What is interphase in the cell cycle?

Back

Interphase is the phase of the cell cycle where the cell spends most of its time, growing and carrying out essential processes such as metabolism and DNA replication.

Front

Why do cells spend most of their time in interphase?

Back

Cells spend most of their time in interphase to grow and carry out essential processes such as metabolism and DNA replication.

Front

What is cell differentiation?

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type, allowing for various functions in the body.

Front

What allows cells to differentiate into various specialized types?

Back

Cells can differentiate because they express different genes at different times.

Front

What is the complementary strand of DNA for TTAACCGG?

Back

The complementary strand is AATTGGCC.

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What role does DNA polymerase play in DNA replication?

Back

DNA polymerase matches adenine with thymine and guanine with cytosine during DNA replication.

Front

What are the steps of DNA replication?

Back

Step 1: DNA polymerase matches adenine with thymine and guanine with cytosine. Step 2: Two identical double helices are formed.

Front

How do environmental factors influence gene activation?

Back

Environmental factors can influence gene activation by affecting the transcription of DNA to mRNA for translation into proteins.

Front

What is transcription in genetics?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which then translates into proteins.
