Questions and Answers

What are the potential sources of inheritable genetic variations described in the text?

Mutation due to radiation exposure (correct)
Random assortment of chromosomes during mitosis
Repair of damaged DNA strands
Aging-related changes in gene expression

Which process may lead to new genetic combinations as described in the text?

Meiosis in eukaryotic cells (correct)
Budding in yeast cells
Binary fission in prokaryotic cells
Mitosis in eukaryotic cells

What can result from viable errors occurring during replication as described in the text?

Insertion of foreign DNA sequences into the genome
Inactivation of tumor suppressor genes
Increased chromosome number in somatic cells
Substitution of one base pair for another (correct)

What are the three sources of inheritable genetic variations described in the text?

New genetic combinations through meiosis, viable errors occurring during replication, and mutations caused by environmental factors. Signup and view all the answers

Explain how viable errors occurring during replication can result in inheritable genetic variations.

Viable errors occurring during replication can lead to changes in the DNA sequence, which can be passed on to the next generation, resulting in genetic variations. Signup and view all the answers

Discuss the role of mutations caused by environmental factors in generating inheritable genetic variations.

Mutations caused by environmental factors can introduce changes in the DNA sequence, which, if inherited, can lead to genetic variations in subsequent generations. Signup and view all the answers

What is the role of cellular division (mitosis) in producing and maintaining complex organisms?

Cellular division (mitosis) is responsible for growth, repair, and asexual reproduction in complex organisms. Signup and view all the answers

How does differentiation contribute to the complexity of organisms?

Differentiation allows cells to specialize and perform specific functions, contributing to the complexity of organisms. Signup and view all the answers

Explain the interplay between cellular division (mitosis) and differentiation in the development of complex organisms.

Cellular division (mitosis) produces new cells, while differentiation gives these cells specialized functions, leading to the development of complex organisms. Signup and view all the answers
