Chapter 9 Genetics
The composition of the culture medium used depends on the experiment and the
genotypes of the strains being used.
Minimal medium- each bacterium has a specific one that which it grows.
Complete medium- supplies vitamins and amino aci
The Little Science Behind The Island: Reproductive Cloning 101
Michael Bays action packed sci-fi thriller, The Island, was filled withwell,
because it was Michael Bay, helicopter crashes, lots of gun-slinging action, car chases,
Chapter 1 Genetics
genetics is the science of heredity.
genetics is central to bio because gene activity underlies all life processes from cell
structure and function to reproduction.
The principles of heredity were not understood until mid 19 century
Chapter 10 Genetics
The genetic info coded in DNA is responsible for determining the structure, function, and
development of the cell and the organism.
Miescher- discovered the nucleic acid.
Chromosome- the threadlike structures found in nuclei that ar
Chapter 11 Genetics
Semiconserved model- if the dna molecule was unwound and the two strands separated,
each strand would be a template for the synthesis of a new, complementary strand of
DNA that would remain bound to the parental strand. Each progeny m
Chapter 13 Genetics
Transcription is the synthesis of a single stranded rna copy of a segment of dna
Translation- the conversion of the mRna base sequencw info into the amino acid
sequence of a polypeptide.
Central dogma- dna->rna->protein. Transcripti
Chapter 14 Genetics
Translation of mRna- the conversion of the mRNA base sequence info into the aa
sequence of a polypeptide.
Protein- a high molecular weight, nitrogen containing organic compound of complex
shape and composition. It consists of one or
Chapter 15 Genetics
Mutation is the process by which the sequence of base pairs in a DNA molecule is
altered. It is a change in either a DNA base pair or a chromosome. They allow us to
DNA can be changed in a number of ways- thru spontaneous cha
Chapter 2 Genetics
Hereditary traits (characters) are sometimes the characteristics of an individual that are
transmitted from one generation to another.
Genotype- the genetic constitution of an organism.
Phenotype- an observable characteristic or set
Chapter 3 genetics
Diploid- two copies of each chromosome in the nucleus. 2N. diploid eukaryotes are
produced by the fusion of two haploid gametes, one from the female parent and one from
the male parent forming a zygote which then goes thru embryologica
Chapter 4 Genetics
Complementation test- determines whether two independently isolated mutations with the
same phenotype have affected the same or different genes. Also called the cis (same)
trans (across) test.
o Two mutations resulting in the same phe
Chapter 5 Genetics
Discontinuous traits- in each, the phenotypes were marked differently, and each
phenotype was easily separated from all other phenotypes. They have only a few distinct
phenotypes. The effects of variant alleles at the single locus are
Chapter 6 Genetics
Genetic recombination- recombinants are produced. Recombinants are nonparental
combos. Result from crossing over btwn homologous chromosomes during meiosis and
the close two genes are together the less likely there will be a recombinat
Chapter 7 Genetics
Tetrad analysis- mapping technique that can be used to map the genes of haploid
eukaryotic organisms in which the products of a single meiosis. It determines whether
two genes are linked based on the ways each tetrad type is produced w
Chapter 8 Genetics
Chromosomal mutations are variations from the normal wild type condition in
chromosome structure or chromosome number.
4 common types of chromosomal mutations involving changes in the chromosome struct.
o Deletions- involve a change i
Before reading the novel, two things always came to my mind whenever I heard
the words Jurassic Park: firstly, dinosaurs, second to that was the annoying little
ringtone that they played in the movie that always seemed to foreshadow someones
