Which of the following nitrogenous bases is only found in RNA?

• Adenine

• Thymine

• Cytosine

• Uracil

• Guanine

During DNA Replication, the synthesis of DNA on the lagging strand takes place in segments, these segments are called _____________.

• Okazaki Fragments

• DNA Chunks

• Polymerase Fragments

• Double Helix Fragments

When the DNA double helix is going through Replication, the process is known as semi-conservative for which of the following reasons?

• DNA Replication is semi-conservative because the new DNA disappears and the old DNA remains intact.

• DNA Replication is semi-conservative because all of the original DNA strands are lost and only new DNA remains.

• DNA Replication is semi-conservative because 1 of the new double helices has the original DNA and the other double helix has only the new DNA.

• DNA Replication is semi-conservative because each new double helix contains 1 original strand and 1 new strand.

A DNA sequence is shown below. TAGGAGCAT What is produced when the sequence is transcribed?

• A chain of three amino acids

• A set of three tRNA molecules

• A section of DNA with the base sequence of ATCCTCGTA

• A section of mRNA with the base sequence of AUCCUCGUA

A small portion of an mRNA sequence is shown below. AAUGACUGGCUC Starting with the first base, how many codons does this portion of the sequence contain?

• 1

• 4

• 6

• 12

A codon is necessary in the process of translation because it codes for a

• Specific nitrogen base

• Specific amino acid

• Specific anticodon

• Specific tRNA molecule

What would terminate translation?

• The arrival of a transfer RNA molecule to the A site of the ribosome

• The transcription and processing of a new RNA molecule

• The arrival of the ribosome to a stop codon, such as UGA

• The attachment of a complementary codon to another codon

The function of _____ is to transport amino acids in the cytoplasm to the ribosome.

• rRNA
