Answer:
When directed mutagenesis which is also called reverse genetics is used, only a single mutation per genome is introduced. In contrast, the number of mutations per genome introduced by random mutagenesis is usually difficult to control. It is likely that the strain you obtained with a mutation in gene X after random mutagenesis contained an additional mutation or perhaps multiple mutations which ultimately was/were responsible for loss of virulence in your favorite pathogen.

hi here is your answer hope it helps or then sry
Explanation:
the importance of oxygen for animals, researchers suspected that a sudden increase in the gas to near-modern levels in the ocean could have spurred the Cambrian explosion.
Answer:
This question is incomplete as it lacks options. However, it can be answered based on general knowledge of the DNA structure.
Hydrogen bonds in a DNA are located between the nucleotides that holds the double stranded DNA molecules.
Explanation:
Deoxyribonucleic acid (DNA) is the genetic material in living cells. The DNA molecule is made up of nucleotides monomers. However, since the DNA molecule is double-stranded, the nucleotides are of two chains composed of four nucleotide subunits viz: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).
The two chains of nucleotides in a DNA molecule are called strands. Each strand is bonded to one another by the nucleotides using complementary base pairing i.e. A-T, G-C. The bonds between the nucleotidew of each strand is called HYDROGEN BOND.
Hence, HYDROGEN BONDS in a DNA molecule is located in between two nucleotides of each strand. That is, hydrogen bond holds Adenine to Thymine and Guanine to Cytosine.
<span>Fossils, or the fossilized remains of an animal, tend to be bones which are made of much denser materials than flesh. Since a jellyfish has no bones, a bony fish is more likely to leave a fossil.</span>
