, elongation and termination.
The bacterial DNA is fail to replicate in yeast cells because the DNA is not able to show initiation in yeast cells. Initiation process is important to start the DNA replication. The specific proteins and polymerase are required in different organism. There is problem in initiation proteins that fails to initiate  DNA replication.
Thus, the answer is initiator proteins.
