DNA Structure, Replication, and Protein Synthesis

Front

What is a codon?

Back

A codon is a three-base sequence of mRNA that codes for a single amino acid.

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is described as a double helix.

Front

What is the amino acid sequence for the mRNA code AUGCCAGUAUGA?

Back

The amino acid sequence is Met-Pro-Val.

Front

What is the lagging strand in DNA replication?

Back

The lagging strand is the strand that is copied in fragments during DNA replication.

Front

What is the semi-conservative model of DNA replication?

Back

The semi-conservative model states that each new DNA molecule consists of one old strand and one new strand.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is transcription in the context of protein synthesis?

Back

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

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes read mRNA sequences to synthesize proteins.
