Liam lives with his family. A valuable vase was stolen from his house, and Liam's DNA fingerprint was on the vase when it was found. Based solely on this evidence, would you convict Liam of theft of his own vase?
Yes, because his DNA fingerprint is on the vase.
No, because Liam could have placed spread his DNA to the vase as he dusted it
To keep from cross-contaminating a DNA sample, for each sample, you should:
Use the same pipette for each sample
Use different, sterile pipettes for each sample
Take no more than two samples with each pipette
How might genetic engineers help make food more nutritious?
Vitamin A and iodine added to rice
Vitamin A added to sweet potatoes
Iron added to make lettuce more nutritious
All choices are correct
What are some of the ways that foods can be genetically modified to help meet the demands of a growing population?
Salt-tolerant crops and drought-tolerant crops
Broad-range-temperature tolerant crops
Higher-yielding crops
All choices are correct
Wild foxes are aggressive and unfriendly toward humans. However, Russian scientists have worked since the 1950s to breed a domesticated version of the silver fox. Each year, the scientists choose the tamest foxes to mate together. Gradually, the foxes are becoming more like dogs. They are much more friendly and playful than wild foxes. What technique is used to increase desirable traits in domesticated animals through breeding?
Natural selection
Genome selection
Cloning selection
Artificial selection
Zika fever is a viral disease. The virus is transmitted by Aedes aegypti mosquito bites. Most people have only mild symptoms from Zika. However, Zika can cause pregnant woman to have babies with serious birth defects. A British company is working to reduce mosquito populations through genetic engineering. The company has genetically modified A. Aegypti mosquitoes so their offspring die before they mature. Tests in Brazil showed that local A. Aegypti populations dropped 80-90% after the genetically modified mosquitoes were released. Which of the following statements is true of all genetically engineered organisms?
They have a genome that is identical to their parents’ genome.
They are made using half the genomes of two different species.
They contain genes transferred from another organism.
They are produced by breeding only the individuals with desired traits.
Tay-Sachs disease is a recessive genetic condition that damages the brain and causes early death. Miriam had an uncle who died of the disease at age 2. Miriam is considering having a child. She wants to have her DNA tested for the Tay-Sachs gene. How can genome sequencing help Miriam decide whether to have a child?
Genome sequencing will tell Miriam whether she is a carrier of the Tay-Sachs gene.
Genome sequencing will tell Miriam that her children will have Tay-Sachs disease.
Genome sequencing will allow Miriam’s children to get gene therapy for Tay-Sachs disease.
Genome sequencing will tell Miriam how closely-related she will be to her children.
Shortly after World War II, chickens were bred to grow much more quickly and produce more meat. What is this an example of?
Cloning
Artificial selection
Genome sequencing
Natural selection
Selective breeding is also known as:
Cloning
Artificial selection
Genome sequencing
Natural selection
Through what process can scientists transfer a gene from the DNA of one organism into another?
Genome sequencing
Natural selection
Natural breeding
Genetic engineering
