If a tRNA had an AGC, it could base-pair to a(n).

A. areolar, cartilage:Areolar connective tissue is highly vascularized, providing nutrients and support to surrounding tissues. In contrast, cartilage is avascular, relying on diffusion from surrounding tissues for nutrients and waste removal.

B. dense regular connective; dense irregular connective:Both dense regular and dense irregular connective tissues have limited vascularization, so this pair does not accurately reflect a highly vascular versus nonvascular comparison.

C. nervous; bone:Nervous tissue has some blood supply but is not considered highly vascular compared to connective tissues. Bone is highly vascularized, containing Haversian canals, so this pair is reversed.

D. epithelial; skeletal muscle:Epithelial tissue is avascular and relies on underlying connective tissue for nutrient diffusion, while skeletal muscle is highly vascularized to meet metabolic demands.

A. RNA:RNA is a general term for ribonucleic acid and includes several types with different functions. It does not specifically refer to the RNA that delivers amino acids to the ribosome.

B. mRNA:Messenger RNA carries the genetic code from DNA to the ribosome, directing the sequence of amino acids in a protein, but it does not transport the amino acids themselves.

C. sRNA:Small RNA molecules (sRNA) are involved in regulatory processes within the cell, such as gene silencing, and are not responsible for delivering amino acids for protein synthesis.

D. tRNA:Transfer RNA is responsible for bringing specific amino acids to the ribosome during translation. Each tRNA recognizes codons on the mRNA and ensures that the correct amino acids are added to the growing polypeptide chain.
