Question

question 1
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 nucleotide?
○ ribose, phosphate, nitrogen base
○ thymine, adenine, guanine, cytosine
○ deoxyribose, phosphate, nitrogen base
○ sugar, hydrogen bond, uracil

Explanation:

Question 1

RNA types include mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA). There is no "nRNA" type.

Question 2

An RNA nucleotide consists of ribose (sugar), phosphate group, and nitrogen - base (adenine, guanine, cytosine, or uracil). Thymine is in DNA, deoxyribose is in DNA, and hydrogen bonds are not part of a single nucleotide structure.

Answer:

Question 1

nRNA is NOT a type of RNA.

Question 2

ribose, phosphate, nitrogen base includes all parts of an RNA nucleotide.
