DNA Mutations & Cancer Cells

Front

What is the correct order for DNA replication?

Back

1. DNA unwinds 2. Nitrogen bases added 3. 2 identical DNA molecules created

Front

Which divides faster: Normal Cell Division or Cancer Cell Division?

Back

Cancer Cell Division divides faster.

Front

What amino acids correspond to the mRNA sequence AUGUGA during translation?

Back

Met(start), Stop

Front

Identify the parts of a nucleotide: A= phosphate, B= 5 carbon sugar, C= nitrogenous base. Is this statement correct?

Back

No, the correct order is A= 5 carbon sugar, B= phosphate, C= nitrogenous base.

Front

What is the correct mRNA strand for the DNA sequence TACACT during transcription?

Back

AUGUGA

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein function.

Front

What is the role of DNA in cells?

Back

DNA contains the genetic instructions for the development and function of living organisms.

Front

What is the difference between a normal cell and a cancer cell?

Back

Cancer cells divide uncontrollably and can invade other tissues, while normal cells have regulated growth.

Front

What is transcription in protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes read mRNA to synthesize proteins.
