Section 3 Flashcards
(25 cards)
Scientists test for alleles that cause human genetic disorders by
detecting the DNA sequences found in those alleles.
*
The process of DNA fingerprinting is based on the fact that
no two people, except identical twins, have exactly the same DNA.
What conclusion CANNOT be made from two DNA fingerprints that show identical patterns of bands?
The DNA from the two DNA fingerprints definitely came from two different people.
The Human Genome Project is an attempt to
sequence all human DNA.
The human genome was sequenced
by looking for overlapping regions between sequenced DNA fragments.
Which of the following information CANNOT be obtained from the Human Genome Project?
Which of the following information CANNOT be obtained from the Human Genome Project?
*
The purpose of gene therapy is to
cure genetic disorders.
*
Which of the following is the first step in gene therapy?
identifying the faulty gene that causes the disease
*
Gene therapy is successful if the
replacement gene is replicated in the person’s cells.
Which of these is an example of the benefits of genetic engineering?
creating human insulin to treat people with diabetes
The Human Genome Project can help genetic engineers produce human proteins because
to produce a protein, geneticists must know the sequence of DNA bases that codes for the protein.
What is the purpose of the Human Genome Project?
to identify the DNA sequence of every gene in the human genome
What is a genome?
all the DNA in one cell of an organism
Except for identical twins, all people have the same DNA. _________________________
False different
The goal of DNA fingerprinting is to identify the DNA sequence of every gene. _________________________
the human genome project
A person can be tested for the allele that causes Huntington’s disease because the _________________________ of that allele is different from that of the normal allele.
DNA sequence
In DNA fingerprinting, the DNA probe that is used is ____________________ to the DNA sequence of the repeats.
Unknown
The three alleles on the single gene that controls blood type are said to be ____________________ alleles.
polygenetic
The process of _________________________ replaces a faulty gene with a normal working gene.
gene therapy
Scientists in the Human Genome Project are working to identify the ____________________ sequence of every human gene.
DNA
All of the DNA in one cell of an organism is called a(n) ____________________.
genome
A pattern produced from fragments of the DNA of a specific person is called a(n) ____________________.
DNA fingerprint
DNA fingerprinting analyzes sections of DNA that have little or no known function but are similar from person to person.
True
To locate genes within the human DNA sequence, scientists look for open reading frames within the sequence.
True
