• alleles

• chromosomes

• proteins

What two main processes are involved in how the genetic code is read by enzymes to produce proteins in an organism?

• Replication and Mutation

• Transcription and Translation

• Mitosis and Meiosis

• Photosynthesis and Respiration

What are the special portions of a chromosome that code for different things called?

• Nucleosomes

• Base pairs

• Genes

• Proteins

What is the product of the transcription process?

• DNA

• Messenger RNA (mRNA)

• Protein

• Ribosome

RNA is different from DNA because it has

• ribose sugar and thymine

• ribose sugar and uracil

• deoxyribose sugar and uracil

• deoxyribose sugar and thymine

Which of the following is a key difference between mRNA and DNA?

• mRNA contains deoxyribose sugar, while DNA contains ribose sugar.

• mRNA contains thymine, while DNA contains uracil.

• mRNA is typically double-stranded, while DNA is single-stranded.

• mRNA contains ribose sugar and uracil, while DNA contains deoxyribose sugar and thymine.

After transcription and processing, where does the mRNA move to for translation?

• The nucleus

• The mitochondrion

• The cytoplasm, to find a ribosome

• The cell membrane

Each codon codes for a specific ___________?

• protein

• gene

• amino acid

• allele

In translation, what is a codon?

• A specific amino acid.

• A set of three bases on the mRNA that codes for a specific anticodon.

• A transfer RNA (tRNA) molecule.

• The entire reading frame of the mRNA.

Choose the correct pairing:

• transcription: DNA -> mRNA

• translation: DNA -> mRNA

• translation: DNA -> Protein

• transcription: mRNA -> Protein
