Fast and Curious Protein Synthesis and Mutations

Front

What is the base sequence of the original DNA segment for the mRNA sequence UGU CAA ACU CGA?

Back

ACA GTT TGA GCT

Front

What type of mutation occurs when one amino acid is replaced by another in a protein sequence?

Back

Substitution mutation

Front

What distinguishes DNA from RNA in terms of sugar composition?

Back

DNA contains deoxyribose and RNA contains ribose.

Front

What is a substitution mutation?

Back

A mutation that results when a single nucleotide is exchanged for a different nucleotide.

Front

What does the arrow in a translation diagram typically represent?

Back

An amino acid chain.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the process of transcription?

Back

The process of copying a segment of DNA into mRNA.

Front

What are codons?

Back

Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids.

Front

What is the significance of the start codon in translation?

Back

The start codon (AUG) signals the beginning of protein synthesis.

Front

What is the function of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome and matches them to the codons in mRNA.
