Question

rna
stands for: ribonucleic acid

of strands: _1_

nitrogenous bases: _aucg_, _mrna_, _trna_, _rrna_
3 types: messenger rna, transfer rna, and ribosomal rna
messenger rna
abbreviation: _mnra_
function: copies code from a _ in dna
found in: nucleus and cytoplasm
transfer rna
abbreviation: _
function: brings _ _ to the ribosome according to the code on _
found in: cytoplasm
ribosomal rna
abbreviation: _
function: makes up part of the _
found in: ribosome

Explanation:

Step1: Correct Messenger RNA Abbreviation

Messenger RNA's correct abbreviation is mRNA (not MNRA). So we fill "mRNA" in the abbreviation field.

Step2: Messenger RNA Function

Messenger RNA copies the code from a "gene" in DNA (since genes are segments of DNA that code for proteins, and mRNA transcribes the gene's code).

Step3: Transfer RNA Abbreviation

Transfer RNA's abbreviation is tRNA. Fill "tRNA" here.

Step4: Transfer RNA Function

Transfer RNA brings "amino acids" to the ribosome according to the code on "mRNA" (tRNA has an anticodon that pairs with mRNA's codon, and carries the corresponding amino acid).

Step5: Ribosomal RNA Abbreviation

Ribosomal RNA's abbreviation is rRNA. Fill "rRNA" here.

Step6: Ribosomal RNA Function

Ribosomal RNA makes up part of the "ribosome" (rRNA is a structural component of ribosomes, along with proteins).

Answer:

• Messenger RNA: Abbreviation: $\boldsymbol{\text{mRNA}}$, Function: copies code from a $\boldsymbol{\text{gene}}$ in DNA
• Transfer RNA: Abbreviation: $\boldsymbol{\text{tRNA}}$, Function: brings $\boldsymbol{\text{amino acids}}$ to the ribosome according to the code on $\boldsymbol{\text{mRNA}}$
• Ribosomal RNA: Abbreviation: $\boldsymbol{\text{rRNA}}$, Function: makes up part of the $\boldsymbol{\text{ribosome}}$

(Also, correcting RNA's nitrogenous bases: The nitrogenous bases in RNA are A, U, C, G (Adenine, Uracil, Cytosine, Guanine), and the types of RNA are mRNA, tRNA, rRNA (the earlier fill for nitrogenous bases had a mix-up; the bases are AUCG, and the types are mRNA, tRNA, rRNA). The number of strands for RNA is 1, which is correct.)
