Aminoacyl-trna synthetases recognize their specific amino acid by and recognize the trnas that carry it by the

Aminoacyl-tRNA synthetases recognize their specific amino acid by charge, size and R group and recognize the tRNAs that carry it by the nucleotide sequence .

Aminoacyl-tRNA synthetases are enzymes that attaches the appropriate amino acids on to its tRNA . These are also responsible for performing the first step of protein synthesis.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
