DNA, Protein Synthesis, and Mutations

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life. It is composed of two strands that coil around each other to form a double helix.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) serves as a template for protein synthesis by carrying genetic information from DNA to the ribosome, where proteins are made.

Front

What are the four nitrogen bases in DNA?

Back

The four nitrogen bases in DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is transcription in the context of DNA?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which then carries the genetic information to the ribosome.

Front

What is translation in protein synthesis?

Back

Translation is the process by which ribosomes synthesize proteins using the information carried by mRNA.

Front

What is a mutation?

Back

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

Front

What is the sugar found in DNA?

Back

The sugar found in DNA is deoxyribose.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil instead of thymine.

Front

What are hydrogen bonds?

Back

Hydrogen bonds are weak attractions between the nitrogen bases in DNA that hold the two strands together.

Front

What is a substitution mutation?

Back

A substitution mutation is a type of mutation where one base pair in the DNA sequence is replaced by another base pair.
