Replication
what is the shape DNA results in
Double Helix
Which enzyme unzips the DNA strand at the beginning of transcription
the helicase
T/F transcription and translation both require RNA
T
what amino acid is UCU
Serine (Ser)
What makes up the sides and rungs of the double helix
sides=sugars and phosphate
rungs=one of the four nitrogenous bases
What are the corresponding bases that pair together
A=T
C=G
A sometimes pairs with U
What is T (Thymine) replaced within mRNA
U (uracil)
What is the start amino acid
AUG (met)
What amino acid is AAU
Asparagine (Asn)
What does DNA stand for
Deoxyribose acid
What is the difference between the leading and lagging strand
The leading strand is placed on top and synthesizes before the lagging strand
What is the end result of transcription
mRNA
How many bases (codons) translate to one amino acid
What two codons are Aspartic Acid (Asp)
GAU and GAC
What are the parts of the nucleotide
What is the third step of replication
helicase will form and attach to the lagging DNA strand and then will unzip the two strands
What does the mRNA do after transcription to prepare for translation
moves to the cytoplasm
How many amino acids are on a codon chart
20
What are the four Valine (Val) codons
GUU, GUC, GUA, GUG
Name the four full names of the nitrogenous bases
Adenine, Thymine, Cytosine, Guanine
What is the DNA polymerase
What is the name of the enzyme that pairs unzipped DNA with its complementary nitrogenous base
The Polymerase
explain what an amino acid is
a folded chain of proteins in patterns
how many stop codons are there and what are they
3-UGA, UAA, UAG
Name two differences between DNA and RNA
Deoxyribose v. Ribose
Double-stranded v. Single stranded
Contains Thymine v. Contains Uracil
