Answer:
Option). the uneven cutting by most restriction enzymes
Explanation:
Sticky ends can be defined as over-hanged DNA fragments of unequal length, having a terminal portion with unpaired nucleotides. These fragments are formed by a staggered cut on DNA molecules wit the help of restriction endonuclease enzymes.
These ends have complementary nucleotide bases that allow complementary base pairing between bases, and thus, known as sticky ends.
Thus, the correct answer is 'last option.'
It gets its nourishment from its mother. The human embryo is connected to its mother by a placenta through which materials are passed.
Answer:
E. Fecal coliforms will likely contain enzymes to counteract toxic oxygen forms.
D. Fecal coliforms will need to acquire trace elements for growth in the lake environment.
C. The lake environment will support the growth of facultative anaerobes.
Explanation:
For the growth and multiplication of bacteria following factors are important required in their environment;
- trace elements
- oxygen
- nutrients
Answer: The same amount of bacteria is dependent variable
Two types of variables are used to do an experiment, independent variable and dependent variable. The variable which is used to test the effect on dependent variable is called an independent variable and the variable which is being tested and measured is called a dependent variable. In the given experiment, the same amount of bacteria is dependent variable, which is being tested and measured. The different temperature is independent variable.
