Describe the structural features that all tRNA molecules have in common.

Describe how tRNA is charged with an amino acid.

Describe the specificity between the amino acid carried by a tRNA and a codon in mRNA.

The attachment of an amino acid to a tRNA is called

Describe how tRNAs function in the context of the ribosome in buildinga polypeptide.

Outline the key structural features of RNA.

Which of the following is NOT a general feature of tRNA? A. All TRNAS contain 4 loops, the anticodon loop, the hydroxy-uridine and methylcytosine loops and a variable loop B. The tertiary structure of tRNAs is L-shaped C. All ERNAS contain anti-codons D. All TRNAS contain amino acids attached to the 3'-OH end E. All ERNAS contain the rare nucleotides, hydroxyuridine and methyl cytosine

Which part of a cell is the tRNA produced?

One remarkable feature of the genetic code is that amino acids with similar chemical properties often have similar codons. thus codons with U or C as the second nucleotide tend to specify hydrophobic amino acids. Can you suggest a possible explanation for this phenomenon in terms of the early evolution of the protein-synthesis machinery?

3)Which of the following statements are true? Choose all that apply a)There are multiple codons possible for nearly all amino acids b)Each stop codon also codes for an amino acid c)Each tRNA will base pair with only one codon d)The start codon also codes for an amino acid e)Each codon in mRNA codes for exactly one amino acid f)Each codon in tRNA codes for exactly one amino acid g)Each anticodon in tRNA pairs with exactly one codon h)Each tRNA carries exactly one type of amino acid
