What is a gene?
A strand of DNA that serves as an instruction manual for how to make necessary proteins for the body
A strand of DNA that acts as a 3D printer
A notable feature or quality in a person
What are genes made up of?
DNA
Ribosomes
mRNA
tRNA
Where are genes located in the cell?
Chromosomes
What are chromosomes?
Compact units in which double helices are packaged into
Compact units in which DNA are packaged into
Compact unites in which mRNA are packaged into
What percentage of an organism's chromosomes are inherited from each of the organism's parents (in sexually reproducing organisms)?
30%
40%
50%
60%
What is a trait?
A type of cell that carries oxygen from the brain to the lungs
A part of the double helix
A notable quality or feature of a person
Most traits are complex as opposed to single.
How does a molecule hold information?
The double helix’s ladder’s rungs are built with the A, C, T, and G DNA alphabet.
It sends it to the ribosomes when it can't hold it anymore.
It stores it in the mRNA
How are genes related to proteins?
Each gene in the DNA encodes information about how to make a specific protein.
Each ribosomes encodes information about how to make a specific protein.
Each nucleotide encodes information about how to make a specific protein.
What is mRNA
They are portable copies of genes. The cell's "flash drive".
3-D “machines, tools, and structures,” printed by ribosomes. The working “apps” of the cell. What is being printed.
The cell's hard drive
The molecular symbols of the genetic code
What do ribosomes do?
Print off proteins
Store all the cell's nucleotides
Create mRNA
All species have the same number of chromosomes.
The number of chromosomes relate directly to the complexity of an organism

Transcriptions
What is the process of transcription?
When mRNA is coded to print protein
Putting DNA genes on mRNA flash drives
When tRNA is sent to the ribosomes
When the ribosomes begin printing proteins
What is the process of translation?
When tRNA is sent out to the ribosomes
When the ribosomes print proteins
When mRNA coded message prints proteins
What are the two functions of DNA?
Printing proteins
mRNA production
Cell replication
Ribosome replication
What is the correct order of the printing process in cells?
-Make an mRNA copy of the gene -Unzip the double helix at the required gene -Send the mRNA copies to the ribosomes -Ribosomes read the mRNA code, print the protein, tRNA brings the amino acids to the ribosomes
-Unzip the double helix at the required gene -Make an mRNA copy of the gene -Send the mRNA copies to the ribosomes -Ribosomes read the mRNA code, print the protein, tRNA brings the amino acids to the ribosomes
-Make an mRNA copy of the gene -Unzip the double helix at the required gene -Send the mRNA copies to the ribosomes -Ribosomes read the mRNA code, print the protein, tRNA brings the amino acids to the ribosomes -Make an mRNA copy of the gene
-Make an mRNA copy of the gene -Send the mRNA copies to the ribosomes -Unzip the double helix at the required gene -Ribosomes read the mRNA code, print the protein, tRNA brings the amino acids to the ribosomes
What is the correct order of the process of DNA replication?
-Proofread the new copies for errors in the nucleotides -Unzip the double helix -Add new nucleotides to each side, creating two new double-helices, each identical to the originals.
-Add new nucleotides to each side, creating two new double-helices, each identical to the originals. -Proofread the new copies for errors in the nucleotides -Unzip the double helix
-Unzip the double helix -Add new nucleotides to each side, creating two new double-helices, each identical to the originals. -Proofread the new copies for errors in the nucleotides
