Answer:
D. After a gene is transcribed, introns are removed from the pre-mRNA to form the mRNA that is translated.
Explanation:
<em>The statement that provides the strongest evidence against the validity of Brendan's claim is that </em><em>after a gene is transcribed, introns are removed from the pre-mRNA to form a mRNA that is then translated.</em>
<u>A newly transcribed gene usually have two group of nucleotides - the exons and the introns. Exons are otherwise known as he coding sequence of a gene while introns are known as the non-coding sequence of a gene.</u>
After transcription, the introns are excised out of the nucleotide sequence of the newly produced mRNA. The remaining nucleotides are then spliced before they are transported to the cytoplasm to be translated into proteins.
<em>Hence, the sequence of amino acids in a protein that will be formed by a pre-mRNA cannot be determined until the non-coding sequence are removed.</em>
The correct option is D.
Answer:
The correct answer is : prokaryotic organisms like E. coli and higher organisms share common ancestor.
Explanation:
E. Coli is a prokaryotic organism or bacteria. On the metabolic level these organisms share similar homology with the higher organism other than this these organisms also show same core functions with higher level organisms such as elephant.
These similarities suggest that the all the living organisms share a common ancestor. The french scientist Jacques Monod statement "Anything found to be true of E. Coli must also be true of elephants." is also based on this notion.
The answer is B.
