Question

1) Which of the following is true about prokaryotic genomes a) prokaryotic genomes are less complex than eukaryotic genomes b) prokaryotic genomes havé many repetative sequences d) none of the above 2) Orthologs a) homologous genes in the same cell b) homologous genes in different organisms c) non-homologous genes d) none of the above 3) Which nucleic acid is subject to altenative splicing a) DNA b) mRNA c) TRNA d) none of the above 4) Evolution is based on a) variation with a species b) natural selection c) both d) neither 5) Homologous structures a) are structures that are not evolutionarily related but have the same b) are structures that are evolutionarily related but have different fumctions. c) are structures that are found in the same species d) none of the above 6) In the Hardy-Weinberg equation q4 is a) the frequency of heterozygotes b) the frequency of homozygous dominant individuals d) none of the above

Explanation / Answer

1.a....prokaryotic genome is contained in a single circular DNA molecule. As well as this single 'chromosome'

2.b...Orthologs are genes in different species that evolved from a common ancestral gene by speciation.(ortholog is a sub category of homologous)

3.b....exons in a pre-mRNA transcript is an important mechanism which contributes to protein diversity in human. Alternative splicing produces mRNA.

4.c...both

5.b....Even though bone structure may be very similar, function varies widely. Homologous limbs can be used for flying, swimming, walking, or everything humans do with their arms. These functions evolved through natural selection over millions of years.

6.c...In the equation, p2 represents the frequency of the homozygous genotype AA, q2 represents the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa.
