KE REVIEW~ UNIT 5

Front

What is crossing-over?

Back

Crossing-over is a process during meiosis where homologous chromosomes exchange segments of genetic material, leading to genetic variation.

Front

What is the role of DNA replication in cell division?

Back

DNA replication is the process by which a cell duplicates its DNA before cell division, ensuring that each new cell receives an identical copy of the genetic information.

Front

What are chromosomes?

Back

Chromosomes are long strands of DNA that contain genes, which are the units of heredity.

Front

What is the difference between an allele and a gene?

Back

A gene is a segment of DNA that codes for a specific trait, while an allele is a variant form of a gene that can result in different traits.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is the significance of genetic mutations?

Back

Genetic mutations can lead to variations in traits, some of which may be beneficial, harmful, or neutral, and they play a key role in evolution.

Front

What is the function of RNA in cells?

Back

RNA (ribonucleic acid) plays a crucial role in translating genetic information from DNA into proteins, which perform various functions in the cell.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is the process of cytokinesis?

Back

Cytokinesis is the final stage of cell division, where the cytoplasm of a parental cell is divided into two daughter cells.

Front

What is the relationship between genes and traits?

Back

Genes are segments of DNA that code for specific traits, and the expression of these genes determines the traits observed in an organism.
