What is a beneficial association between the roots of a plant and a fungus?
Gnom [1K]

Answer: Mycorrhiza

Explanation: Mycorrhiza is a symbiotic relationship between a plant and a fungi. Nearly 80 percent of all plants with root systems participate in this mutualistic relationship. In mycorrhiza, the fungus forms a haustoria that penetrates the cell walls of the plant's roots. The fungus absorbs all the nutrients from the roots as they are transported to the plant. In return, the fungus gives the plant necessary chemicals and minerals that it cannot properly reach on its own.

Dmitriy789 [7]

Answer:

DNA → ​​TACCATGGAATTACT

RNA → AUGGUACCUUAAUGA

PROTEIN → Methionine-Valine-Proline-Stop codon-Stop codon (AUG GUA CCU UAA UGA)

Explanation:

In nucleic acids (i.e., DNA and RNA), base complementarity refers to the interaction between antiparallel strands. In the double helix DNA molecule, adenine always interacts with thymine (uracil in RNA), while cytosine always interacts with guanine. Moreover, amino acids are encoded by codons, i.e., triplets of nucleotides in the messenger RNA (mRNA). Finally, stop codons are triplets of mRNA nucleotides (e.g., UAG, UAA, UGA) that indicates the end of the protein-coding sequence.
