Answer:
The correct option is : cells containing empty plasmid vectors
Explanation:
The blue-white screen is a technique which involves the rapid identification of the recombinant bacteria in a vector-based molecular cloning experiment. In this method, a DNA ligated vector is inserted in a host cell which is viable for transformation and grown in presence of X-gal.
The cells that are transformed with the vectors having the recombinant DNA produce the white colonies. Whereas, the cells transformed with empty vector i.e. the non-recombinant plasmids, produce the blue colonies.
Answer:
The correct answer will be- Cargo vesicles
Explanation:
The product of the gene expression is known as the protein which is formed as the result of the transcription and translation.
The process of translation takes place in the ribosomes attached to the endoplasmic reticulum after which the proteins enter the lumen of the endoplasmic reticulum.
The protein then enters the secretory pathway which represents the movement of proteins by packaging them in cargo vesicles attached with the cargo proteins.
Thus, Cargo vesicles are the correct answer.
During asexual reproduction
The answer should be 4) as it is known that uv radiation might have an effect on dna, thus causing mutations such as skin cancer in humans.
Homeostasis is the process by which organisms keep internal conditions relatively constant<span> despite changes in external environments. Homeostasis in the body is maintained by feedback loops.
