Translation of the DNA sequence AAGCTGGGA would result inA)an mRNA strand with the sequence TTCGACCCT.
vaieri [72.5K]

Answer:

D. A Sequence of three amino acids linked by peptide bonds.

Explanation:

Well, it cannot be A or C because those answers contain the letter T, otherwise, know as Thymine. Thymine is only found in DNA sequences, not it RNA. RNA sequences replace Thymine with Uracil, which brings me to the next point. It can't be answer choice B. because it contains an error in translation. The 3rd and 4th letter in, CG should translate to GC in the RNA strand, but it doesn't. This is why your answer is D.

Hope I helped!

These photosynthetic protists produce one third of the Earth’s oxygen that is generated through photosynthesis.
STALIN [3.7K]
<h2>Answer:  C) Algae</h2>

Explanation:

By process of elimination:

  • moss is a plant belonging to the Bryophyta division. It is not a protist
  • paramecia are animal-like protists that don't generally photosynthesize
  • protozoans feed on organic matter such as other microorganisms or organic tissues and debris (not autotrophic)
  • This leaves Algae, which are autotrophic protists.
