I would say B.
A, umm, don't crash trains, that's bad.
C, Lillian is wondering how fast a train can go, not at what curve will it fall.
D, Lillian isn't wondering about the size of the trains, just the speed.
Answer:
The exons may be defined as the coding region of the RNA that codes for the particular amino acid. The introns are the non coding region of RNA and must be removed in the final RNA product.
Exon shuffling result in the formation of new gene. The alteration of the exon and intron structure leads to the new gene function in evolution. The genes that are favored and conserved in the evolution perform new gene function. The genes that are selected against are deleted during the evolution.
Answer:
You tell her that this is incorrect.
Explanation:
The given information is incorrect as both small and large ribosomal subunits are required for protein synthesis. The eukaryotic ribosomes have E, P, and A sites. The A and P sites bind to the aminoacyl tRNA that carry the amino acid encoded by the codon of the mRNA.
The formation of peptide bond occurs between the amino group of amino acid in A site and the carboxyl group of amino acid present on P site. Both 40S and 60S subunit of ribosome contribute the A and P sites.
The original question has a set of choices. This is within the context of cell division. The choices are:
A. A cell in G1 of interphase and a cell in G2 of interphase
B. A cell in G1 of interphase and a cell immediately after the completion of meiosis II
C. A cell in G1 of interphase and a cell in metaphase II of meiosis
D. A cell in G2 of interphase and a cell in metaphase II of meiosis
<span>E. None of the above.
</span>
The correct answer is C. A cell in G1 is diploid and the cell in meiosis II is haploid but the amount of DNA still equivalent as each chromosome in the haploid cell consists of two chromatids. G2 cells already had been through the S phase therefore the genetic material is already doubled. A cell immediately after meiosis II has half the genetic material.
