Question

your biology teacher assigns you dna as your informative speech topic.
which type of informative speech would you choose to deliver information about dna? explain why you would choose this type of speech.
which type of organization style would you use for your speech and why?

Explanation:

For the first part, an informative speech about DNA could be a speech about an object (as DNA is a biological object). DNA has a physical structure (double - helix) and functions (genetic information storage, replication, transcription). This type of speech allows for describing its components (nucleotides, base - pairing), structure (how the double - helix is formed), and function (how it codes for proteins).

For the organization style, a spatial organization style could be used. Since DNA has a physical structure (the double - helix), starting from the basic building blocks (nucleotides) and moving up to the overall structure (the double - helix shape) and then to how it is organized in cells (chromosomes) follows a spatial - like progression. Another option could be a cause - effect organization if discussing how DNA mutations (cause) lead to genetic disorders (effect), but spatial is more directly related to its physical nature.

Answer:

• Type of informative speech: Speech about an object. DNA is a biological object with a defined structure (double - helix made of nucleotides) and function (stores and transmits genetic information). This type of speech can cover its physical components, structure, and role in living organisms.
• Organization style: Spatial organization. DNA has a physical structure (from nucleotides to the double - helix to its packaging in chromosomes). A spatial organization can start from the smallest unit (nucleotide), move to the secondary structure (double - helix), and then to its organization within cells (chromosomes in the nucleus), making it logical for explaining its physical nature.
