The base composition of an rna virus was analyzed and found to be 14.1% a, 14.0% u, 36.2% g, and 35.7% c. would you conclude that the viral genetic material is single-stranded rna or double-stranded rna? 2. the genetic material found within some viruses is single-stranded dna. would this genetic material contain equal amounts of a and t and equal amounts of g and c?

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).

Genes that come together with different alleles are heterozygous. homozygous. genotype. segregated.
