WorksheetsDNA and Protein Synthesis
Total questions: 30
Worksheet time: 17mins
In what process is mRNA synthesized?
Transcription
Translation
DNA Replication
Mitosis
Why must transcription occur in the nucleus?
because DNA can't leave the nucleus
because ribosomes are in the nucleus
because DNA polymerase is found there
because helicase unzips the DNA
How are DNA and RNA different? (CHECK ALL THAT APPLY)
Only DNA can leave the nucleus
RNA contains Thymine; DNA contains Uracil
DNA is double stranded, RNA is a single stranded
DNA contains Thymine, RNA contains Uracil
Which organelle contains rRNA and reads the mRNA to synthesize a protein?
Ribosome
Nucleus
Cytoplasm
Nucleotide
Choose the sequence of the mRNA strand that would match up with to the following DNA strand:
GTACAT
CATGTA
GAUCUA
CAUGUA
CUTGTU
What brings the amino acids to the ribosome to assemble a protein?
DNA
How many nucleotides code for 1 amino acid?
1
2
3
4
When these bond together, they form a protein
Amino Acids
Peptide Bonds
Ribose
Nucleotides
Which anticodon would be placed in spot #2
GGC
CCA
GGA
GGT
Which process does this diagram illustrate?
transcription
DNA replication
translation
What determines the shape and function of a protein?
The sequence of amino acids
The type of ribosome that assembles the protein
The cell that manufactures the protein
True or False: mRNA contains anticodons and tRNA contains codons.
True
False
How can a mutation in the DNA sequence result in NO change to the protein that is made?
There are multiple codons that can code for the same amino acid and result in the same protein
There is always a change in the protein when a mutation occurs
Only the mRNA is used in protein synthesis so a mutation in the DNA would have no effect on the protein
What is the first step in protein synthesis?
(a)
Which form of RNA carries amino acids from the cytoplasm to the ribosome?
(a)
Transcribe the following sequence of DNA into RNA:
AAG CTT TGC
(a)
What would be the complementary DNA strand for the following nucleotide sequence?
TCG ATA CGA
(a)
Variations in DNA base sequences are called
mutations.
duplications.
replication.
none of the answers are correct
Which of the following images is a INSERTION?
One strand of DNA is ____ to the other side to form its structure
Translated
Transformed
Replicated
Transcribed
What is the process in which protein synthesis happens?
DNA-->RNA--> Proteins
DNA-->Proteins-->RNA
Protein--->DNA--->RNA
Protein Synthesis--> Transcription-->Translation
Translation takes place in the
Ribosome
Nucleus
Cytoplasm
Mitochondria
In mRNA, each codon specifies for a particular
nucleotide
Enzyme
Amino Acid
Monomers
tRNA has anticodons and amino acids attached to it
True
False
DNA is made up of
Ribosomes
Amino Acids
Nucleotides
None of these
