Here I provide you some examples of modified stems:
<u>Bulb:</u> discoid stems that have a single apical bud surrounded by numerous cataphiles, and in their part I have adventitious roots. Its function is the reserve.
<u>Tuber</u>: They are portions of stems with irregular growth, which forms tuberosities due to the large accumulation of reserve substances.
<u>Cladodes: </u>are flattened stems, very thick, green leaves look alike and have photosynthetic function.
<u>Stem tendrils:</u> they are filamentous stems, which can be rolled up so that the plant can climb grasped of various objects, which is useful when the plant needs to look for the greatest possible luminosity, especially in areas where shadows predominate.
Phylloclades: Stems sheet form with limited growth, like a leaf, green and photosynthetic color.
The correct answer is: A. by the sequence of nitrogenous bases
The genetic code is the set of rules which is represented by the specific order of nucleotide bases. It is used by cells to translate information encoded within genetic material (DNA) into proteins. The genetic code consists of nucleotide triplets-codons, specify which amino acid will be added next during protein synthesis.

Answer: These external agents of genetic change are called mutagens. Exposure to mutagens often causes alterations in the molecular structure of nucleotides, ultimately causing substitutions, insertions, and deletions in the DNA sequence.
Explanation: Point mutations are a large category of mutations that describe a change in single nucleotide of DNA, such that that nucleotide is switched for another nucleotide, or that nucleotide is deleted, or a single nucleotide is inserted into the DNA that causes that DNA to be different from the normal or wild type gene
