1

What does a codon consist of?

Two nucleotides in DNA.

Single amino acid code.

One nucleotide sequence.

Three nucleotides in mRNA sequence.

1

What role do tRNA molecules play?

They encode DNA information.

They splice introns from mRNA.

They bring amino acids to the ribosome.

They create mRNA sequences.

1

What pair of bases is found in mRNA?

Thymine pairs with Uracil.

Guanine pairs with Cytosine.

Adenine pairs with Uracil, not Thymine.

Adenine pairs with Thymine.

1

Which molecule contains codons?

Messenger RNA (mRNA) carries codons.

Transfer RNA (tRNA).

Ribosomal RNA (rRNA).

DNA in the nucleus.

1

What does the sequence of codons determine?

The design of tRNA molecules.

The sequence of DNA replication.

The order of amino acids in a protein.

The structure of ribosomes.

1

What occurs during the elongation phase of translation?

Ribosome detaches from mRNA

Amino acids are sequentially added to the polypeptide chain

Stop codon is recognized

tRNA is replaced by mRNA

1

What signals the end of translation?

Recognition of a stop codon

Disassembly of ribosome

Start codon recognition

Amino acid shortage

1

How is mRNA translated into protein?

By pairing codons with complementary tRNA anticodons

Through DNA ligation

By reversing RNA to DNA

During RNA replication

1

How does termination of translation occur?

Releases factors recognize stop codons on mRNA.

Ribosome moves backwards on mRNA.

A loop forms in the mRNA.

tRNA stops binding to mRNA.

1

Which molecule carries the template for translation?

DNA transfers code to ribosomes.

mRNA carries the genetic code from DNA.

tRNA brings amino acids in order.

rRNA synthesizes proteins directly.
