2. messenger
RNA – carries the instructions from the nucleus to the rivosome
3. ribosomal
RNA – makes up the ribosome
4. transfer RNA
– carries the amino acids and drops them off at the right spot (in the growing
chain)
5.
Transcription uses DNA as a template to make mRNA, nucleus
6. A codon is 3
bases (or nucleotides) in mRNA.
7. The mRNA code is read 1 codon at a time, and only in one
direction (beginning to end).
8. Translation
is changing from the language of mRNA to protein (the amino acids in the
correct order).
9. An anti-codon is part of the tRNA and it bonds with
cododn (base pairing) thus bringing in the proper amino acid.
10. mRNA
carries the instructions from nucleus to ribosome (TRANSCRIPTION), rRNA makes
up the ribosome, tRNA transfers the aminon acids (TRANSLATION).
OTHER SIDE:
1.
Griffith – transformation (harmless bacteria
changed into deadly bacteria)
a.
Avery – process of elimination, N.A. is the
genetic molecule
b.
Hershey/Chase – verification that DNA is genetic
moleuclue (virus infecting a bacterium)
2.
DNA
3.
It can be copied, read, and used
4.
A monomer of a nucleic acid (5-C sugar,
phosphate group, base)
5.
A-T
and C-G
6.
The DNA unzips, the matching base pairs line up
on both sides in opposite directions. You end with 2 double strands – each has
a new strand and an original strand
7.
Aatttgcat
8.
An abnormality/error in the DNA
9.
Neutral (not harmful nor beneficial)
