DNA, RNA, and Protein Synthesis

A portion of mRNA is coded CUG. The corresponding DNA is coded

• GAC

• GTC

• CTG

• CAG

A portion of DNA reads GAG. The corresponding mRNA would be

• GUG

• GTG

• CTC

• CUC

DNA polymerase and RNA polymerase are similar in that they

• are both enzymes

• both are involved in making new molecules

• both can be found doing work in the cell nucleus

• all of these things are true

The process of creating RNA using DNA as the template is

• translation
• transcription
• translocation
• Transylvania

In RNA, uracil takes the place of the DNA nitrogen base called

• guanine
• cytosine
• thymine
• adenine

What is a codon?

• a sequence of 3 amino acids
• a sequence of three nitrogen bases
• a sequence of 3 enzymes
• a sequence of 3 proteins

Which type of RNA delivers the genetic code to the ribosome?

• tRNA
• mRNA
• rRNA
• tmRtmRNA

What is the function of transfer RNA?

• It is a part of the ribosome.
• It bonds to other RNA molecules, leading to their destruction.
  
• It delivers the correct amino acid to the ribosome.
• 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 phospate bonds
