Question

dna does all but which of the following?
○ is read by ribosomes during the process of translation
○ serves as the genetic material passed from parent to offspring
○ remains constant despite changes in environmental conditions
○ provides the instructions for the synthesis of messenger rna
question 14 (1 point)
bacteria that grow in mine drainage at ph 1-2 are probably which of the following?
○ alkaliphiles
○ neutrophiles
○ obligate anaerobes
○ acidophiles

Explanation:

First Question (DNA function)

To solve this, we analyze each option:

• "is read by ribosomes during translation": Ribosomes read mRNA, not DNA, during translation. DNA is transcribed to mRNA first.
• "serves as genetic material passed to offspring": DNA is the hereditary material, so this is a function of DNA.
• "remains constant despite environmental changes": DNA is stable and its sequence (mostly) doesn’t change with environment (mutations are rare exceptions, but the option is about its role, and it’s stable as genetic material).
• "provides instructions for mRNA synthesis": DNA is transcribed into mRNA, so this is a function (transcription).

So the incorrect one (what DNA does NOT do) is the first option.

We analyze each term:

• alkaliphiles: Grow in alkaline (high pH) conditions, not acidic (pH 1 - 2 is very acidic).
• neutrophiles: Grow in neutral pH (around 7), not pH 1 - 2.
• obligate anaerobes: Relate to oxygen tolerance, not pH.
• acidophiles: Organisms that grow in acidic environments (low pH, like pH 1 - 2). Mine drainage with pH 1 - 2 is acidic, so acidophiles fit.

Answer:

is read by ribosomes during the process of translation
