4 Nitrogen Bases of DNA
What are the pairs of DNA
A = ?
T = ?
C = ?
G = ?
A = T
T = A
C = G
G = C
What is the Helicase and what does it do?
It unzips the strand and unfolds the Double Helocase
How many strands of DNA are used in the transcribe process?
One strand of DNA is used to create mRNA molecule
What is the codon?
A sequence of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid
A bond that holds the Double Helix together?
Hydrogen Bond
What are the 4 Nitrogenous Bases of DNA?
Adenine, Thymine, Cytosine, and Guanine.
What do the proteins do in the Replication process?
The keep the strands from reattaching which would create a mutation.
What type of RNA is used in transcribing?
mRNA
What are the steps of Transcription?
Step 1 - gene gets unzipped by helocase
Step 2 - RNA polymerse creates mRNA
Step 3 - mRNA trvels out of nucleic membrane to ribosomes to then make protien.
Watson and Crick used this term to describe the shape of DNA.
What is a double helix?
What complementary base DNA has 2 Hydrogen bonds?
Adenine and Thymine
Has 2 hydrogen bonds and 2 connection
What are the two pieces of DNA stands after the helicase unzips them, what are they called, (the red and blue from the model)
Leading strand
Lag strand
What gets transcribed?
What is used to bring amino acids to the ribosomes?
tRNA
What are the 3 types of RNA
mRNA
rRNA
tRNA
What complementary base DNA has 3 Hydrogen bonds?
Cytosine and Guanine
They have 3 Hydrogen bonds and has 3 connections
Where does the Replication process take place?
In the nucleous
What are the base pair rules of transcription?
A-U
T-A
G-C
C-G
What reads the mRNA?
The ribosomes read the mRNA to create and order the protiens.
What type of RNA carries the amino acids to the ribosome?
tRNA
What are the complementary bases of the 4 Nitrogen Base of DNA?
Purines - Adenine and Guanine,
Pyrimidines- Cytosine and Thymine
This tells the DNA polymerase to begin adding new bases to the template LAGGING strand?
The RNA primase
Why does transcription take place?
DNA can not leave the nucleous which means it needs to be changed to mRNA to leave it.
Ifentify which amino acids will be translated from the following mRNA strand ... AUG CGG AAA UAG?
What are Methionine - Arginine - Lysine - STOP?
What is the difference between DNA and RNA.
DNA is double-stranded, forms a double helix, RNA is single-stranded.
