Protein Synthesis CA

Front

What is a frameshift mutation?

Back

A genetic mutation that alters the reading frame of the DNA sequence, potentially changing all subsequent amino acids.

Front

Identify the three types of mutations: deletion, insertion, and substitution.

Back

Deletion removes a nucleotide, insertion adds a nucleotide, and substitution replaces one nucleotide with another.

Front

What happens at the end of the translation process?

Back

A chain of amino acids detaches from a ribosome, completing protein synthesis.

Front

Define transcription in the context of protein synthesis.

Back

The process by which the genetic information in DNA is copied into messenger RNA (mRNA).

Front

What is the role of tRNA in protein synthesis?

Back

tRNA carries amino acids to the ribosome and matches them to the codons on the mRNA.

Front

Explain the significance of codons in mRNA.

Back

Codons are sequences of three nucleotides in mRNA that specify which amino acid will be added during protein synthesis.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular machinery that facilitate the translation of mRNA into a polypeptide chain.

Front

Describe the process of translation.

Back

Translation is the process where ribosomes read mRNA sequences and assemble amino acids into a polypeptide chain.

Front

What is a silent mutation?

Back

A mutation that does not change the amino acid sequence of a protein due to redundancy in the genetic code.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.
