There are only about 40 different tRNAs in a cell even though 61 codons code for amino acids. This discrepancy can be attributed to the fact that the first nucleotide in the anticodon can base-pair with more than one nucleotide in the codon. This phenomenon is known as and is, in part, due to and the presence of at this position in some tRNA molecules.

The correct answer is - wobble; the curvature of the anticodon loop; inosine.

Explanation:

The wobble phenomenon or hypothesis tells that why there are multiple codons are present for a single amino acid. 20  amino acids are coded by 61 codons. It states that tRNA can identify and attach to more than one amino acid due to the curvature of the anticodon loop.

The curvature of the anticodon loop is that the base at the 1st position on the anticodon to binding but the less-precise base pairs that can arise between the 3rd base of the codon. The inosine is the nucleoside that presents in a position in the curvature of the anticodon loop and its position responsible for wobble as well.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
