Which best describes the role of mRNA in protein synthesis?
mRNA brings amino acids to the ribosome where they are connected to construct a protein.
mRNA forms the peptide bonds connecting amino acids together to construct a protein.
mRNA decodes the sequence of tRNA into the amino acids used to construct a protein.
mRNA brings the code of DNA to the ribosome where it is used to construct a protein.
Which is a way that RNA differs from DNA?
uracil base
3-stranded
no phosphate group
connected by peptide bonds

GCA TCC TAC
AUG CUU CGU
ATG CTT CGT
GCA UCC UAC
Which best describes the process of translation?
Translation occurs within the nucleus.
Translation involves copying a DNA strand.
An mRNA strand is produced by the process of translation.
A growing protein chain is produced by the process of translation.
Use the codon chart below to answer the question. Which shows the translated amino acid chain for the code AUG GCC UAC?
Methionine, Alanine, Tyrosine
Isoleucine, Alanine, Tyrosine
Methionine, Alanine, Stop
Isoleucine, Alanine, Stop
What is the function of transfer RNA?
It is a part of the ribosome.
It delivers the correct amino acid to the ribosome.
It bonds to other RNA molecules, leading to their destruction.
It carries the information coding for the amino acid sequence of a protein.
How are the amino acids linked together during translation?
by creating peptide bonds
by creating hydrogen bonds
by creating covalent bonds
by creating phosphate bonds
A segment of mRNA contains the following codons AUG CAA GGU GAG. Which are the complementary tRNA anticodons?
TAC GTT CCA CTC

UAC GUU CCU GUG
AUG CAA GGA GAG
Which is affected by the order of amino acids?
