Pro vs. Eu, Cell Cycle, & DNA Flashcard

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.

Front

What is contact inhibition in normal cells?

Back

Contact inhibition is a feedback mechanism that prevents cells from replicating when they are in contact with other cells.

Front

What happens to cells that lack contact inhibition?

Back

They will continue to grow, potentially causing a tumor in the body.

Front

How is information for a specific protein carried on the DNA molecule?

Back

As a sequence of nucleotides.

Front

What is the complementary DNA strand to a given DNA sequence?

Back

The complementary strand is formed by pairing adenine with thymine and cytosine with guanine.

Front

What is the role of DNA in cells?

Back

DNA carries genetic information necessary for the growth, development, and functioning of living organisms.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the structure of DNA?

Back

DNA has a double-helix structure formed by two strands of nucleotides twisted around each other.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis by translating messenger RNA (mRNA) into polypeptides.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within a cell that are enclosed by membranes, such as the nucleus, mitochondria, and endoplasmic reticulum.
