This was Lamarck's idea. Here's an example: Suppose giraffes originally had short necks that they stretched to reach high-up leaves in the trees. This continuous stretching of the neck was passed onto offspring, who as a result had slightly longer necks. This continued for multiple generations until we get today's long-necked giraffe. Lamarck was on to something (that something being evolution by natural selection, which Darwin discovered), but his theory wasn't completely correct since organisms can only pass on genes (segments of DNA that code for a characteristic or function) to their offspring. Since "stretching" would not code into DNA, it wouldn't be passed onto offspring, proving Lamarck's theory incorrect.
Answer:
I'm pretty sure the answer is A.
Explanation:
RNA is transcribed in the nucleus; after processing, it is transported to the cytoplasm and translated by the ribosome.

Answer:
<u>Polygenic therapies are more likely to show </u><u>unintended effects</u><u> in other regions of the genome likely resulting in harmful diseases.</u>

Explanation:
Gene therapy involves biotechnological techniques that add or remove gene sequences in the genome. These are typically used in eliminating harmful genes that cause genetic diseases or disorders and are generally thought to improve an individual's quality of life.
Polygenic traits are controlled by several genes. Similarly, polygenic diseases may be caused by variations in several gene sequences. These include hypertension, heart disease, and diabetes. Polygenic therapies are more likely to show unintended effects in other regions of the genome, leading to other deleterious disease-causing effects.
