Front

Who is credited with discovering the shape of DNA?

Back

Rosalind Franklin is credited with discovering the shape of DNA, although Francis Crick and James Watson are often recognized for their model.

Front

What is the process of copying DNA onto mRNA called?

Back

The process is called Transcription.

Front

Can mutations lead to significant changes in a phenotype?

Back

Yes, mutations can lead to significant changes in a phenotype, but often they are almost unnoticeable.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable characteristics.

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in the organism's traits.

Front

What is the function of ribosomes in cells?

Back

Ribosomes are the cellular structures where protein synthesis occurs.

Front

What is the difference between transcription and translation?

Back

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