A mutation caused by an addition or deletion of nitrogen base is a
point mutation
frame shift mutation
How many chromosomes does a normal human cell have?
23
46
48
52
Changing the sequence of nucleotides within a gene is known as
transmission mistakes
gene mutations
chromosomal mutations
transcription mistakes
Cancer is known as the uncontrollable dividing of cells; which statement appears to not support all the others in relation to the cause of cancer?
one or more genes controlling the enzymes that control the cell cycle are changed.
A protein can no longer make the proper enzyme to halt the division of a cell.
The segment of DNA that contains the gene to code for the proper enzyme has been changed.
Genes are not responsible for the ultimate causes of cancer.
Which of the following changes would be expected if a CAUUUG sequences of bases mutated to CACUUG?
the amino acid sequence would be shorter than expected
the identity of one amino acid would change
the identity of more than one amino acid would change
the amino acid sequence would remain unchanged
Refer to the image for this question.
mRNA #1 and mRNA #2
mRNA#1 and mRNA#3
mRNA #3 and mRNA #2
They are all the same
If the proteins above (from the mRNA sequences question) had an amino acid replaced with an amino acid with similar properties such as non-polar amino acid, the protein would most likely function the same.
