Yearly Year 10 Where Did We Come From Flashcards
What is a gene
The location on chromosome
What is a chromosome
Long section dna
what is a allele
different codes at gene locations
what does homozygous
a pair of genes that are the same (TT)
what does heterozygous
a pair of genes that are different (Tt)
what does genotype mean
refers to the types of genes and their effects
what does phenotype mean
refers to how something looks
what does dominant gene mean
it means this gene masks recessive genes
what does recessive gene mean
it means this gene can be masked by dominate genes
what does trait mean
a distinguishing quality or characteristic
what is a mutation
the changing of the structure of a gene, resulting in a new form w, caused by the alteration of single base units in DNA
what do mutations do to someones to genetic code
mutations can sometimes have no affect on DNA, but sometimes it can effect the coding of amino acids which can affect what proteins are produced
what did Mendel do
Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
what did Mendel’s discovery and research impact the world
Gregor Mendel, discovered the fundamental laws of inheritance.
what are the the fundemental laws of inhereitance
genes come in pairs and are inherited as distinct units, one from each parent
how do pedigree charts help predict genetic patterns
they allow us to see where specific traits came from
what is recombinant DNA Technology
technology that dissects and joins together DNA molecules from two different species that are inserted into a host organism to create a new genetic combination
List 5 examples of Recombinant DNA Technology
Diagnosis of genetic disease Identifying DNA from fingerprints Gene therapy synthesis to create human insulin hepatitis B vaccine
what are some advantages to Recombinant DNA Technology (4)
crop environment
medical reasons
species cross breeding and revival
create transgenic animals to extract higher resources
