class of org 1
How many cells do multi cellular organisms have?
more than one cell.
What is a common ancestor?
A single species or that that gives rise to multiple distinct organisms
What is taxonomy used for?
it is used to formally classify organisms.
What are Genes?
Segments of DNA that code for protein or functional RNA.
What is a genome?
the complete set of genetic material or genes in a cell or organism
What is the MAIN difference between unicellular cells and multicellular cells?
Unicellular cells are only composed of one cell
Do how do Heterotroph produce their own energy?
They don't, Heterotrophs must consume other organisms for energy.
What are the organisms in a lineage successful in?
They are successful in surviving and reproducing.
What is the purpose of genetic engineering?
To deliberately modify the DNA sequence of an organism by using genetic techniques
What is DNA sequence in a DNA molecule?
It is the precise ordering of nucleotides
What is DNA used for?
To carry genetic information present in nearly all organisms.
How do autotrophs produce their energy?
They make their own energy from sunlight or inorganic chemicals with different processes like photosynthesis.
How does a cladogram represent evolutionary descent?
By showing that groups of organisms come from a common ancestor.
How do clones look compared to the original organism or cell?
They look identical and are genetically identical
What is gene therapy used for?
using genetic engineering to translate genes into human cells to cure a disease or a genetic defect.
What does a prokaryotic cell lack?
a nucleus or any other membrane-enclosed organelle
What relationships does a Phylogenetic Tree show.
it shows evolutionary relationships based on the similarities and differences in their physical and genetic characteristics
What level is domain on the taxonomic level and what is it primarily based on?
It is the highest taxonomic level and is based on ribosomal RNA structure.
How does an organism become a GMO (Genetically Modified Organism)?
This happens when the organisms genetic material is altered using genetic engineering techniques.
How do genetic disorders happen?
It happens due to an error in the DNA sequence or by the presence or absence of specific alleles
What does a eukaryotic cells have that other cells don't?
They have membrane bound-organelles and a nucleus.
what does the phylogenetic tree display among biological species?
It displays the inferred evolutionary relationships and the difference in physical and genetic characteristics
Where is kingdom on the taxonomic classification and out of all the other ranks how much species and biodiversity does it have?
it ranks beneath domain and above phylum and has the highest biodiversity.
How did an organism become a Transgenic Organism?
By having a modified gene or a gene from another organism be inserted into it using genetic techniques.
What is Gel Electrophoresis used for?
It is used for DNA fingerprinting and other processes in which molecules migrate through a gel.
