Question

Match the following statements with rRNA, mRNA, or tRNA:
a. is the smallest type of RNA
b. makes up the highest percentage of RNA in the cell
c. carries genetic information from the nucleus to the ribosomes

Short answer

Part(a) tRNA is the smallest type of RNA

Part(b) rRNA makes up the highest percentage of RNA in the cell

Part(c) mRNA carries genetic information from the nucleus to the ribosomes

Step-by-step solution

Part(a) Step 1 : Given information

We need to find the smallest type of RNA

Part(a) Step 2 : Simplify

The smallest form ,of RNA is transfer RNA (tRNA), it has less than $100$ nucleotide units. It provides as a connection between nucleic acid nucleotide sequences and protein amino acid sequences.It accomplishes this by transporting an amino acid to the cell's rRNA as indicated by the mRNA codon sequence.
Protein translation requires the presence of tRNAs.

Part(b) Step 1 : Given information

We need to find which RNA makes up the highest percentage of RNA in the cell

Part(b) Step 2 : Simplify

Ribosomal RNA (rRNA) is contained in ribosomes and accounts for about $80\%$ of the total RNA in the cell. Transcription is the process through which DNA is transformed into RNA.
The three types of RNA widely distributed throughout the cell are m-RNA, t-RNA, and r-RNA.
In transcription, m-RNA plays a crucial function.
The message contained in the nucleotide sequences of mRNA is translated into specific amino acid sequences by t-RNA.

Part(c) Step 1 : Given information

We need to find which RNA carries genetic information from the nucleus to the ribosomes

Part(c) Step 2 : Simplify

From DNA to ribosomes, mRNA transports genetic information.
Protein synthesis takes place on ribosomes. mRNA is a type of RNA that transports genetic information from DNA to ribosomes.
Protein synthesis takes place on ribosomes.
Ribosomes are involved in the translation process.
