Unit 5: DNA/RNA/Proteins/Mutations

Front

What is the structure of RNA?

Back

RNA is typically single-stranded, unlike DNA which is double-stranded.

Front

Where does translation occur in a cell?

Back

Translation occurs at the ribosome.

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What is the process of DNA replication?

Back

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

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.

Front

What is the function of ribosomes?

Back

Ribosomes are the cellular structures where protein synthesis (translation) occurs.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of copying DNA into mRNA, while translation is the process of synthesizing proteins from mRNA.

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in DNA and RNA is translated into proteins.

Front

What are the types of RNA involved in protein synthesis?

Back

The main types of RNA involved in protein synthesis are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).

Front

What happens during the process of transcription?

Back

During transcription, the DNA sequence of a gene is copied into mRNA.
