Genetics Flashcards
What os DNA made of
Nucleotides
DNA replication:
Step 1: unzips
Step 2: Complimentary nucleotides attach to bases on DNA strands
Step 3: produces 2 new DNA molecules that are identical
Where does Protein Synthesis take place
Ribosomes
What controls the sequence of Amino acids
DNA
What is the function of DNA
It acts as a template for protein synthesis and for our genetic makeup
What is transcription
When DNA nucleotides are copied by mRNA in the NUCLEUS
Whats translation
When codes of nucleotides in THE RIBOSOME produce amino acids with the presence of tRNA
What does the chromosome theory state
That genes are arranged on a linear surface on a chromosome
What work did Mendel do
•Developed basic principles of heredity
w/o knowledge of chromosomes
Whats genetic engineering
New tech. that people use to alter the genetic make up
What is another word for genetic engineering
Selective breeding
RESTRIVIEEEE ENZYMEES !!
RESTRICTIVE ENZYMES
What are mutations
Changes in the genetic material
Deletion mutation:
A piece of chromosome is lost
Inversion mutation:
Piece of chromosome breaks off..flips around and them the piece reattaches
