Answer:
DNA to messenger RNA (mRNA) to protein.
Explanation:
Central Dogma is a term that refers to the two step process through which information flows from the sequence of DNA into a sequence of RNA (the process of transcription) and finally takes the form of proteins (the process of translation)
Francis Crick was the first scientist who proposed the term of "Central Dogma".
Significance of Central Dogma:
- This is the process that ensures that genetic information of all living organisms is preserved and transmitted without any alteration or changes into their offspring.
- It is a process that intricately explains the logical mechanism through which DNA stored in our chromosomes express themselves into functional forms called proteins.
- This was the process which let us know the important roles of molecules like ribosomal RNA, transfer RNA and messenger RNA in the process of protein formation.
- The process has immense importance in understanding the latest advances in RNA technology that can further help in investigation and diagnosis as well as treatment of many critical diseases.
Hope it helps!
Answer:
Nucleic Acids
Explanation:
Nucleic acids are DNA and RNA and they are the molecules responsible for containing the genetic material of all living beings. Thus, DNA and RNA are the molecules responsible for establishing the variability and different characteristics between dog breeds, through the genetic information that each of them houses.
In this case, among the options given in the question above, we can confirm that if Allen has studied the genetic material of dogs to better understand why there are so many different breeds, he must have studied nucleic acids.
Secondary succession generally takes place faster in comparison to primary succession as the substrate is already present. In the case of primary succession, there is no soil and it consumes much time to form.
Primary succession takes place in mainly lifeless regions, that is, the regions in which the soil does not possess the tendency of sustaining life as an outcome of various factors.
On the other hand, secondary succession takes place in the regions where a community that previously prevailed have been eradicated and is epitomized by smaller scale turbulence, which do not eradicate all the forms of life and nutrients from the environment.
None of the above because they are non pollutant
