What is the process of transcription in DNA?

Back

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).

Front

What base pairs with adenine (A) in RNA?

Back

In RNA, adenine (A) pairs with uracil (U).

Front

What is the ethical concern regarding cloning?

Back

An ethical concern about cloning is whether a human clone can lead a fulfilling life.

Front

What is the main purpose of artificial DNA in medicine?

Back

Artificial DNA can be used to produce proteins, such as insulin, for medical treatments.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of copying DNA to RNA, while translation is the process of converting RNA into a protein.

Front

What are the potential side effects of using artificial DNA?

Back

The potential side effects of using artificial DNA may include unknown health risks and complications.

Front

What is the role of mitochondria in cells?

Back

Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration.

Front

What is the significance of base pairing in DNA and RNA?

Back

Base pairing is crucial for the accurate replication and transcription of genetic information.

Front

What is the function of messenger RNA (mRNA)?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.
