<span>Modern humans have been around for a very short period of time. There are differences in race, asian people tend to be smaller, stuff like that. The problem is different races marry and those genes mix. If Asians only married pure blood Asians, Africans only married and procreated with other Africans thanks in hundreds of thousands of years different sub species would most likely start to occur. Seeing as how human population is all connected today, that won't happen.</span>

A scientist has sequenced a gene from a multicellular eukaryotic organism. Brendan claims that by analyzing the gene sequence an
Bas_tet [7]

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.

daser333 [38]

Answer:

The promoter

Explanation:

The promoter region is the region of DNA sequence which the RNA polymer binds to to initiate transcription. In the archae and eukaryotes, the core portion of the promoter region is called the TATA BOX. The promoter region is also located upstream of the DNA and can about a 100-1000 base pairs long.
