DNA, RNA and Protein Synthesis

Front

What is a point mutation?

Back

A point mutation is a change in a single base pair in the DNA sequence.

Front

What is the role of deoxyribose sugar in DNA?

Back

Deoxyribose sugar is a component of DNA nucleotides, providing the backbone structure.

Front

What are the correct base pairs in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.

Front

How does RNA differ from DNA?

Back

RNA is single-stranded, does not contain Thymine, and has Uracil instead.

Front

Where does protein synthesis occur?

Back

Protein synthesis occurs on the ribosome.

Front

What is a frameshift mutation?

Back

A frameshift mutation is a genetic mutation caused by insertions or deletions of nucleotides that shift the reading frame.

Front

What is a nitrogenous base?

Back

A nitrogenous base is a molecule that contains nitrogen and has the chemical properties of a base; examples include Adenine, Thymine, Cytosine, Guanine, and Uracil.

Front

What is the function of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during protein synthesis.

Front

What is transcription in the context of protein synthesis?

Back

Transcription is the process of copying a segment of DNA into RNA.
