Unit 1 Flashcards
genome
all the DNA within a cell
gene
stretches of DNA that codes for a specific person
ARRANGED IN LINEAR ORDER TO CREATE CHROMOSOMES
evolution
change in characteristics within a population
natural selection
the THEORY that explains evolution
adaptation
traits that increase the fitness of an organism
more fitness=
more reproduction= more traits passed down
Taxonomy
branch of study that addresses the classification of organisms
father of taxonomy
Carl Linnaeus
Carl created the
TWO PART hierarchical classification system
How to write when classifying the homo sapiens
capitalize Homo and italicize or underline all
What are the three parts to the domain
bacteria, archaea, eukarya
When naming, the HOMO/SAPEIN name can be common and not specific?
Homo name can be common and repeated, Genus name is specific
science is process of _______, and is an approach to _________.
investigation, approach to understanding natural phenomenon
macromolecules
collection of molecules that combine to form larger molecules
Name the four main types of macromolecules
carbohydrates, lipids, proteins, nucleic acids
polymers
long train cars made out of monomers
dehydration reaction
builds molecules and lengths by the removal of water, energy is added
hydrolysis reaction
shortens the polymer and breaks it apart by the addition of a water molecule, bonds are being broken so energy is released
Name the monomer and linkage of PROTEINS
- amino acids
2. peptide bonds
Name the monomer and linkage of CARBS
- sugars
2. alpha and beta glycosidic links
Name the monomer and linkage of NUCLEIC ACIDS
- nucleotides
2. phosphodiester bonds
Name the monomer and linkage of LIPIDS
- subunits are fatty acids. chloresterol
2. triglycerides and ester bonds
acronym for the function of proteins!
DEMSSTR
The biggest function of proteins is ____.
enzymes!
enzymes are not __________ in the reaction, and can be repeatedly used
used up
Amino acids are made up of what two things
An amino group and a carboxylic acid
The property and function of the amino acid varies and depends on the
R group within the amino acid!
