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

Answer:

D. After a gene is transcribed, introns are removed from the pre-mRNA to form the mRNA that is translated.

Explanation:

The statement that provides the strongest evidence against the validity of Brendan's claim is that after a gene is transcribed, introns are removed from the pre-mRNA to form a mRNA that is then translated.

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.

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.

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.

The correct option is D.

What are the benefits to the host of diplomonads?

7nadin3 [17]

Answer: C) the parasite benefits, and the host is harmed; however, the host is not generally killed.

Killing the host would be bad for the parasite, as it would have no place to live.

Explain how you could determine wheater seeds in packets of round pea seeds have a genotype rr or rr

mezya [45]

I think you mean Round could be RR or Rr (round is dominant to wrinkled)
R=round
r=wrinkled
RR would be round phenotypically
Rr would be round phenotypically
To determine if they are RR or Rr you should perform a backcross with a wrinkled mutant!
I put a picture to demonstrate this.
If they are RR then if you cross with rr you would only get phenotypically Round pea plants.
If they are Rr then if you cross with rr you would get 50% round and 50% wrinkled. Any wrinkled? Definitely the heterozygote Rr!!
