What is the primary purpose of rRNA?
It carries amino acids to the ribosome during protein synthesis.
It forms the core of the ribosome and helps catalyze protein synthesis.
It carries the genetic message copied from DNA to the ribosome.
It copies an entire DNA molecule before cell division.
What is the primary purpose of mRNA?
It carries the genetic message from DNA to the ribosome.
It brings specific amino acids to the growing polypeptide.
It is an enzyme that replicates DNA before mitosis.
It packages proteins for secretion from the cell.
What is the primary purpose of tRNA?
It serves as the structural and catalytic component of ribosomes.
It delivers the correct amino acids to the ribosome according to the mRNA codons.
It stores genetic information as a double helix.
It transports finished proteins to the Golgi apparatus.

Name the process shown in the left diagram and identify what it starts with and what it produces.
Transcription: starts with DNA and produces mRNA
Translation: starts with mRNA and produces a protein
Replication: starts with DNA and produces two DNA molecules
Transduction: starts with viral DNA and produces bacteriophages
Name the process shown in the right diagram and identify what it starts with and what it produces.
Transcription: starts with DNA and produces mRNA
Translation: starts with mRNA and produces a protein
Replication: starts with DNA and produces two DNA molecules
Transformation: starts with plasmid DNA and produces recombinant bacteria
Choose the option that correctly fills the labels from left to right in the diagram: [DNA double helix] → [single-stranded nucleic acid] → [folded purple product].
Use the word bank to complete the statements by matching each definition to the correct term. Word Bank (use each once): Stem, Specialized, Activated, Deactivated, Gene Regulation.
Stem
Cells that can change into many different types of other cells
Specialized
Cells with a specific function
Activated
A gene being “turned on”
Deactivated
A gene being “turned off”
Gene Regulation
Control of which genes are turned on or off in specific cells
Use the word bank to complete the statements by matching each definition to the correct term. Word Bank (use each once): Transcription, Translation, Protein, Environmental Factors.
Transcription
Process that makes mRNA from a DNA template
Translation
Process that builds a polypeptide using an mRNA template
Protein
Product that provides traits in the organism
Environmental Factors
Influences such as temperature and diet that can affect gene activity
(a) cells can change into many different types of (b) cells with a specific function. The genes in each cell can be "turned on" aka (c) or "turned off" aka (d) .
In eukaryotic cells, when a gene is turned on, it undergoes (a) to make mRNA and then (b) to generate proteins which provide traits. Keep in mind however, that (c) like temperature, diet, etc. can also affect the (d) of specific genes.
