Topic 3 (Genetics) -- HW DUE 5/11 (make + memorize flashcards 18-20)
(15 cards)
What does DNA do
Carries the instructions for making proteins
How many bases does DNA have
4 bases A T C G
Where does DNA stay
DNA stays in the nucleus
Where is Protein assembled
In the ribosome
What does MRNA take from the DNA
MRNA takes the code from the DNA out of the nucleus
What does TRNA do in the ribosome
At the ribosome TRNA with its attached amino acid pairs up with the MRNA
What is the amino acid chain called
The amino acid is called a protein
How many genes does chromosomes have
They have a 1000 genes
What are chromosomes made out of
They are made out of DNA
Can hormones turn reproductive cells on or off
Yes they can turn reproductive cells on or off
Why does cells specialize/differentiate
The reason the cells specialize/differentiate because some genes are turned on/off
What is selective breeding
Humans choosing organisms to mate in order to get the desired traits in offspring
How can we make recombinant DNA
It can be made by cutting the DNA using special Enzymes and inserting genes into another organisms DNA
What is Gel electrophoresis
Fragments of DNA can be separated by size (small one goes through the gel faster then the larger ones
