In DNA replication, DNA polymerase catalyzes the reaction in which

the double helix unwinds

the sugar-phosphate bonds of each strand are broken

a phosphate group is added to the 3’-carbon or 5’-carbon of ribose

a nucleotide with a base complimentary to the base on the template strand is added to the new DNA strand

the two nucleotide strands come together and intertwine to form a double helix

All of the following are true statements about meiosis in mammals EXCEPT:

It serves as a factor in bringing about variation among offspring

It follows DNA replication

It occurs only in reproductive structures

It produces cells with the haploid number of chromosomes

It produces four genetically identical gametes

Analysis of DNA sequences from two individuals of the same species results in greater estimate of genetic variability than does analysis of amino acid sequences from the same individuals because

different DNA sequences can code for the same amino acid

some amino acid variations cannot be detected by protein electrophoresis

DNA sequencing is a more reliable technique than protein electrophoresis

proteins are more easily damaged than is DNA

DNA is more heat-sensitive and therefore varies more

1,400,P

During development, individual cells of the same organism begin to produce different proteins because

the cells have different numbers of chromosomes

not all cells can synthesize proteins

specific genes are activated in the cells

the cells have different kinds and amounts of DNA

genes are permanently lost as somatic cells differentiate

Actinomycin D is an antibiotic drug that inhibits protein synthesis by blocking transcription. In some cells, the application of the drug does NOT affect the synthesis of certain proteins. Which of the following best explains such an occurrence?

Not all proteins need tRNA molecules for their synthesis.

Some proteins that are made are using mRNA synthesized before application of the drug.

Nuclear proteins do not require the cytoplasmic machinery of ribosomes.

DNA transcription is not necessary for protein synthesis.

Protein synthesis is blocked in the cytoplasm at the ribosome level.

A child is born with blood type A to a mother with blood type B. If the father has blood type AB, which of the following statements is correct about the mother? (where IA = A, IB = B, i = O)

She contributes an IB allele, which is recessive to the father’s IA allele.

She contributes an i allele, which is recessive to the father’s IA allele.

She contributes an IB allele, which is codominant to the father’s IA allele.

She contributes an i allele, which is codominant to the father’s IB allele.

She is homozygous for the IB allele.

In peas the trait for tall plants is dominant (T) and the trait for short plants is recessive (t). The trait for yellow seed color is dominant (Y) and the trait for green seed color is recessive (y).

A form of vitamin D-resistant rickets, known as hypophosphatemia, is inherited as an X-linked dominant trait. If a male with hypophosphatemia marries a normal female, which of the following predictions concerning their potential progeny would be true?

Achondroplastic dwarfism is a dominant genetic trait that causes severe malformation of the skeleton. Homozygotes for this condition are spontaneously aborted (hence, the homozygous condition is lethal) but heterozygotes will develop to be dwarfed.Matthew has a family history of the condition, although he does not express the trait. Jane is an achondroplastic dwarf. Matthew and Jane are planning a family of several children and want to know the chances of producing a child with achondroplastic dwarfism.

If three children are born to Matthew and Jane, what are the chances that the first two children will not express the trait but that the third child will be an achondroplastic dwarf?
