DNA
What shape is RNA in?
Single stranded / helix
DNA is always copied in this direction?
3' to 5'
What is being transcribed?
DNA
What is the product of translation?
Amino acid chain - proteins
What two types of bonds hold DNA together?
Hydrogen and Covalent
What sugar is in RNA?
Ribose
What is the base pair rule?
A - T G - C
What is DNA transcribed to?
mRNA
mRNA is "read" by what organelle?
Ribosomes
Which base can only be found in RNA?
U - uracil
What enzyme unzips the DNA double helix?
DNA helicase
The basics of transcription requires one base being exchanged for another base. Which bases are being changed? Be specific.
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)
The start codon is?
AUG
What enzyme makes the new DNA strand?
DNA polymerase
Why does transcription take place?
DNA cannot leave the nucleus and therefore must be transcribed to mRNA to leave the nucleus.
Which type of RNA "brings" amino acids to the ribosome?
tRNA
DNA must match in opposite directions so that the ____________ bonds between bases can hold them together. This is called _____________.
Hydrogen ----- Anti-parallel
How many nucleotides are needed to specify 6 amino acids?
What are 2 of the 3 other proteins are needed on the lagging stand to help copy in the correct direction.
Primase, DNA polymerase I, ligase
What is present on the DNA that indicates a gene needs to be transcribed.
Promoter
What are the anti codon sequences that match up with this DNA code? 'CCG-ATT-GCT'
'CCG-AUU-GCU'
