Match the following terms to their definitions. match the words in the left column to the appropriate blanks in the sentences on the right. make certain each sentence is complete before submitting your answer. words can be used more than once. messenger rna ribosomal rna synthetase enzymes transfer rna atp 1. : forms part of the subunits for the protein synthesizing organelle. 2. : a molecule that binds to a specific codon and specific amino acid simultaneously. 3. : attaches the correct amino acid to its transfer rna. 4. : provides the energy needed for synthesis reactions. 5. : produced in the nucleus, this molecule specifies the exact sequence of amino acids of the protein to be made. 6. : may be attached to the er or scattered in the cytoplasm.

1. Forms part of the subunits for the protein-synthesizing organelle. - Ribosomal RNA.

2. A molecule that binds to a specific codon and specific amino acid simultaneously. - Transfer RNA.

3. Attaches the correct amino acid to its transfer RNA. - Synthetase enzymes.

4. It provides the energy needed for synthesis reactions. - ATP

5. Produced in the nucleus, this molecule specifies the exact sequence of amino acids of the protein to be made. - Messenger RNA

6. May be attached to the ER or scattered in the cytoplasm. - Ribosomal RNA.

Important notes:

- Messenger RNA is also written as mRNA

- Transfer RNA is also written as tRNA

- About point number 6:

To be more accurate, it is the whole ribosome that can be attached to the ER or scattered in the cytoplasm. However, because the ribosome is made of proteins and Ribosomal RNA, then it is also true that Ribosomal RNA can be attached to the ER or scattered in the cytoplasm. Although "synthetase enzymes" could be another option for this point, it is not accurate to say that synthetase enzymes, in general, could be attached to the ER or scattered in the cytoplasm because there are other synthetase enzymes in other places besides the cytoplasm or the Endoplasmatic Reticulum (ER).

is this a psat question, if so do not cheat try your best.
