<span>The correct answer is B. Insertion. In this particular insertion there is an insert of three bases. Complementary strands in DNA are the opposite strand, so Adenine is coupled to Thymine and Guanine is coupled to Cytosine. So the complementary sequence (also called the antisense strand) of the original would be GTC GGC ATC, there's an extra 3 bases in there: ACA.</span>
Answer:
A
Explanation:
The correct answer would be that <u>de novo incidences of DiGeorge syndrome occur as a result of errors during maternal or paternal meiosis, creating a new variant.</u>
<em>Since the syndrome has high penetrance, it is highly unlikely that any of the parents would be misidentified or that one of the parents has the variant without symptoms. It is also highly improbable that both parents would be carriers because if they do, they will definitely show some symptoms.</em>
Hence, the most likely explanation is that the variant emerges as a result of errors during maternal or paternal meiosis leading to the formation of a gamete with the variant.
The correct option is A
Answer:
larger macroevolutionary patterns.
extinction, in which ecosystems change drastically
Explanation:
The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of larger macroevolutionary patterns. This larger macroevolutionary patterns occur due to climate change. Extinction of organisms in which ecosystems change drastically that leads to unfavourable environmental conditions which decreases the population to the extinction of organisms.
