Their poverty costs the country and the world through the loss of the island's endemic biodiversity. Madagascar's major environmental problems include: Deforestation and habitat destruction. Agricultural fires.
<span>Humans have the least control over their genetics. These are usually coded from the very beginnings of our existence and are items that are unlikely to be changed much due to personal actions and lifestyle choices. These can lead to health outcomes that are positive or negative, depending on the genetics at play.</span>
Answer and Explanation:
Gregor Mendel, the father of Genetics, designed different types of methodologies to study and understand how traits are inherited. Therefore, he wondered if he'd be able to predict the inheritance of a single trait and its association to a specific gene.
Through the Principle of Independent Assortment, he explained how genes segregate (or separate) in homologous chromosomes during meiosis. During this process, the alleles of different genes are sorted in gametes and inherited independently. This results in genetic diversity and recombination.
For instance, he tested green and yellow peas which were either wrinkled or smooth. <u>This principle states that the offspring could have 'mixed' traits, for example green and wrinkled, green and smooth, yellow and wrinkled, etc.</u>
Answer: Option B) The fidelity of DNA synthesis.
Explanation:
In DNA synthesis, some enzymes known as DNA polymerases, catalyze the addition of nucleotides to elongate the already formed DNA chain.
Then, 3'-5' exonuclease activity of DNA polymerase is introduced for proofreading i.e to remove wrongly paired nucleotides from the 3' end of the DNA chain.
Thus, 3'-5' exonuclease activity of DNA polymerase is critical for fidelity of DNA synthesis.
That principle is that cells are derived from other cells.
