Read each question carefully and provide your best answer based on your understanding of Messenger RNA (mRNA) and its role in protein synthesis.
1. What is the primary function of Messenger RNA (mRNA)?
To carry genetic information from DNA to ribosomes
To transport amino acids to the ribosome
To form the structural components of ribosomes
To regulate gene expression
2. Which of the following is a key characteristic of mRNA?
It is double-stranded.
It contains deoxyribose sugar.
It contains uracil instead of thymine.
It is found only in the nucleus.
1. The process of synthesizing mRNA from a DNA template is called .
2. Each three-nucleotide sequence on mRNA that codes for a specific amino acid is known as a .
