Multiple Choice
What is the primary function of DNA in cells?
To control the cell's metabolism
To store genetic information
To regulate the cell's size and shape
To produce proteins
2.
Multiple Choice
What is the difference between introns and exons?
Introns code for proteins, while exons do not
Exons are non-coding sequences, while introns contain genetic information
Introns are removed from the pre-mRNA, while exons are spliced together to form the mature mRNA
Exons are found only in eukaryotic DNA, while introns are found only in prokaryotic DNA
3.
Multiple Choice
Which of the following is NOT a characteristic of introns?
They are transcribed into pre-mRNA
They are spliced out during RNA processing
They contain genetic information
They code for proteins
4.
Multiple Choice
What is splicing?
The process of synthesizing mRNA from DNA
The process of removing introns and splicing exons together to form mature mRNA
The process of translating mRNA into protein
The process of copying DNA into RNA
5.
Multiple Choice
