Question		Answer
A DNA sequence ATT CCG was mutated during replication and turned into ATT CCG A. Which mutation most likely occurred start learning		insertion
What are nucleotides made of? start learning		sugar, phosphate, nitrogen base
Shape of DNA start learning		double helix
Why is it important that DNA is held together by weak hydrogen bonds? start learning		it helps the DNA strands unzip easily to be replicated
If a DNA sample contains 30% A, then what % of G is there? start learning		20%
A DNA sequence, ACG, mutated into AC. Which mutation happened start learning		deletion
1 codon start learning		1 amino acid
The backbone of the DNA molecule is made of start learning		phosphate
What is the tRNA's job in protein synthesis? start learning		To bring the Amino acid
Genes contain the information to produce start learning		proteins
Which is the correct order of protein synthesis start learning		transcription--> translation
Which RNA makes ribosomes start learning		rRNA
This RNA copies the instructions on how to make proteins from the nucleus start learning		mRNA
the mRNA-->tRNA step is which step in protein synthesis start learning		translation
The DNA being coded into mRNA is start learning		transcription
An RNA sequence contains six nucleotides. How many amino acids does it carry? start learning		two
This type of mutation changes all of the amino acids in the sequence after it occurs start learning		frame shift
DNA stands for start learning		Deoxyribose Nucleic Acid
4 nitrogenous bases start learning		A, C, T, G
Chromosomes start learning		where DNA is found within the nucleus
central idea of molecular biology start learning		DNA-->RNA-->Proteins
proteins determine start learning		the structure and function of your cells
RNA start learning		take the information for making proteins for the DNA to the ribosomes
mRNA start learning		messenger (copies info) (DNA-->cytoplasm)
rRNA start learning		ribosomal (creates ribosomes)
tRNA start learning		transfer (brings amino acids to ribosomes to make proteins)O
start learning		phospate, nitrogenous base, sugar
backbone is made of start learning		phosphate
transcription start learning		DNA-->RNA step
3 steps to transcription start learning		initiation, elongation, termination
initiation start learning		DNA unwinds to be copied into mRNA
elongation start learning		when RNA nucleotides are added
termination start learning		mRNA strand complete
amino acids start learning		make up proteins
3 nucleotides is start learning		1 codon/amino acid
start codon start learning		AUG
stop codon start learning		UAG, UGA, AND UAA
translation start learning		RNA-->protein step
tRNA carries an start learning		anti-codon that matches the codon on the RNA strand
tRNA temporarily binds to mRNA while start learning		amino acids bind to mRNA
mutation start learning		an alteration of the intended DNA seqence
addition/insertion start learning		end up with more nucleotides than you start with
deletion start learning		end up with less nucleotides than you start with
substitution start learning		end up with the same number of nucleotides
most mutations are start learning		neutral/harmless
silent mutations start learning		harmless
frame shift mutations start learning		very bad, addition/insertion or deletion that causes amino acid sequence to be altered
point mutation start learning		only one point in the sequence in changes
