1 This term describes the shape of DNA. What is ….A DOUBLE HELIX Click here for answer back

2 These are the small, repeating units that DNA is composed of. back Click here for answer What are ….NUCLEOTIDES.

3 This is the sugar that is found in DNA. back Click here for answer What is ….DEOXYRIBOSE.

4 These are the types of bonds that are found between complementary base pairs. back Click here for answer What are ….HYDROGEN BONDS.

1 DNA replication occurs during this phase of the cell cycle. back Click here for answer What is ….S PHASE.

2 This enzyme unwinds twisted strands of DNA. back Click here for answer What is …. HELICASE.

3 Because newly synthesized DNA contains one parent strand and one new strand, replication is said to be this. back Click here for answer What is …. SEMI-CONSERVATIVE

4 This is the enzyme that adds DNA nucleotides during replication. back Click here for answer What is….DNA Polymerase

1 back Click here for answer What are….SOMATIC CELLS Mutations can occur in sex cells, or in this type of cell.

2 back Click here for answer What are ….GAMETES Mutations that occur in these type of cells will be passed on to future generations.

3 back Click here for answer What is …. NON-DISJUNCTION. When homologous chromosomes fail to separate properly during anaphase 1 of meiosis, it is referred to as this.

4 back Click here for answer What is ….TRANSLOCATION. When one part of a non-homologous chromosome breaks off and attaches to another chromosome it s referred to as this type of mutation.

1 This is the full name of RNA. back Click here for answer What is….RIBONUCLEIC ACID

2 RNA contains this base instead of Thymine. back Click here for answer What is….URACIL.

3 This is the sugar that is found in RNA. back Click here for answer What is ….RIBOSE.

4 There are this many types of RNA. back Click here for answer What is ….THREE

1 back Click here for answer What is ….TRISOMY 21. Downs Syndrome is also known as this, because of its 3 copies of chromosome 21.

2 back Click here for answer What is ….KLINEFELTERS This disorder is found in males who have the genotype XXY.

3 back Click here for answer What is….X__ Females who have Turners Syndrome have this as their genotype.

4 back Click here for answer What is ….MONOSOMY Non-disjunction can result in a trisomy or this chromosome abnormality.

FINAL JEOPARDY CATEGORY: Mutations and Disorders

This genetic disorder is caused by an extra copy of chromosome 18, and has the following characteristics: 1/3000 births Mental Retardation Failure to thrive Heart defect Overlapping fingers Low set, fawn-like ears

Answer… What is… EDWARDS SYNDROME
