In guinea pigs, rough coat (R) is dominant over smooth coat (r). Predict the genotypes and phenotypes of the offspring and give the genotypic and phenotypic ratios is a homozygous dominant guinea pig is crossed with a heterozygous guinea pig. 3. ... In humans, brown eyes (B) are dominant over blue (b).
The RNA world hypothesis states that the earlier life-forms had relied only on RNA (Ribonucleic Acid) for the purpose of catalyzing the chemical reactions, and storing the genetic information. This hypothesis was proposed by Leslie Orgel, Carl Woese, and Francis Crick.
This hypothesis states that long before the living forms evolved to use DNA as the genetic storage material, the RNA molecules served the purpose of both storing the genetic information and carrying out catalysis, but because of its instability, DNA evolved.
Hence, the answer is RNA world hypothesis.
Answer:
B
the trna will not be recognized by trna synthetase and cannot be charged
Genetically modified (GM) foods are the ones came from organisms whose genetic material (DNA) are altered as they do not occur naturally. Food shortage, cost, variety can make people support the GM foods, while, religious beliefs, allergy, and worrying about the food can limit the support for these foods.
<h3>What are the characteristics of GM foods?</h3>
Genetically modified (GM) foods are those derived from organisms the ones genetic material (DNA) has been altered as they do not occur naturally.
Its characteristics are:
- More nutritious food.
- Less use of pesticides.
- Faster growing plants and animals.
- Disease- and drought-resistant plants.
As food shortage, cost, variety can make people support the GM foods, while, religious beliefs, allergy, and worrying about the food can limit the support for these foods.
Thus, the correct option is A.
