The transmission of genetic material from one generation to the next is necessary for the survival of a species. which statement describes one property that to ensure the reliable transmission of genetic information in living organisms? question 4 options: a) rna uses a nucleotide base called uracil to distinguish itself from dna. b) a pyrimidine base will only pair with the correct purine base. c) the two strands of a dna molecule cannot be separated. d) translation of mrna to assemble a protein is a reversible process.

How is ribosomal rna useful as a molecular clock? a. a large portion of the dna ring is not vital to structure or function, allowing it to accumulate neutral mutations. b. its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. c. a slow mutation rate makes it useful for determining evolutionary relationships between ancient species. d. it is only found in select organisms, making it easier to compare relationships between species that have it.

Which statement best describes a typical difference that could be found between the "analysis" and "conclusion" sections of a lab report? a) only the "conclusion" describes errors that occurred during the experiment, and only the "analysis" section suggests further research.b) only the "analysis" section includes specific data comparisons, and only the "conclusion" section suggests further research.c) only the "analysis" section discusses whether the original hypothesis was supported, and both sections include graphs of data.d) only the "conclusion section discusses whether the original hypothesis was supported, and both sections suggest further research.(the answer is b i just took the test)

Which best describes a gene? a. a sister chromatid b. a chromosome c. a tetrad d. a piece of a chromosome
