Answer:
Proteins with seven conserved "helicase domains" play essential roles in all aspects of nucleic acid metabolism. ...
Explanation:
Known or putative helicases are required for general transcription initiation and for transcription-coupled DNA repair, and may play important roles in elongation, termination, and transcript stability.
<u> Genetic bottle neck</u>
Explanation:
Genetic bottle neck is defined as an evolutionary event during which a population is drastically reduced to to a significantly smaller size within a short period of time.
A genetic bottleneck can result from various events such as natural disaster, hunting of a species to a point of extinction or habitat destruction to cause the death of large number of organism.
In the given situation a typhoon which is a type of natural disaster caused the population to reduce to a size of 20 individuals. Then we find that the allele frequencies were greatly changed and the allele for colorblindness became established.Hence, a large population of present day inhabitant are color blind.
So we can say that the population experienced a genetic bottle neck.
Answer:
At each level in a food chain, some energy is stored in newly made chemical structures, but most is dissipated into the environment. Continual input of energy, mostly from sunlight, keeps the process going. 3.4 Energy flows through food webs in one direction, from producers to consumers and decomposers.
Answer:
D
Explanation:
Benadryl can make you extremely tired and unable to focus on most things.
Answer:
The central dogma of molecular biology is DNA>RNA>protein.
The expression happens when the DNA is transcribed to RNA, and then translated to protein.
