Answer:
In the most general case of x bases and y bases per codon, the total number of possible codons is equal to xy .
In the case of the hypothetical Martian life-forms, is the minimum codon length needed to specify 17 amino acids is 5 (25 = 32), with some redundancy (meaning that more than one codon could code for the same amino acid). For life on Earth, x = 4 and y = 3; thus the number of codons is 43, or 64. Because there are only 20 amino acids, there is a lot of redundancy in the code (there are several codons for each amino acid).
Explanation:
Answer:
dicots
Explanation:
The stem is a thin stem that has no secondary growth in monocotyledons. It occurs, for example, in grasses. When the stem plant has secondary growth, this plant is usually a dicotyledonea. In addition to the stem, the plants have other structures such as trunk, stalk, strain and stem.
The trunk is a stem thickened by secondary growth and is typical of most trees. Stolen is a stem that grows close to the ground, as is the case with strawberries. The stem is a cylindrical stem without branches, typical of palm trees. The stem is also a branchless stem, but it has nodes distributed along its length. An example is the bamboo stem.
