Biology 106 Unit 1
Transcription - DNA to make RNA; the strand of DNA transcribes the RNA with A & U and C &G
together; when DNA is transcribed (in the nucleus), the result is an RNA molecule; genetic information is
transferred from DNA to RNA; DNA together then RNA polymerase comes in and separates the double
helix and the RNA is made; initiation--> elongation--> termination
DNA replication - copying mechanism bringing appropriate nucleotide to daughter DNA molecule;
strands meeting int he middle; making a step ladder; DNA polymerase reads the nucleotide and pull in
the complementary nucleotide to the one that exists; the result is an original parent strand with the new
daughter strand; they are identical
DNA - deoxyribonucleic acid; a chemical in cells that has the capacity to store genetic information;
keeper of the blueprints that make us who we are; a code that is contained within it that makes up the
proteins that make us who we are; can be copied and passed from generation to generation; it is in a
double helix that winds around; the dashed lines in-between the sides of the helix are created at the
bases of the nucleotides; the bond between is hydrogen bonding to the nitrogenous base
Process of Science - the word science means to know; science is a way of knowing; science
developes from people's curiosity about themselves and the world around them
Discovery Science - dependent on observations and measurements that others can verify; flow
from specific to general
Inductive Reasoning - a generalization that summarizes many specific observations; discovery
science
Hypothesis Driven Science - requires that ideas are testable by experiments that others can
repeat; flow from general to spcific
Scientific Method - as a formal process of inquiry this consists of a series of steps; we ask a
question and come up with a hypothesis; has to be testable; have to be able to prove that it is wrong if it
is
, Deductive Reasoning - reasoning that flows from general to specific; Hypothesis Driven Science
Hypothesis - a proposed explanation for a set of observations; an idea on trial; an educated guess
Theory - a set of statements to explain the observed facts; many experiments in order to say that
it is supported
RNA - ribonucleic acid; all three parts are very important in translation
mRNA - one of the three types of RNA; is the first ingredient for translation; actually contains the
codon
tRNA - one of the three types of RNA; acts as a molecular interpreter; carries amino acids;
matches amino acids with codon in mRNA using anitcodons
rRNA - one of the three types of RNA; involved in making up the parts of the ribosome
Polypeptides (proteins) - central dogma of molecular biology DNA--> this; consisting of a large
number of amino acids bonded together in a chain, forming part of or an entire one of these molecules;
they make us who we are
Differences between DNA and RNA - DNA is double stranded and RNA is single stranded; RNA has
uracil instead of thymine
Nucleotide - the building blocks of DNA and RNA that are made up of a phosphate+sugar+base
thymine (T), guanine (G), cytosine (C), adenine (A) - Four nucleotides for DNA
uracil (U), guanine (G), cytosine (C), adenine (A) - Four nucleotides for RNA
