The protein-coding strand of the average human gene consists of 1,350 nucleotides. Assuming that each nucleotide can take any of four values (A, T, C, or G), how many different genes with exactly 1,350 nucleotides are possible?

The interphase nucleus appears to be a highly structured organelle with chromosome territories, interchromosomal domains, and transcription factors. In cultured human cells, researchers have identified approximately 8000 transcription factories per cell, each containing an average of eight tightly associated RNAP II molecules actively transcribing RNA. If each RNAP II molecule is transcribing a different gene, how might such a transcription factory appear? Provide a simple diagram that shows eight different genes being transcribed in a transcription factory and includes the promoters, structural genes, and nascent transcripts in your presentation.

The genotype of $\mathrm{F}_1$ individuals in a tetrahybrid cross is AaBbCcDd. Assuming independent assortment of these four genes, what are the probabilities that $\mathrm{F}_2$ offspring will have the following genotypes?

(a) aabbccdd

(b) AaBbCcDd

(c) AABBCCDD

(d) AaBBccDd

(e) AaBBCCdd

A 13-year-old child received an inheritance of $5000 per year. This was to be invested and allowed to accumulate until the child reached 21 years of age. The first payment was made on the child’s 13th birthday and the last on the 21st birthday. If the money was invested at 5.7% compounded annually, what did the child receive at age 21?

A DNA library is a. an orderly array of all the genes within an organism. b. a collection of vectors. c. the collection of plasmids found within a single E. coli. d. a collection of DNA fragments representing the entire genome of an organism.

Genes are sometimes transferred between different species via horizontal gene transfer. Discuss how horizontal gene transfer might give misleading results when constructing a phylogenetic tree. How could you overcome this problem?

You’re probably wearing on your wrist one of the world’s most common types of objects— a watch. Discuss how each of the following terms and concepts applies to the notion of a watch: object, attributes, behaviors, class, inheritance (consider, for example, an alarm clock), abstraction, modeling, messages, encapsulation, interface and information hiding.

With regard to promoting the lytic or lysogenic cycle, what would happen if the following genes were missing from the $\lambda$ genome?
A. cro
B. $c I$
C. $c I I$
D. int
E. $c I I$ and core

Explain how the use of DNA probes with different fluorescence emission wavelengths can be used in a single FISH experiment to map the locations of two or more genes. This method is called chromosome painting. Explain why this is an appropriate term.

a. How many ribosomes are required (at a minimum) for the translation of trpE and trpC from a single transcript of the trp operon? b. How would you expect deletion of the two tryptophan codons in the RNA leader to affect expression of the trpE and trpC genes?

Discuss the following problem. Genes participating in informational processes such as replication, transcription, and translation are transferred between species much less often than are genes involved in metabolism. The basis for this inequality is unclear at present, but one suggestion is that it relates to the underlying complexity of the two types of processes. Informational processes tend to involve large aggregates of different gene products, whereas metabolic reactions are usually catalyzed by enzymes composed of a single protein. Why would the complexity of the underlying process-informational or metabolic-have any effect on the rate of horizontal gene transfer?

In a particular species of butterfly, the genes for two different traits, antenna shape and antenna color, are located on the same chromosome. As a result, crosses between these butterflies do not obey one of Mendel's laws. Which law does not apply, and why?

It is known by researchers that 1 in 100 people carries a gene that leads to the inheritance of a certain chronic disease. In a random sample of 1000 individuals, what is the probability that fewer than 7 individuals carry the gene? Use a Poisson approximation. Again, using the approximation, what is the approximate mean number of people out of 1000 carrying the gene?
