Biology EOC Practice 19-20

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the original cell.

Front

How many chromosomes do daughter cells have after mitosis if the parent cell has eight chromosomes?

Back

Daughter cells will have eight chromosomes each.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What can a mutation in mRNA lead to?

Back

A mutation in mRNA can lead to the production of a protein with a different identity or function.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell grows, duplicates its DNA, and prepares for mitosis.

Front

What are the three stages of interphase?

Back

The three stages of interphase are G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis.

Front

Which kingdom do multicellular eukaryotic autotrophs belong to?

Back

Multicellular eukaryotic autotrophs belong to the kingdom Plantae.

Front

What is a DNA fingerprint?

Back

A DNA fingerprint is a unique pattern of DNA fragments that can be used to identify individuals based on their genetic makeup.

Front

How can DNA fingerprints be used in paternity testing?

Back

DNA fingerprints can be compared between a child and potential parents to determine biological relationships.
