DNA
What is the shape of DNA?
double helix
What shape is RNA in?
Single stranded / helix
Where does replication occur?
In the nucleus.
What is being transcribed?
DNA
What is the product of translation?
Amino acid chain - proteins
Where is DNA found in the cell?
The nucleus.
After messenger RNA leaves the nucleus, it goes to what structure to start replicating proteins.
Ribosome
What is the purpose of replication?
To duplicate DNA strands.
What is DNA transcribed to?
mRNA
mRNA is "read" by what organelle?
Ribosomes
Replicate this sequence: ATCGCC
TAGCGG
Which base can only be found in RNA?
U - uracil
How many nucleotides are in a codon?
Three
In transcription one of the four bases is exchanged for another base in RNA. What bases are being exchanged?
T in DNA is being exchanged for U in RNA
What are codons and what is it made of? Be specific.
Codons are three bases made up of (A, G, C, and/or U)
What are the three components of a nucleotide?
Phosphate group, sugar, and base (A, T, C, or G)
The start codon is?
AUG
What does each codon code for?
An amino acid
Why does transcription take place?
DNA cannot leave the nucleus and therefore must be transcribed to mRNA to leave the nucleus.
The amino acids are carried to the ribosome by transfer RNA. T or F?
True
In the helical structure, does the base Adenine combines with the base Guanine or the base Thymine?
Thymine
How many nucleotides are needed to specify 6 amino acids?
18 ... 3 per codon
Is replication the first or second or third step in the production of protein?
First step.
Does DNA leave the nucleus in transcription?
No.
What are the RNA codon sequences that match up with this DNA code? 'CCG-ATT-GCT'
GGC-UAA-CGA
