Endospores
A) are bacterial reproductive structures. B) can be produced when nutrients are scarce. C) are produced by bacteria, algae, and fungi. D) are resistant to everything except radiation. E) can last for only about 100 years.
In some mammalian tissues, the mRNAs for proteins such as apolipoprotein-B and glutamate receptors are edited before translation to alter the information encoded in the original genes
What enzymes are responsible for this editing, and what do they do? What will be an ideal response?
In rabbits, spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b). A true-breeding black spotted rabbit is mated to a true-breeding brown solid rabbit to produce a heterozygous F1 generation. Two F1 individuals are mated, and you do not see a 9:3:3:1 (black spotted: black solid: brown spotted: brown solid) ratio of offspring, but instead see that almost all offspring are a non-recombinant phenotype. This tells you that
A. that the genes for fur pattern (spotted vs. nonspotted) and fur color are on the same chromosome. B. that the genes for fur pattern (spotted vs. nonspotted) and fur color assort independently. C. that fur pattern (spotted vs. nonspotted) and fur color are maternally inherited. D. that the genes for fur pattern (spotted vs. nonspotted) and fur color are on the X-chromosome and Y-chromosome, respectively. E. that the genes for fur pattern (spotted vs. nonspotted) and fur color are on different chromosomes.
