Total questions: 20
Worksheet time: 11mins
Which organelle is the location where protein is made?
Ribosome
Nucleus
Cytoplasm
Nucleotide
During transcription, this type of ribonucleic acid is responsible for copying the DNA and brining it out of the nucleus.
tRNA
mRNA
rRNA
dRNA
When these bond together, they form a protein
Amino Acids
Peptide Bonds
Ribose
Nucleotides
These building blocks consist of a sugar, phosphate, and nitrogen base.
Ribose
Nucleotide
Gene
Protein
A string of nucleotides that contain the information to make a specific protein
Ribose
Amino Acids
tRNA
Gene
mRNA is created during this process
Translation
Transcription
Replication
Delivery
One human disease is caused by a change in the bases of a gene from GAA to GTA. The disease is a result of
a mutation
crossing-over
a meiosis error
polyploidy
Which component of DNA determines the traits of an organism?
Nitrogen Bases
Sugar-Phosphate Backbone
Hydrogen bonds
Deoxyribose
What is the location in the cell for translation?
nucleus
mitochondria in cytoplasm
ribosome in cytoplasm
chloroplast in cytoplasm
Which of the following provides the best description of the function of chromosomes?
Ridding individual cells of waste products
Relaying information from the environment
Producing energy through cellular respiration
Controlling the production of specific proteins
The transfer of genetic info from DNA to RNA is called
translation
transcription
initiation
elongation
A gene is
the same as a chromosome
the info for making a polypeptide
made of RNA
made of protein
Why does a human body need proteins?
To place amino acids in a specific order
To guard against harmful mutations
To send messages to the cell's cytoplasm
To perform important bodily functions
Some scientists claim that the gene that controls the production of hemoglobin, a protein responsible for the binding of oxygen to red blood cells in humans, is located at the position shown in the diagram.
Which of the following observations would provide the best evidence for this claim?
Humans lacking this gene exhibit problems with oxygen binding in their red blood cells.
Other organisms that require oxygen have similar genes in similar locations.
Nearby genes on the chromosome are thought to control other blood factors.
Healthy humans all have this same gene in exactly the same location.
