(a)
To determine:
That how the geneticists believe, even before direct experimental evidence was obtained, that the genetic code is composed of triplet sequences and be nonoverlapping.
Introduction:
The genetic information flows from the form of DNA into the form of protein and this framework is known as the central dogma of life. It involves three processes namely replication, transcription, and translation. The genetic code is the sequence of nucleotides present in the mRNA that specifically codes for a particular protein. Every three adjacent nucleotides present in the mRNA constitutes the unit called as a codon. Each three-letter codon specifically codes for the particular protein. For example AUG codes for methionine
(b)
To determine:
The experimental evidence that provides the initial insights into the compositions of codons encoding specific amino acids

That how an individual know that the initial transcript of a eukaryotic gene contains noncoding sequences that must be removed before accurate translation into proteins can occur.

- Find out about the organisations and the movements aimed at the conservation of our natural resources. Eg Chipko movement and Greenpeace. Make a project report on such an organisation.arrow_forwardWhat are biofertilizers and mention the significancearrow_forwardPCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.arrow_forward
- Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?arrow_forwardSelection of Traits What adaptations do scavengers have for locating and feeding on prey? What adaptations do predators have for capturing and consuming prey?arrow_forwardCompetition Between Species What natural processes limit populations from growing too large? What are some resources organisms can compete over in their natural habitat?arrow_forward
- Species Interactions Explain how predators, prey and scavengers interact. Explain whether predators and scavengers are necessary or beneficial for an ecosystem.arrow_forwardmagine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters? Which of these are examples of active transport?arrow_forward
