The correct answer is: b. the removal of introns and alternative splicing of exons
Post-transcriptional regulation includes processes of regulation between transcription and translation such as RNA splicing, capping, addition of poly-A tail, RNA editing.
RNA splicing represents the process of RNA processing in which newly synthesized pre-mRNA transcript is converted into a mature mRNA. This process occurs only in eukaryotic organism and includes the removal of introns and joining together the exons. RNA splicing might occur during or immediately after transcription and it is performed by spliceosome (complex of small nuclear ribonucleo proteins).
Alternative splicing is a regulated process in which a single gene can code for multiple proteins because particular exons of a gene may be included within or excluded from the final mRNA.

Dear Sarah.
Firstly, I am very happy to know that you have decided to start a study schedule for your literature course in Colonial Latin America, I believe that you will gain great knowledge and that this will be very important for your academic career.
Because of the importance of this study, I decided to analyze your study methods and I fear that they are not efficient and that you will lose time and do not absorb the concepts really necessary for you.
Your study method is based on memorizing concepts and quotes and I believe that you should not rely on it to study, as our memory is relative and often does not last as long as necessary. So I decided to give you advice that I used during my study and that were extremely efficient.
My first advice is that you divide all the material that you have to study in small modules and establish an expert for the study of each one. Don't forget to put a rest time so that you don't get overwhelmed and start taking your readings automatically.
My second advice is that when you study each module, write summaries with the main parts and make mind maps that will be extremely necessary to make revisions.
My last and most important advice is that you make constant reviews and try to conceptualize and reason during this process, this will prevent you from memorizing, but introducing the concepts in your mind in order to understand them and not record them.
I am grateful that you will be successful if you follow these steps and I expect answers from you telling me the results.
Affectionately,
Caroline.
Answer:
GENE
Explanation:
The functional segment of the DNA that contain instructions for a specific trait is known as a gene.
Answer:
d. All of the above exemplify the difference between a population and an individual.
Explanation:
A population is a group of individuals of the same species that live in a particular geographical area and are able to interbreed. A population is described with respect to several features such as death and birth rates, age structure, density, dispersion, change in the population size due to density-dependent and density-independent factors and the survivorship curve.
These features are not exhibited by a particular individual. Natural selection also works at populations. The evolutionary forces act upon populations to change their allele and genotype frequencies. Therefore, populations are the unit of evolution and change genetically over time, not the individuals. Population ecology studies the size of a populations and the trends and causes of changes in the populations over time.
