inheritance Flashcards
What does transgenic mean?
Transfer of genetic material from one species to a different species
How does cloning work?
Cloned mammal process;
Nucleus removed from body cell
Remove nucleus from egg cell
Put nucleus from body cell into empty egg cell
Mild electricity shock
Then mitosis happens which forms an embryo
Place the embryo in the womb of a surrogate mother
example of something that reproduces asexually
runners
How does micropropagation work?
- small pieces (exoplants) cut from stems or side shoots of plant
- placed in agar growth medium, containing nutrients, minerals, plant hormones, and growth regulators
- when roots grow transferred to greenhouse
- put in pots w conditions like temp and humidity controlled
- small plants are clones
What are some of the benefits of micropropagation?
Quicker than seeds
Genetically identical to parent plant
Any time of year
Mrna contains G
the same bases as DNA expect thymine is replaced by uracil
Trna role in protein synthesis
to bring amino acids to the ribosome in correct order
Mrna purpose in protein synesthsies
s to carry coding information from Dna in the nucleus to the ribosome in the cytoplasm
DNA set of
three bases amino acid
Mrna set of
three bases codon
transcription
Mrna purpose is to carry coding information from Dna in the nucleus to the ribosome in the cytoplasm
translation
Trna is translation
Trna role in protein synthesis is to bring amino acids to the ribosome in correct order
Relationship between gene and characteristics?
Each gene code has a specific protein and proteins determine inherited characterises
How two proteins function
Each protien is coded by a different gene
Each code has a different sequences of bases
that code has a different number and order off amino acid
Which produce different proteins with different functions
XY =
