In blue-white screening, what do blue colonies represent?
Basile [38]

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.

In the initial days of pregnancy, a woman often feels no symptoms at all. Women with ectopic pregnancies often
tatiyna

Answer:

See explanation.

Explanation:

The initial days and even weeks of pregnancy may happen without a woman being aware of the pregnancy. Even though the baby grows quickly, it starts out as just a fertilized egg. So it takes a while to be noticed. And there is plenty of room at first.

But with an ectopic pregnancy, the baby attaches, instead of in the uterus, outside of the uterus. In most cases, the baby attaches inside the fallopian tube. Outside of the uterus is not designed to provide support and space for the baby. As growth occurs, it can cause severe problems. This is dangerous and can cause bleeding, pain, and possibly shock of the woman's condition is not identified and treated.  

Hope this helps! Have an awesome day!! :-)

"In genetic modifications, DNA inserted can come from _____ ." any organism containing the DNA of interest only the same plasmid
liq [111]

Answer:

<h2> any organism containing the DNA of interest</h2>

Explanation:

  • Such type of process in which the modification of the genes of the organisms takes place is known as genetic modification and also called genetic manipulation or genetic engineering.
  • In such type of the process, the branch of biological science that is known as biotechnology is used.
  • In this mechanism, genes of interest are separated from the certain organism and then this gene of interest is inserted into the host organism and such type of DNA that is formed after the addition of foreign genes or DNA is called recombinant DNA.
  • Such type of DNA is used in the production of genetically modified organisms and some other fields for the benefit of human beings.

A red blood cell will shrink in size when placed in a more concentrated salt solution because of the passive process called
Leto [7]
This process is called osmosis whereby water exits the cell through its selectively permeable membrane and into the salt solution to dilute and balance the pressure caused by the concentrated salt solution.
