Question
Chapter 17, Problem 9TYU
Summary Introduction
To determine: The type of RNA and its functions, and fill in the blanks in the given table.
Concept introduction:
Some of the genes in a cell are transcribed into RNA and express themselves in the form of proteins. After transcription, primary transcript is formed. There are four types of RNA each playing its role during transcription and translation.

Students have asked these similar questions
At least three types of RNA are required for protein synthesis. Compare and contrast mRNA, rRNA, and tRNA by moving the
descriptions of their structure and function to the appropriate categories. Some phrases may describe all three types of RNA.
mRNA
in eukaryotes, can exist outside the nucleus
acts as an enzyme for peptide synthesis
composed of ribonucleic acid
rRNA
Answer Bank
moves amino acids to the site of protein synthesis
tRNA
contains nucleotide triplets that code for specific amino acids
has a convoluted structure with a three-base sequence called an anticodon
moves genetic information out of the nucleus and into the cytoplasm
mRNA, rRNA, and tRNA
Complete the following table:
Type of RNA
Functions
Transfer RNA (tRNA)
In a ribosome, plays a structural role;as a ribozyme, plays a catalytic role(catalyzes peptide bond formation)
