Protein Synthesis

Front

What are the components of a DNA nucleotide?

Back

A DNA nucleotide is made up of a phosphate group, deoxyribose sugar, and a nitrogenous base (adenine, thymine, cytosine, or guanine).

Front

What is the role of codons in protein synthesis?

Back

Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids or stop signals during protein synthesis.

Front

What does the codon UAA signify?

Back

The codon UAA is a stop codon, signaling the termination of protein synthesis.

Front

Where can an anticodon be found?

Back

An anticodon is found on tRNA (transfer RNA) and pairs with the corresponding codon on mRNA.

Front

What is the start codon for protein synthesis?

Back

The start codon is AUG, which codes for the amino acid Methionine.

Front

How many nucleotides are in one codon?

Back

One codon consists of three nucleotides.

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 the difference between DNA and RNA?

Back

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

Front

What is the process of transcription?

Back

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

Front

What is the process of translation?

Back

Translation is the process of decoding mRNA to synthesize proteins at the ribosome.
