QUIZIZZ#9 DNA Mutations & Cancer Cells & Mitosis

When DNA makes a copy or replicates itself, identify the correct nitrogen base pairing

• A pairs with G & C pairs with T

• A pairs with U & C pairs with T

• A pairs with T & G pairs with U

• A pair with T & G pairs with C

The image shows the different parts of a NUCLEOTIDE; identify the statement that is correct

• A= phosphate B= 5 carbon sugar C= nitrogenous base

• A= 5 carbon sugar B= 5 phosphate C= nitrogenous base

• A= nitrogenous base B= 5 carbon sugar C= phosphate

• None are correct

If the DNA strand read ATGC, identify the correct DNA strand that would be opposite in the double helix

• TACG

• ATCG

• CGAT

• GATC

Identify the correct order for DNA replication

• DNA unwinds, Nitrogen bases added, 2 identical DNA molecules created

• Nitrogen bases added, DNA unwinds, 2 identical DNA molecules created

• 2 identical DNA molecules created, Nitrogen bases added, DNA unwinds

• None are correct

During TRANSCRIPTION (to write) of Protein Synthesis, if the DNA strand reads TACACT what would be correct mRNA strand

• UGAAUG

• AUGUGA

• ATGTGA

• TGAATG

During TRANSLATION (to read), if the mRNA reads AUGUGA what would the correct AMINO ACIDS be

• Stop, Met(start)

• Ile, Stop

• Met(start), Trp

• Met(start), Stop

When mutations occur sometimes NO change occurs in the formation of the protein. Identify which of the different MUTATIONS would this occur

• Silent

• Missense

• Nonsense

• Insertion or Deletion

When POINT MUTATIONS and/or FRAME SHIFT MUTATIONS occurs and the base in the DNA changes it leads to change(s) in the formation of the protein. Identify which of the different MUTATIONS would this occur

• Silent only

• Missense & Nonsense ONLY

• Missense, Nonsense & Insertion/Deletion

• None are correct

When POINT MUTATIONS and/or FRAME SHIFT MUTATIONS occurs and the base in the DNA changes it leads to change(s) in the formation of the protein. Identify the correct statement that pertains to these two types of DNA mutations

• Both could lead to phenotype changes

• Both have changes in the mRNA & Protein sequences

• Both could occur due to environmental factors & carcinogens

• ALL are correct

The original DNA strand reads TAC/CGA/TCA/ATT.

The mutated DNA strand reads TAC/CGA/TCA/ATA.

Determine if there a disorder has occurred and the type of mutation.

• Yes, type of mutation SILENT

• Yes, type of mutation MISSENSE

• Yes, type of mutation NONSENSE

• No, there was no change to the DNA
