From DNA to RNA
Activating
What are the complementary base pairs? _A___-__T__ and __C__-__G__
Strategy
Complementary Base Strand: _TGCCAGATAAGCTTACCG___
Remember! DNA is held together by special _hydrogen bonds___.
These bonds can only form between certain bases called _base pairs___.
A can only bond with __T____
C can only bond with ___G___
Fill in the correct Base pairs below
A = ___T____, C = ____G_____, G = _____C_____, T =___A_______
Now write the “Complimentary Strand” underneath the following strand of
DNA:
DNA Strand 1 – A T T G C C T G C T A
DNA Compliment – T A A C G G A C G A T
REMEMBER!!
__Ribosomes__________________ are the site of protein synthesis
__Amino Acids___________________ are the building blocks of proteins
RNA stands for _Ribonuclease Acid__________________
RNA is made in the _in the nucleus_____________________.
RNA is important because DNA cannot leave the __nucleus__________.
__RNA____ takes the DNA’s instructions out of the ___nucleus_______.
RNA moves into the _cytoplasm______________ of the cell where there is
room to make ___proteins (protein synthesis) _____________.
Two locations of RNA:
a. Nucleus
b. Cytoplasm
-
RNA structure is similar to DNA it is made of
__nucelotides____________ because it is a _nucleic acid______.
-
3 parts to the nucleotide
1. Ribose Sugar
2. Phosphate
3. Nitrogenous Base (A, U, G, C)
-
There are 4 nitrogenous bases (HERE IS ONE DIFFERENCE!)
1. A
2. U
3. G
4. C
-
RNA looks like _half of a DNA_____________ because it only has
__one strand______________________
-
When it base pairs,
A can only bond with __U____
C can only bond with __G____
Here is a strand of DNA. Write the COMPLIMENTARY strand of RNA.
DNA Strand– A T T G C C T G C T A
RNA Strand – A U U G C C U G C U A
1. mRNA: (messenger RNA)-brings info from the DNA in the nucleus
to the cytoplasm
2. rRNA: (ribosomal RNA)- binds to the mRNA and uses the mRNA’s
information to assemble the amino acids in the correct order
3. tRNA: (transfer RNA)- transports single amino acids to the
ribosome to be assembled into a protein
