Protein Synthesis & Biotechnology

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) transports amino acids in the cytoplasm to the ribosome for protein synthesis.

Front

Which enzyme is responsible for adding free nucleotides during DNA replication?

Back

DNA polymerase is the enzyme that brings free nucleotides to create a new strand of DNA.

Front

What is the role of mRNA during transcription?

Back

mRNA (messenger RNA) copies the DNA and carries the genetic message out of the nucleus to the ribosome.

Front

What type of mutation is caused by insertions and deletions in the DNA sequence?

Back

A frameshift mutation is caused by insertions and deletions, altering the reading frame of the genetic code.

Front

What is ribonucleic acid (RNA)?

Back

RNA is a family of single-stranded nucleic acids that play a crucial role in protein synthesis.

Front

What is the primary function of rRNA in the ribosome?

Back

rRNA (ribosomal RNA) forms the core of the ribosome's structure and catalyzes protein synthesis.

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.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What is the process of transcription?

Back

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

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein function.
