BJU Press Life Science 4th Edition Chapter 7 Review

Most mutations help an organism survive in a new environment.

Use of somatic stem cells does not require killing of human embryos.

Somatic mutations are generally less important than germ mutations.

The Human Genome Project identified the genes that code for every trait in the human body.

All mutations have a noticeable, harmful effect in an organism.

Mutations add new information to DNA.

A change to the sequence of bases in the segment of DNA that makes up a gene is called:

Many mutations are harmful to organisms.

A change in the number of chromosomes or the number or location of genes on a chromosome is called:

A gene mutation causes a change in the number of chromosomes that an organism has.

Which is not true of identical and fraternal twins?

Stem cells that come from differentiated body cells are:

A mutation that results in the death of the organism is called:

Therapeutic cloning produces clones for medical research.

Clones are produced by:

What type of mutation can affect an organism’s offspring?

The process of a cell becoming specialized is called differentiation.

Natural clones are very rare.

Breeding an animal with its close relatives is called:

Using special techniques to control the genetic makeup of an organism is called genetic engineering.

The human Genome Project mapped the DNA nucleotide sequence in the human genome.

The genome is pretty stable.

A mutation in a sweat-producing cell that causes the cell to not be able to produce sweat is a:

Fraternal twins are not clones.

Scientists have genetically engineered bacteria to produce human insulin. Why can humans use it?

What are two major changes God has caused in the world since creation?

Which of these would be the most affected by a lethal somatic mutation?

The Bible forbids genetic engineering.

Albinism is a mutation that does not cause harm to the organism.

Which of these conditions is the result of a chromosomal change?

A farmer decides to breed two different types of corn to produce a new variety with desirable traits.

Breeding organisms from different varieties is called crossbreeding.

Gene therapy is used to help treat certain diseases by correcting defective genes.

Which is an example of a germ mutation.

Which of the following would be most likely to cause a chromosomal change?

A mutation is any change in an organism’s genetic material.

Shorter human lifespans, diseases, and genetic disorders are examples of:

What genetic disease is infamous for affecting European royalty?

Some forms of cotton have four sets of chromosomes instead of two.

Which of these do you know is a germ mutation?

Mutations are examples of degeneration.

Reproductive cloning is producing human clones for people who are unable to have children naturally.

Which of these is not an example of a clone?

The use of living organisms to create a new, more desirable organism or product is called:

Choosing organisms with desirable traits and breeding them is called:

Which affects more genes, gene mutation or chromosomal change?

Natural clones only exist in the plant kingdom.

Embryonic stem cells are already being used to treat over 70 different diseases.

Which type of stem cell research is wrong.

Therapeutic cloning is scripturally acceptable because it can provide organs for people who need transplants.

Fraternal twins have identical genes.

Down syndrome is caused by three copies of chromosome 21. This is an example of chromosomal change.

Which of these would not be an example of biotechnology:

Somatic Mutations occur in body cells, cells that do not produce sperm and eggs.

Special enzymes “proofread” and repair mistakes in the DNA.

Which of the following is not a potential advantage of developing cloned organisms?

A somatic mutation are mutations that occur in gametes or in the cells that make gametes (sperm and eggs)
