DNA
What are the 4 purposes of DNA?
carries the instructions for cell growth, development, reproduction, and overall function.
what are 2 type of cells
Prokaryotic cells (bacteria) lack a nuclear envelope; eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm.
what is the most important thing in our human body
the brain
what is a the mitochondria
A mitochondrion is a vital organelle in cells, known as the "powerhouse" for generating most of the cell's energy, called ATP, by breaking down food molecules
what is a prokaryote
A prokaryote is a simple, single-celled organism (like bacteria and archaea) that lacks a membrane-bound nucleus and other specialized organelles
What is DNA
DNA is the molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of nearly all living organisms
Can humans live without T cells?
Without them, we can't survive
what porcentage is our human body made of water
60%
what is a nucleus
A nucleus is the central, membrane-bound organelle in eukaryotic cells, acting as the cell's control center by storing DNA
what is the diffrence between eukaryotes and prokaryotes
Eukaryotes have a true nucleus and membrane-bound organelles (like mitochondria, ER) for compartmentalization, making them larger and complex (plants, animals, fungi, protists); while prokaryotes (bacteria, archaea) lack a nucleus and organelles, having their DNA in the cytoplasm (nucleoid), are smaller, simpler, and always unicellular, using binary fission to reproduce.
What can we use DNA for?
DNA testing can also be used to identify pathogens, identify biological remains in archaeological digs, trace disease outbreaks, and study human migration patterns.
what is in a cell
water, inorganic ions, and carbon-containing molecules.
what is our body made of the most
oxygen, carbon, hydrogen, and nitrogen
what is a the cytoskeleton
The cytoskeleton is a dynamic network of protein filaments
what is a eukaryote
A eukaryote is an organism whose cells contain a membrane-bound nucleus and other complex organelles
What is DNA used for
DNA is used as the fundamental blueprint for all living organisms, containing the instructions to build, maintain, and reproduce life, by coding for proteins that determine traits and functions, enabling heredity from parents to offspring, and serving as a basis for genetic research, forensics, medicine, and biotechnology
How many cells are in a human body?
30 trillion
How many liters of blood are in a human body?
5 liters
what is a the endoplasmic reticulum
The endoplasmic reticulum (ER) is a vast network of membranes within a eukaryotic cell, acting as a cellular factory for making proteins and lipids, a transport system, and a calcium regulator
Are humans prokaryotic or eukaryotic?
eukaryotic
What is the main purpose of DNA?
DNA contains the instructions needed for an organism to develop, survive and reproduce
What are white blood cells?
White blood cells are part of the body's immune system.
how many bones dose an adult body have
206 bones
what is a the Golgi apparatus
The Golgi apparatus is a vital organelle in eukaryotic cells, acting as the cell's "post office"
what is science
Science is the systematic study of the physical and natural world through observation, experimentation, and evidence-based reasoning to build reliable knowledge about how the universe works, involving both a body of knowledge and a dynamic process of discovery
