Biology Quiz

What is the role of an active gene?

• A gene that is permanently turned off

• Genes that can be turned on or off, and if on, they go through protein synthesis

• A segment of DNA that does not code for any protein

• The process by which cells become different types of cells

What is cell differentiation?

• The division of a cell into two identical daughter cells

• The process by which cells become different types of cells, each with its own "job"

• The unique pattern of gene modifications in an organism

• The process of tightly coiling DNA around proteins

What is the function of centrioles in animal cells?

• They replicate DNA

• They synthesize proteins

• They help arrange and separate chromosomes during mitosis

• They pass traits from parents to offspring

What is chromatin?

• The complete instructions for making an organism

• DNA loosely coiled around proteins, form of DNA during interphase

• A type of cell division

• A gene that is turned off all the time

What is a chromosome?

• A cell organelle that helps in cell division

• A protein that DNA wraps around

• A very long strand of DNA that contains many genes

• The process by which DNA makes a duplicate copy of itself

What is DNA replication?

• The process in which DNA makes a duplicate copy of itself

• The process by which a cell divides into two identical daughter cells

• The passing of traits from parents to offspring

• The process by which information encoded in DNA directs the synthesis of proteins

What is the epigenome?

• The process by which cells become different types of cells

• The complete instructions for making an organism

• The unique pattern of gene modifications possessed by each individual organism due to environmental factors

• A gene that is turned off all of the time

What is gene expression?

• The process by which cells divide into two identical daughter cells

• The process by which information encoded in DNA directs the synthesis of proteins

• The process in which DNA makes a duplicate copy of itself

• The passing of traits from parents to offspring

What is the genome?

• A gene that is turned off all of the time

• The process by which cells become different types of cells

• The complete instructions for making an organism, consisting of all the genetic material in that organism's chromosomes

• A very long strand of DNA that contains many genes

What does heredity refer to?

• The process by which a cell divides into two identical daughter cells

• The process by which information encoded in DNA directs the synthesis of proteins

• The passing of traits from parents to offspring

• The unique pattern of gene modifications in an organism
