Evolution accounts for the unity and diversity of life, and the continuity of life is based on heritable information in the form of DNA. In a short essay (100-150 words), discuss how the fidelity with which DNA is inherited is related to the processes of evolution. (Review the discussion of proofreading and DNA repair in Concept 16.2.)
Chromosomes pass genetic information from one cell to another in cell generation.
(j) Explain the relationship between DNA, genes, and chromosomes during the passing of genetic information.
(k) During the passing of genetic information from one generation to the next via chromosomes, nondisjunction can occur, interrupting the process. Describe the events that take place during nondisjunction.
One of the following is a characteristic of eukaryotic genetic material?
1. Eukaryotic genetic material is compacted by wrapping the double-helix around histone proteins to form nucleosomes.
2. Eukaryotic genetic material consists of supercoiled circular DNA molecules complexed with proteins into chromosomes.
3. Eukaryotic genetic material consists of relaxed linear DNA molecules complexed with RNA into a 30 nm fiber.
4. Eukaryotic genetic material is compacted by folding linker regions around non-histone proteins to form a scaffold.

- DNA contains the genetic information that controls all processes of heredity in a cell. The total length of all DNA in the cells of a human body can stretch to the moon and back four times.The terms that describe a length of DNA and the form in which it remains for most of its life, respectively are: Select one: a. Length of DNA Form in which it spends most of its time life Centromere Locus b. Length of DNA Form in which it spends most of its time life Chromosome Chromatin c.

Because cell division plays several important roles in life, it is important that the cycle be regulated.Which of the following are reasons the cell cycle must be regulated? Select all that apply.[ ]To make sure cells only divide when conditions are favorable for growth and development of the organism[ ]To make sure daughter cells end up with the right number of chromosomes[ ]To make sure daughter cells are genetically different from the parent cell[ ]To allow cells to respond to cues from their internal state and from their environment.arrow_forward

Which of the following is the best explanation for how DNA provides the code for physical traits and characteristics of humans, even though it never leaves the nucleus? * In the nucleus, the DNA is transcribed into mRNA, which can then leave the nucleus and be translated at the hbosome into proteins, which make up physical traits and characteristics. Under the right conditions, DNA turns into TRNA so it can leave the nucleus, then it is translated into proteins which make up physical traits and characteristics. Inside the nucleus, DNA is transcribed into TRNA, which is then translated into proteins. These proteins can then leave the nucleus and make up physical traits and characteristics. The DNA in the nucleus is translated into proteins, which are able to leave the nucleus and enter the cytoplasm, where transcription of rRNA can occur. The rRNA then makes up the physical traits and characteristics. AKS 5c1:…arrow_forward
