Question

The genetic material must be stable enough to maintain information in __________ from one cell to the next and one organism to the next.

Answer 1

The genetic material, primarily DNA, must be reliably stable to maintain information during replication from one cell to the next and across generations. This stability allows for the continuity of species and the inheritance of traits. DNA replication is a high-fidelity process crucial to vertical gene transfer and hereditary characteristics.

Step-by-step explanation:

The genetic material must be stable enough to maintain information in replication from one cell to the next and one organism to the next. Genetic material, primarily in the form of DNA, is the blueprint for building and maintaining an organism. During the cell cycle, DNA replicates, ensuring that each new cell has the same genetic information as the parent cell.

In sexually reproducing organisms, genetic information is also passed from parents to offspring through meiosis and fertilization, resulting in the transmission of hereditary characteristics. This process of vertical gene transfer is vital for the continuity of species, and any changes within the genetic code can lead to a mutation which, if inherited, can contribute to the evolution of species.

DNA replication occurs with high fidelity to minimize errors, but when errors do occur and are passed on, they become a source of genetic variation. The continuity of a species and the preservation of its unique characteristics are thus maintained through the precise and stable transfer of genetic information from one generation to the next.

Answer 2

Genetic material like DNA must be stable to ensure the accurate transmission of genetic information from one cell to another, and from one generation to the next. This process allows for the inheritance of traits and the continuity of species through vertical gene transfer.

Step-by-step explanation:

The genetic material must be stable enough to maintain information in sequence from one cell to the next and one organism to the next. This stability is crucial because DNA carries the genes that determine all inherited characteristics. It is replicated with accuracy during cell division, ensuring that both daughter cells receive the complete set of genetic information. Mutations in this genetic material can lead to evolution over generations.

Cells transmit genetic information through the process of DNA replication, which occurs before cell division, so that each daughter cell inherits a complete copy of the parental DNA. This transmission is known as vertical gene transfer and is fundamental to the preservation and continuum of species. Prokaryotes and eukaryotes have different genomic structures but the underlying principle of DNA as the repository of heritable information is consistent across all forms of life.

Connection for AP Courses

For students in AP Biology, understanding that DNA and sometimes RNA are the primary sources of heritable information aligns with the concepts in the curriculum. From bacteria's single circular chromosomes to humans' multiple linear chromosomes, genetic information's replication and transfer through cell division mechanisms (mitosis or meiosis plus fertilization) are key to the perpetuation of species.
