In the A/T site, the A-site half resides in the small ribosomal subunit where the mRNA decoding site is located. The mRNA decoding site is where the mRNA codon is read out during translation. The T-site half resides mainly on the large ribosomal subunit where EF-Tu or eEF-1 interacts with the ribosome.
Secondary cloverleaf structure of tRNA Phe from yeast.. The cloverleaf model of tRNA is a model that depicts the molecular structure of tRNA. [1] The model revealed that the chain of tRNA consists of two ends—sometimes called "business ends"—and three arms.
Ribonuclease T (RNase T, exonuclease T, exo T) is a ribonuclease enzyme involved in the maturation of transfer RNA and ribosomal RNA in bacteria, [2] as well as in DNA repair pathways. [3] It is a member of the DnaQ family of exonucleases and non- processively acts on the 3' end of single-stranded nucleic acids .
Research into the stability of aa-tRNAs illustrates that the acyl (or ester) linkage is the most important conferring factor, as opposed to the sequence of the tRNA itself. This linkage is an ester bond that chemically binds the carboxyl group of an amino acid to the terminal 3'-OH group of its cognate tRNA. [ 7 ]
The synthetase first binds ATP and the corresponding amino acid (or its precursor) to form an aminoacyl-adenylate, releasing inorganic pyrophosphate (PPi).The adenylate-aaRS complex then binds the appropriate tRNA molecule's D arm, and the amino acid is transferred from the aa-AMP to either the 2'- or the 3'-OH of the last tRNA nucleotide (A76) at the 3'-end.
In today's puzzle, there are six theme words to find (including the spangram). Hint: The first one can be found in the top-half of the board. Here are the first two letters for each word: OV. SI ...

The T-arm has two components to it; the T-stem and the T-loop. The T-stem consists of a series of paired nucleotides, typically 5 pairs, but sometimes as few as 1 or as many as 6. [1] [2] The T-loop is also often known as the TΨC arm due to the presence of ribothymidine (T/m5U), pseudouridine and cytidine residues. It folds into a unique ...
