Both DNA and RNA are polymers composed of the same basic subunits called -
sugars
nucleotides
amino acids
lipids
Which process is responsible for copying the information found in an organism’s genome into strands of RNA?
translation
mitosis
transcription
photosynthesis
Before DNA can be transcribed, the DNA must unwind and separate between the –
nitrogen bases
phosphate groups
carboxyl groups
deoxyribose sugars
DNA is unwound and transcribed through the action of –
vitamins
polysaccharides
cytochromes
enzymes
Which of the following nucleotide sequences could not represent a segment of RNA?
GGC
CUA
TTG
GUC
Chemical signals are detected by receptor proteins in the cell membrane which triggers a cascade affect. This causes a formerly unexpressed gene to activate. This sequence of events demonstrates that the expression of genes is –
spontaneous
regulated
random
unmediated
Which arrow to the right represents transcription?
A
B
Which arrow above represents translation?
A
B
In eukaryotes, transcription occurs inside of the -
mitochondrion
ribosome
nucleus
vacuole
The translation of proteins is directed and organized primarily through the action of –
lysosomes
ribosomes
vesicles
Golgi bodies
Within a nucleic acid, information is organized into specific codons. How many nucleotides are found within each codon?
2
6
4
3
Each codon found on a strand of mRNA codes for a single amino acid. The amino acid is identified based on which characteristic of the codon?
the number of nucleotides
the sequence of nitrogen bases
the amount of thymine present
the type of sugar found in each nucleotide
A gene from one species can be spliced into the genome of an entirely different species and the protein will be made correctly. This provides evidence that the genetic code is –
different in every cell
variable between species
the same in all living things
unique to each organism

What is the sequence of amino acids that will be translated from the mRNA?
5' GUA UUG UCA CAA 3'
valine - leucine - serine - glutamine
valine - phenylalanine - serine - histidine
glycine - leucine - serine - glutamine
valine - leucine - serine - histidine
What is the sequence of amino acids that will be translated from the mRNA?
5' CUA GGU UGA AAA 3'
leucine - glycine - STOP
leucine - glycine - STOP - lysine
leucine - glycine - cysteine - lysine
leucine - glycine - tryptophan - lysine
For the section of DNA above, use the coding strand to determine the sequence of amino acids in the polypeptide.
*HINT: transcribe to mRNA, then translate into amino acids! You may need a piece of scratch paper.
alanine - leucine - STOP
alanine - leucine - STOP - isoleucine
arginine - aspartic acid - isoleucine - tyrosine
arginine - glutamic acid - isoleucine - tyrosine
