What is the process in which mRNA is synthesized?

Back

Transcription

Front

How do mutations contribute to a species' survival in a changing environment?

Back

Mutations are a source of variation in the species.

Front

What is the correct order of Protein Synthesis?

Back

Transcription -> Translation -> Protein

Front

How many nucleotides correspond to one amino acid?

Back

3

Front

What is a codon?

Back

A set of 3 nucleotides on mRNA.

Front

What is DNA?

Back

Deoxyribonucleic acid, the molecule that carries genetic information.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where translation occurs, synthesizing proteins from mRNA.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.
