Question

which of the following is not a type of rna?
mrna
trna
nrna
rrna
question 2
which of the following sets includes all of the parts of an rna
ribose, phosphate, nitrogen base
thymine, adenine, guanine, cytosine
deoxyribose, phosphate, nitrogen base

Explanation:

• Question 1: mRNA (messenger RNA) carries genetic information from DNA to ribosomes for protein synthesis. tRNA (transfer RNA) brings amino acids to the ribosomes during translation. rRNA (ribosomal RNA) is a major component of ribosomes. nRNA is not a recognized type of RNA.
• Question 2: RNA is composed of ribose (a sugar), phosphate groups, and nitrogen - containing bases (adenine, guanine, cytosine, and uracil). Thymine is found in DNA, not RNA. Deoxyribose is the sugar in DNA, not RNA.

Answer:

• Question 1: C. nRNA
• Question 2: A. ribose, phosphate, nitrogen base
