Name the 3 key differences between DNA and RNA.

What are:

1) DNA has a deoxyribose sugar whereas RNA as a ribose sugar

2) DNA contains the nitrate-containing base thymine (T) while RNA has uracil (U)

3) DNA is double-stranded while RNA is single-stranded.

The base pair rule
What is .... A - T G - C
200
DNA transcribed to this
What is mRNA?
200
mRNA is "read" by this organelle to form a protein chain
What are ribosomes?
300
Replicate this sequence: ATCGCC

300
Base that is only found in RNA
What is U - uracil?
300
Enzyme that proofreads new DNA strands
What is DNA polymerase?
300
The base pair rules for transcirption.
What is ... A-U T-A G-C?
300
What are codons and what is it made of? Be specific.
Codons are three bases made up of (A, G, C, and/or U)
400
What are the three components of a nucleotide?
Phosphate group, sugar, and base (A, T, C, or G)
400
The START codon
What is AUG?
400
A change in DNA sequence (like a dropped nucleotide)
What is a mutation?
400
Why does transcription take place?
DNA cannot leave the nucleus and therefore must be transcribed to mRNA to leave the nucleus.
400
Type of RNA that "brings" amino acids to the ribosome
What is tRNA?

Give one reason why DNA is essential to life.
DNA is an organism's genetic code. DNA creates genetic diversity. Contains code of essential proteins.
