What is the purpose of adding foreign dna to a bacterial cell called? a)transformation b)biotechnology c)genetic testingd)nondisjunction

a) transformation

Explanation:

The recombinant DNA molecule produced is introduced into a host organism (such as a bacteria) and can then be replicated. This process is known as transformation, in which bacterial cells capture DNA from the external environment.

Host cells copy the vector DNA along with the DNA itself, creating multiple copies of the inserted DNA. Some examples of host cells are the bacteria Escherichia coli and Bacillus subtilis and the yeast Saccharomyces cerevisiae.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
