What happens to chromosomes during metaphase of mitosis?

Back

Chromosomes line up along the equator of the cell.

Front

What is the condensed form of DNA found during mitosis?

Back

Chromosome.

Front

What is the result of cells going through mitosis repeatedly without entering interphase?

Back

Cancer.

Front

What supports the hypothesis that RNA was the genetic material in the earliest organisms?

Back

Ribozymes are RNA that can self-replicate.

Front

Which phase of mitosis involves chromosomes being pulled apart?

Back

Anaphase.

Front

What is the role of the centromere in cell division?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined.

Front

What is cytokinesis?

Back

Cytokinesis is the process where the cytoplasm of a parental cell divides into two daughter cells.

Front

What occurs during telophase of mitosis?

Back

Chromosomes begin to decondense and the nuclear envelope re-forms around each set of chromosomes.

Front

What is the difference between chromatin and chromosomes?

Back

Chromatin is the less condensed form of DNA found in interphase, while chromosomes are the condensed form seen during mitosis.

Front

What is the significance of ribozymes in understanding early life forms?

Back

Ribozymes demonstrate that RNA can have both genetic and catalytic functions, supporting the RNA world hypothesis.
