DNA and Protein Synthesis

Front

What is the role of DNA in protein synthesis?

Back

DNA contains the genetic instructions for the development and function of living things, and it directly affects the sequence of amino acids in a protein.

Front

What type of bonds hold the nitrogen bases in the DNA rungs together?

Back

Hydrogen bonds hold the nitrogen bases together in the DNA structure.

Front

Which nucleotide is complementary to adenine?

Back

Thymine is the nucleotide that is complementary to adenine.

Front

How many amino acids can be represented by a single 3-base DNA sequence?

Back

A single 3-base DNA sequence can represent 1 amino acid.

Front

What is the central dogma of molecular biology?

Back

The central dogma is DNA --> mRNA --> protein, describing the flow of genetic information.

Front

What are the four nitrogen bases found in DNA?

Back

The four nitrogen bases in DNA are adenine, thymine, cytosine, and guanine.

Front

What is the function 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 codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings the appropriate 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 mRNA.
