Daily TAKS Connection:
Replication, Transcription,
Translation
BIO(6): The student knows that the structures and
functions of nucleic acids in the mechanisms of genetics.
The student is expected to:


DNA synthesis (also called
replication)
DNA → DNA
Occurs in the nucleus
1.
DNA double helix unwinds;
2.
separates at hydrogen bond
between base pairs
DNA polymerase adds base
pairs to both strands
Adenine complements
Thymine

Guanine complements
Cytosine
Two “New” DNA molecules
formed– one strand original,
one strand new

3.
Question
1.) DNA passes information to new DNA during the
process of —
a.
replication
b. transcription
c. translation
d. osmosis
Question
2.) Which of the following must occur before DNA
replication can take place?
a. Translation of DNA into amino acids
b. Separation of the DNA molecule into
codons

8.) The diagram shows how an
mRNA molecule is synthesized.
What would be the most likely
result if a bacterial infection
stopped the production of the
RNA polymerase?
a. A protein could not be
manufactured.
b. A lysosome would digest the
cell.
c. Osmosis would not occur in the
cell.

in the cytoplasm.
Day 4 notes
“Translation”  Protein synthesis
 RNA → protein
 Occurs at the
ribosomes
 Codons (3 base
sequence) code for
amino acids

Use codon chart to
determine amino
acid

Amino acids link
together to form
protein
Day 4 Student Task
Using the codon chart,
transcribe the RNA nucleotide
sequence below:
UUCACGGAAUGG
Question
9.) RNA is used to code for proteins during the process
of —
a. replication
b. transcription
c. translation
d. osmosis
Question
10.)Translation (protein synthesis) takes place
in a cell at the –
a. nucleus
b. mitochondria
c. ribosome
d. cell membrane
