Researchers are investigating the use of gene therapy as a treatment option for human genetic disorders, such as cystic fibrosis. When gene therapy is successful, how does it treat the disorder?
A. by activating, or "turning on," one or more genes
B. by deactivating, or "turning off," one or more genes
C. by incorporating a human gene into the genomes of bacteria or other organisms
D. by replacing a faulty gene with a normal gene in the human genome
Answers
Answer:
A
Explanation:
By replacing a faulty gene with a normal gene in the human genome. Therefore, option (D) is correct.
Gene therapy works by inserting a functioning gene into a patient's cells. A viral vector or other delivery method transports the normal gene into target cells.
In cells, the normal gene integrates into the genome and produces the functional protein that was missing or faulty in genetic disorder patients. Gene therapy replaces the damaged gene with a normal gene to repair the genetic origin of the condition and restore normal cell or tissue function.

Briefly explain the three clues that suggest that bacteria are an evolutionary success story
Answers
Answer:
The evolutionary success of this group results from its 1- small size, 2- simplicity and 3- fast reproduction rate
Explanation:
Bacteria are evolutionarily successful organisms that makeup about 15 percent of all biomass on Earth, and they occupy almost all habitats in nature. The small size of these unicellular organisms facilitates the exchange of nutrients and waste products with the surrounding environment. In addition, the relative simplicity of bacteria also facilitates the assembly of cell structures as well as a fast reproduction rate by the fast division of single cells. All these features are critical in order to understand the rapid evolution rate observed in this group.

If the DNA is: TAC CGA CCG ACC TTA. Create a mRNA strand with a point mutation that would “not affect” the protein.
Answers
Answer:
AUG GCU GGG AGG AAU
Explanation:
A point mutation that would not affect the protein is one that has the same mRNA codon. The answer choices indicate that the third part is affected. The normal mRNA would be GGC, which if you look at the table, is gly. The other sequences that match are GGU, GGC, GGA, and GGG. The only answer choice that matches is the third one, with GGG.

Answers
In this activity, students learn about the Human Genome Project. They do an interactive Web activity which simulates the process scientists use to determine the sequence of chromosomal DNA bases. Then they learn how two teams of scientists raced to decode the human genome. Next they explore a stretch of sequenced DNA on the Web to learn about the function of different sections of DNA code. They learn how knowledge of the human genome is being applied to medicine. They also learn about genetic variation among humans and between humans and other species. Finally, they assess what they have learned about the Human Genome Project by playing a game of Jeopardy.
Objectives
Learn about the purpose and work of the Human Genome Project
Describe the process of sequencing human DNA
Understand the functions of different stretches of code on a chromosome
Recognize the similarity in the genetic code among humans and between humans and other species
Learn how the Human Genome Project can contribute to curing diseases

Why does the DNA have to be cut into pieces? How is this done?
How are DNA copies made in the lab?
How do primers and special fluorescent nucleotides help determine the DNA sequences?

What does the majority of the DNA in chromosomes code for?
What is the role of gene promoters like TATA boxes?
How does the "machinery" of the cell know where to begin reading the gene?
What are exons, and what is their function in the chromosomes?
What are introns, and what do they do? What happens to them when DNA is transcribed into mRNA?
What are the roles of "hitchhiking" and ancient code in human DNA, and where did they come from?
How alike is the DNA from two different humans?
What is a gene, and what role do genes play in the human body?
5. Show the video HIV Immunity to examine some of the benefits of mapping the human genome. Ask:
What are outliers, and what is their value in understanding disease?
How can a genetic mutation be advantageous?
How is the knowledge of mutations being used to combat the HIV virus?
6. Show the video Genetic Variation and discuss the following:
Whose genes are being sequenced in the two human genome projects?
Are these genes representative of the human species? Why or why not?
What is the percentage of genetic difference between any two humans?
What does the similarity of basic functions between different organisms indicate?
7. Finally, have students read the Genome Facts document. Have students use these facts and what they have learned about the Human Genome Project to create a series of answers and questions for a Jeopardy quiz show. (

Answer:
i believe it's A, C and D but I could be wrong
Explanation:
The changes that are likely to occur include. There will be an increase in the number of figs being eaten by coatis, an increase in the beetle population, and the number of figs eaten by fruit bats. Thus the options B, C, and E are correct.
What is poisonous dark forg?The poisons dart frog is an amphibian species that is known to live in central and south America, the species are brightly colored and have a poision on their skin glands.
The brighter the frog more is the toxicity. The death of the poison dart frogs will lead to an increase in the population of fruit bats and figs being eaten by coatis. The beetle population will also grow. As the fungus will grow in large numbers.
