Biology

Chemical substance that is an essential part of the structure of cells. Its main functions are to act in metabolism and as antibodies.

• DNA Bases

• Aminoacids

• Protein

• Nucleotides

Where is DNA found inside the cell?

¿What is an eukaryotic cell?

• Any cell or organism that share a clearly defined nucleus

• Has other membrane bound organelles

• Any cell or organism that possesses a clearly defined nucleus

• Has membranes but undefined.

How do new cells originate?

• This process is called cell division. One cell doubles by dividing into two

• When cells become damaged or die the body makes new cells to replace them

• Through meiosis

• This process is called cell combination of it is to create new life in a cell

• True

• False

___________ are large, complex molecules that perform many critical functions in the body it found also in the DNA.

What parts of the body are usually used to extract DNA?

• DNA samples from plants and many other animals are often extracted from blood or skin cells

• DNA samples from humans and many other animals are often extracted from hair and implants

• DNA samples from humans and many other animals are often extracted from membranes and fluids.

• DNA samples from humans and many other animals are often extracted from blood or skin cells

What are the functions of DNA?

• Replication, DNA exists in a triple-helical arrangement, each base along one strand binds to a separate base on the other strand.

• Contains the instructions needed for an organism to develop, survive and reproduce

• Replication in once.

  Gene structure.

  Mutation.

  Duplication.

• Carrying and dismissing hereditary materials or genetic instructions from parents to offspring

¿Who discovered DNA?

• Gregor Johann Mendel

• Johann Friedrich Miescher

• Charles Robert Darwin
