1. In order for protein synthesis to occur, mRNA must migrate to the
ribosomes
lac operon
RNA polymerase
heterochromatin
2. Transfer RNA acts as an "interpreter" because it
carries an amino acid to its correct codon
synthesizes amino acids as they are needed
produces codons to match the correct anticodons
converts DNA into mRNA
3. During translation in eukaryotes, anticodons
never bind to the mRNA codons
assist in the assembly of fats
consist of a five-nucleotide sequence at one end of the transfer RNA molecule
ensure that each amino acid is delivered to its proper "address" on the mRNA
4. During translation, the amino acid detaches from the transfer RNA molecule and attaches to the end of a growing protein chain when
the ribosomal RNA anticodon binds to the messenger RNA codon
the transfer RNA anticodon binds to the messenger RNA codon
a "stop" codon is encountered
the protein chain sends a signal through the nerve cells to the brain
5. Translation takes place
in the nucleus of the cell
inside the mitochondria
at the ribosomes
within the layers of the cell membrane
6. In translation, the information encoded in the ______ is used to assemble proteins.
tRNA
rRNA
mRNA
7. As amino acids are added to the protein chain, they are held together by
peptide bonds
hydrogen bonds
covalent bonds
ionic bonds
8. Initially, every polypeptide chain formed in translation begins with the amino acid
tryptophan
glutamic acid
methionine
threonine
9. A ribosome has
one binding site for DNA
three binding sites used during translation
four binding sites for tRNA
no binding sites since the proteins must detach
10. More than one ribosome may carry out translation at the same time on one RNA strand. Therefore,
many more tRNA molecules are needed
more mRNA transcripts are required
fewer copies of the mRNA are needed
fewer proteins are produced
