Which of the following statements describe how technology and research changed the understanding of genetics? Select all that ap

andrey2020 [161]

Answer:

Past genetic knowledge has mostly been replaced.
Early researchers were hampered by a lack of knowledge of DNA structure and function.

Explanation:

Genetics is the part of biology that studies heredity, that is, how traits are passed down from generation to generation. Many technologies have been created so that scientific research can find new genetic discoveries and facilitate our understanding on this subject.

The first scientific research that tried to explain genetic phenomena was created long ago, but this research generated an archaic knowledge that can be replaced thanks to technology and scientific advancement in this area. This archaic knowledge is the result of research where researchers were unaware of the existence of the DNA molecule, which is the main vehicle in the transmission of heredity.

Unbeknownst to DNA, these researchers attributed heredity to elements that do not correspond with what actually happens, but we cannot dismiss the importance of such research for the technologies and genetic knowledge we have today.

The biome is a community of plants and animals (flaura & fauna).
Community: A community is a group of people/living beings who live in a specific location. It is used to describe two or more populations of different species that exist at same place.
