Classify each description as true of introns only, exons only, or both.A-present in eukaryotic genomesB-generally absent from ba
maxonik [38]

The right answers are:

A-present in eukaryotic genomes ==> Both exons and introns

B-generally absent from bacterial genomes ==> Introns

C-part of the final mRNA strand ==> Exons

D-code for an amino acid sequence ==> Exons

E-removed from initial mRNA strand prior to translation ==> Introns

F-present in the DNA used as the template for transcription ==> Both exons and introns

In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.

Answer:

The whole body works together, as a “team.”If one of the parts of the body won’t work together as a team, everything will get messed up. The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.

Which choice best describes the purpose of most pharmacogenomic research??
zavuch27 [327]
Pharmacogenomic is defined as <span>the study of the role of the </span>genome<span> in </span>drug<span> response. It is a combination of Pharmacology and Genomics.

It studies how the genetic makeup of an individual affects his or her response to drugs. For example, a certain drug is administered to two individuals. One doesn't have any adverse reaction while the other one has. Pharmacogenomics will then conduct tests and study its results on why two individuals given the same drug have different reaction to it.</span>
