kingdom fungi Flashcards
Are Fungi prokaryotic or eukaryotic?
Eukaryotic
What is the main structural component of fungal cell walls?
Chitin
How do Fungi obtain reproduce?
By releasing spores (asexual and sexual reproduction).
How do Fungi obtain nutrients?
Heterotrophic – they decompose organic matter (saprophytic) or live as parasites.
Name an example of a useful Fungus.
Penicillium (used to make penicillin)
Genetic engineering also known as genetic modification.
•It is the direct manipulation of genes in an
organism.
•The relevant gene from a cell in one organism is
transferred to a cell of another.
•The organism that receives the
gene is genetically
modified and is known as a transgenic organism.
How does genetic engineering work?
Genetic engineering replaces faulty or missing genes that cause disorders or diseases.
Ensures that the correct protein is synthesized.
Relevant gene is identified in a healthy cell
extracted and cut from the DNA.
is inserted into a defective cell by of vectors (viruses and bacteria) The isolated gene means
It becomes integrated in the organism’s genome.
The correct protein is synthesized and the desired trait is expressed in the phenotype.
Results in the formation of new DNA sequence in the recipient cell. The formed DNA is
Known as recombinant DNA
