Match the type of RNA with its function
-Chromosome inactivation

Question

Quizplus · Accepted Answer

Chromosome inactivation is carried out by a type of RNA called Xist (X-inactive specific transcript) RNA. Xist RNA coats one of the X chromosomes in females and causes it to be silenced.

Answer: A 
 The type of RNA that carries information for amino acid sequence is messenger RNA (mRNA). mRNA is transcribed from DNA and then translated into protein by ribosomes.

Answer: C 
 The type of RNA that is involved in protein synthesis is messenger RNA (mRNA). mRNA carries the genetic information from DNA to the ribosome, where it is translated into an amino acid sequence to form a protein.

Answer: E 
 The type of RNA that is involved in splicing is small nuclear RNA (snRNA). snRNA is involved in the processing of pre-mRNA, which includes splicing out introns and joining together exons.

Answer: G 
 The type of RNA that is involved in the regulation of cellular processes is microRNA (miRNA). miRNA can bind to mRNA and prevent its translation, thereby regulating gene expression.

Answer: F 
 The type of RNA that is involved in negative regulation is small interfering RNA (siRNA). siRNA can bind to mRNA and cause its degradation, thereby preventing gene expression.
