Answer:
<h2>D. Radioactive nitrogen in the DNA of the bacterial cells is present in one strand of the DNA of all of the cells.</h2>
Explanation:
As given here,
The nitrogenous base of DNA is radio active labeled, and is grown in normal unlabeled medium.
As we know that DNA replication occurs in semi-conservative way, so after one round of replication, one parental strand would be radio active and other newly synthesized strand would be unlabeled.
So here, after one round of replication, one strand of all the newly synthesized DNA would be radio active and other strand would be normal.
The answer is electrostatic precipitator
hope this helps :)
Answer:
they are heterotrophic and can produce their own food unlike things like microbes who rely on other things to live. they are also multicellular unlike most bacteria (mushroom is an exception)
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.'
