DNA And Protein Synthesis Flashcards
(5 cards)
1
Q
Major functions of DNA
A
Replicate itself
Contain the genetic code
Make RNA copies of parts of the genetic code
Undergo mutation- contributes to variation and evolution
2
Q
What is the basic structure of RNA
A
Nucleotide (ribose sugar, phosphate, base) Sugar-phosphate backbone 1 strand Bases present= A,U,C,G Base pairing= A-U, C-G
3
Q
Major functions of RNA
A
Makes a copy of the genetic code of one gene.
Carry information of amino acid sequence from genes to where proteins are assembled.
4
Q
Compare the structure of DNA and RNA
A
Sugar
RNA- single strand, ribose sugar, U instead of T, found in the nucleus and the rest of the cell.
DNA- 2 strands, dioxyribose sugar, only found in the nucleus.
5
Q
What is the basic structure of DNA?
A
Nucleotide (deoxyribose sugar, phosphate, base) Sugar-phosphate backbone 2 DNA strands Bases= A,T,C,G Complementary base pairing= A-T, C-G Double helix shape
