What is RNA responsible for?

• Carrying the genetic code for making proteins from the nucleus to the cytoplasm

• Copying a DNA molecule to make another DNA molecule

• Making mRNA from DNA

• Transferring material

What is the process of copying a DNA molecule to make another DNA molecule called?

• Transcription

• Translation

• Replication

• Mutation

What is the process of making mRNA from DNA known as?

• Replication

• Translation

• Transcription

• Reduction

What is Translation in the context of biology?

• The process by which organisms adapt to their environment

• A permanent change in the sequence of DNA

• A process of making a protein from RNA

• The process by which organisms with variation survive better in their environment

What is a Mutation?

• A process of making a protein from RNA

• A slight difference in an inherited trait among individual members of a species

• The process by which organisms with variation survive better in their environment

• A permanent change in the sequence of DNA, in a gene or a chromosome

What is Variation in genetics?

• A process of making a protein from RNA

• A permanent change in the sequence of DNA

• A slight difference in an inherited trait among individual members of a species

• An inherited trait that increases an organism's chance of survival and reproduction

What is Natural Selection?

• The process by which organisms adapt to their environment

• A permanent change in the sequence of DNA

• A process of making a protein from RNA

• The process by which organisms with variation that help them survive in their environment, live longer, compete better, and reproduce more, than those that do not have the variation
