The genetic code is said to be "degenerate" becauseA. A single tRNA may couple a single mRNA codon to multiple amino acids. B. A
Grace [21]

Answer:

The correct answer is option C. "A single tRNA specific for a particular amino acid may respond to multiple codons in an mRNA".

Explanation:

Genetic code is said to be "degenerate" because there are more codons than amino acids, which is possible because a single tRNA specific for a particular amino acid may respond to multiple codons in an mRNA. tRNA recognize the codons of the mRNA by a specific nucleotide sequence called anticodon, however the nucleotide sequence of the anticodon can recognize more than one codon sequence. This phenomenon takes place at the third position of the codon and is known as "wobble".

3. What can you say about the general relationship of the charge of the anion to the subscript of the cation?
Genrish500 [490]

Answer:

Cations are positively charged ion while anions are negatively charged ions formed by loosing and gaining of electrons respectively. Transition metals are metals in the middle of the periodic table with multiple oxidation states. The charge on the transition metal is equal to the oxidation state which varies from +1 to +7. The charge of transition metal can also be determined in neutral compound as long as one knows the charge or the oxidation state of the other atom in the compound. The charge of transition can also be determined in the case of neutral complexes where the transition element has combined with other atoms to form molecular complexes that are either positively or negatively charged, e.g. MnO4-. Lastly Neutral transition metal compounds which are soluble in water have a charge of +3 or less than+3.
