NC Biology EOC Review 2

Front

What is mitosis?

Back

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

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

How are mitosis and meiosis similar?

Back

Both require DNA replication before cell division.

Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy in the form of glucose.

Front

What is a mutation in mRNA?

Back

A mutation in mRNA is a change in the nucleotide sequence that can affect protein synthesis, potentially altering the protein's structure and function.

Front

What role does mRNA play in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where it serves as a template for assembling amino acids into proteins.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite external changes.

Front

How does sweating help maintain homeostasis?

Back

Sweating helps regulate body temperature by releasing heat through evaporation, cooling the body down during exercise.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports specific amino acids to the ribosome, matching them to the corresponding codons on the mRNA.

Front

What is the significance of the sequence of nitrogen bases in mRNA?

Back

The sequence of nitrogen bases in mRNA determines the order of amino acids in a protein, which ultimately affects the protein's function.
