What is the process of transcription in DNA?

Back

Transcription is the process by which the information in a DNA sequence is copied into a complementary RNA sequence.

Front

What are the four bases of DNA?

Back

The four bases of DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts that speed up biochemical reactions by lowering the activation energy required for the reaction to occur.

Front

What are the monomers that make up proteins?

Back

The monomers that make up proteins are amino acids.

Front

What is mitosis?

Back

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

Front

What is the structure of a nucleotide?

Back

A nucleotide consists of three components: a phosphate group, a sugar molecule (deoxyribose in DNA), and a nitrogenous base.

Front

How do enzymes affect the activation energy of a reaction?

Back

Enzymes decrease the activation energy of a reaction, making it easier for the reaction to occur.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis, where amino acids are assembled into proteins based on the sequence of mRNA.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for growth, development, and repair in organisms, ensuring that cells divide and replicate accurately.
