Answer:
In most cells, DNA directs the production of a molecule of mRNA which then enters a ribosome. The ribosome produces the final product, a protein. Retroviruses do the opposite. They use the enzyme reverse transcriptase to use a template of mRNA to produce DNA.
Explanation:
The central dogma of molecular biology describes how a cell uses its genetic information to synthesize a protein. The first step called 'transcription' consists of using an RNA polymerase enzyme and a fragment of DNA (i.e., gene) as a template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, the genetic code in the mRNA sequence is read by the ribosomes in order to produce a protein, a process known as 'translation'. Retroviruses are viruses that have the ability to integrate into the host genome by using a reverse transcriptase enzyme that allows reverse transcription of mRNA to complementary DNA, which then integrates into the host's genome.

<h3>Question:</h3>
Words to Define:-
1) Sociobiologists
2) Hydrobiologists
3) Chronobiologist
4) Astrobiologists
5) Paleobiologists
<u>Answer</u>
Sociobiologists:- is a field of biology that studies and explains social behavior in evolutionary terms. Evolutionary anthropology, human behavioral ecology, and evolutionary psychology are all intimately related.
*************
Hydrobiologists:- is the science of life and living activities in water is known as hydrobiology. Much of current hydrobiology may be thought of as a branch of ecology. Taxonomy, economic biology, industrial biology, and morphology are all aspects of hydrobiology.
************
Chronobiologist: - a branch of biology that studies time mechanisms in living organisms, such as their adaptation to solar and lunar rhythms. Biological rhythms are the names for these cycles. Chronobiology is derived from the ancient Greek vo (chrónos, which means time) and biology, which is the study of life.
************
Astrobiologists: -is an interdisciplinary scientific subject that investigates the universe's origins, early evolution, dispersion, and future. Astrobiology investigates whether or if alien life exists, and if so, how humans can detect it.
************
Paleobiologists:-is a multidisciplinary area that incorporates methodologies and discoveries from both the earth and biology sciences. Not to be confused with geobiology, which studies the interactions of the biosphere with the physical Earth.
