There are 20 different tRNA molecules, one for each of the 20 amino acids found in protein
There are 20 different tRNA molecules, one for each of the 20 amino acids found in protein. During protein synthesis, the job of a tRNA molecule is to carry its particular amino acid to the growing protein chain and find the correct amino acid position there. It does this by matching a 3- letter anticodon on the tRNA to a complementary 3-letter codon on mRNA. Below, in a diagram of a ERNA molecule, nucleotides are represented by small circles, some...

Place the following steps of TRANSLATION in the correct order for EUKARYOTES. The ribosome reaches a stop codon. A release factor binds and causes the release of the new polypeptide, along with the mRNA. The ribosome dissociates. v Acharged tRNA with a matching anticodon binds the mRNA codon in the A site. ✓ The ribosome moves exactly 3 nucleotides toward the 3* end of the mRNA. The small ribosomal subunit uses rRNA to bind to the Kozak sequence, which places...

Polymerization of amino acids into a polypeptide requires energy. In terms of chemical thermodynamics, the chemical energy for peptide bond formation in translation technically comes from: hydrolysis of GTP hydrolysis of ATP translocation of the ribosome as it moves along the mRNA ribosomal RNA (rRNA) secondary structure transcription of the mRNA that is being translated Transfer RNA (tRNA) is a ribonucleic acid about 50-60 nucleotides long. When a tRNA gets "charged" by covalent addition of its cognate amino acid, to...

Question 9:
The genetic code is read in groups of three nucleotides, called
codons, in mRNA that specifies for a particular amino acid.
tRNA molecules act as the amino acid carriers that by correctly
pairing with the codon on mRNA can deliver the correct amino acid
to the ribosome during translation. At the tip of each tRNA
molecule is a group of three nucleotides called an anticodon and at
the other end is where the corresponding amino acid is attached...
