Chromosome 3 contains nearly 200 million nucleotide pairs of our genome. If this DNA molecule could be laid end to end, how long would it be? The distance between neighboring base pairs in DNA is typically around 0.34 nm.
About 7 mm
About 7 cm
About 7 m
None of the above
Homework Answers
The answer is 7.4 cm.
200 million is 2.0 x 10^8. Multiply this by 0.34 nm = 7.4 x 10^7 nm. 1 nanometre is 1.0 x 10^-9 m, so 7.4 x 10^7 nm is 0.074 m or 7.4 cm.

Our understanding of RNA
was non-existent until 2000
started with the identification of a tRNA which suggested a
method of converting DNA to protein
began to identify that DNA-->protein--> RNA
stopped growing after it's original discovery in the 70s

3. (22 points) Researchers sampled mitochondrial DNA from populations of two species of insect herbivores throughout their range, which includes the North American mainland and the peninsula of Baja California, a map of the sampled populations is shown in Figure 2. They calculated haplotype diversity and counted number of haplotypes for each species (Table 3), performed an AMOVA (Table 4), and determined pairwise Fst values between populations, illustrated by the matrices in Tables 5 and 6. Based on these data,...

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
