Discuss Genome characteristics – explain how genome size and gene density differ in simple organisms, such as prokaryotes, versus more complex organisms, such as ourselves. Discuss why these different genome characteristics exist in simple versus complex organisms.

Once an organism's genome sequence has been determined, which of the following methods is not used to identify all the genes within the genome? Question options: a). Search for DNA sequences of genes known from other organisms b. Individually mutate nucleotides and determine which mutations cause a detectable phenotype c. Sequence cDNAs from different tissues and/or conditions and match them to the genome sequence. d. Look for open reading frames by searching for stretches of DNA sequence without stop codons....

A cell's genome is its blueprint for life. However, what is the bare minimum number of genes needed to sustain a free-living cell? This is a question that microbiologists at the J. Craig Venter Institute (JCVI) have attempted to answer ever since they sequenced the genomes of several Mycoplasma species in the 1990s. Because Mycoplasma species are parasitic bacteria, their genomes are already reduced in size and hence provide an excellent foundation for creating a "minimal cell." However, little did...

To estimate the genome size of a newly discovered organism, you digest one copy of its genomic DNA with the restriction enzyme EcoRI, which has a 6 bp recognition site. The genome is cut into about 100,000 fragments. Which is your best estimate of the size of this organism’s genome?

2) The cowpea chlorotic mottle virus is one of the simplest organisms known. It consists of just two things: an RNA genome, and an approximately spherical shell that holds and protects the genome (the shell is called a capsid). The capsid consists of 180 copies of the same protein molecule. If you prepare a solution containing the protein molecules and the RNA genome, these will, under the right buffer conditions, spontaneously self-assemble into intact, infectious viruses. Consider the following statement:...
