Feb 6th test Flashcards
Chromatin are what
chromosomes that spread out throughout the nucleus
Mitosis is a type of what
Asexual reproduction where a new nucleus forms identical to the original.
Interphase is when what
Cell prepares for division by making copies of all it’s genetic information
During prophase the chromosomes do what
Coll up and fold into chromatid pairs
The chromosomes line up sideways like an
X
Metaphase is what
chromatids line up in the center of the cell.
During anaphase the two halves do what
Separate
Chromosomes move apart toward
Opposite ends of the cell
During telophase a new nuclear membrane forms around each set of
Chromosomes
A new nucleus forms at
Each end of the cell
During cytokinesis the cytoplasm pinches in and
Two new cells form identical to the originail
Haploid are what
Reproductive cells that contain only half of the parents chromosomes.
Diploid are what
Occurs after joining of two haploid cells
Sexual reproduction is what
Reproduction of two parents
Mitiosis is a what step process
1 step
Meiosis is a what
2 Step process
Meiosis is what
Form of sexual reproduction
Fertilization is
The joining of a sperm and an egg
Egg is from what
Female
Sperm is made from who
Male
Fertilization produces a diploid called
Zygote
Proteins are what
Compounds involved in most cell fuctions
Enzymes are what
Are proteins that speed up chemical reactions
Nucleic acids are
Compounds that contain information about cell fuctions
The main form of Nucleic acid is
DNA
Respiration releases energy by
Breaking down glucose by using oxygen to create dioxide and water.
Fermentation is what
Releases energy from glucose without using oxygen
Heredity is what
The way in witch traits are passed down from generation
Homozygous when a person process what
possesses both dominant genes
Heterozygous
Person possess one dominant and one recessive gene
Allele
One member of a pair of genes on a chromosome in a specific position
Dominant Gene
Gene that shuts out the other instructions for the other gene
Recessive Gene
Gene that is shut out by the dominant gene
Genotype
Individuals internal gene make up
Phenotype
Individuals external appearance
Nobel prize winner on DNA
James Watson and Francis Crick
Genome
Humans complete genetic code
Founder of genetics
Gregor Mendel
Genetic engineering
Science of manipulating DNA
Gmo
Genetically modified organism
90% of corn
In USA is genetically modified
Cancer
Uncontrolled division of abnormal cells
Cancer calling agents
Carcinogens
Mutation
Change to a change in the structure of gens and DNA seqenes
