Chapter 1.3 The Cell Flashcards
The simplest entity that can exist as an independent unit of life
Cell
What are the similarities between bacteria, yeast, skin cells, nerve cells and an egg
All cells contain a stable blueprint of information in molecular form
They have a discrete boundary that separates the interior of the cell from its exterior environment
They have the ability to harness materials and energy from the environment
………….. store and transmit information needed for growth, function, and reproduction
Nuclei acids
The information archive in all organisms is a molecule known as
DNA (Deoxyribonucleic acid)
The information encoded in DNA directs the formation of
Proteins
The synthesis of RNA from a DNA template is
Transcription
………..is the conversion of information stored in the language of nuclei acids to information in the language of proteins
Translation
The pathway from DNA to RNA to protein is called
Central dogma
The DNA sequence that corresponds to a specific protein product is
Gene
The membrane that separates the living material within the cell from the livibg environment around it is
Plasma membrane
Cells without a nucleus are called……………and cells with a nucleus are called…….
Prokaryotes
Eukaryotes
What makes prokaryotes so successful
Their small size
Their ability to reproduce rapidly
Their ability to obtain energy and nutrients from diverse sources
The three domains of life are
Bacteria
Archaea
Eukarya
Which of the domains of life are mostly single-called and lack a nucleus (prokaryotes)
Bacteria and Archaea
………converts energy from the environment into a form that can be used by cells
Metabolism
