Which best describes the relationship between a parent cell and daughter cells in mitosis?(1 point)
Responses
Parent cells duplicate their DNA, then divide into daughter cells that are identical.
Parent cells duplicate their DNA, then divide into daughter cells that are identical.
Parent cells share new types of DNA to daughter cells to ensure diversity.
Parent cells share new types of DNA to daughter cells to ensure diversity.
Parent cells divide randomly, and daughter cells have varying amounts of DNA.
Parent cells divide randomly, and daughter cells have varying amounts of DNA.
Parent cells divide several times to ensure daughter cells have half of the parent cell’s DNA.

Use the image to answer the question.
The double stranded D N A inside the nucleus transforms into a single-stranded R N A through transcription. R N A becomes m R N A through splicing. From the nucleus, m R N A exports to cytoplasm, where, through the process of translation, it transforms into the A. A. chain that further becomes a protein through folding.
