Answer:
a.genetic code in the nucleus- DNA
b. main component in a ribosome- rRNA
c. translated with introns removed- mRNA
d. attached to amino acids -tRNA
e. translated including introns- pre-mRNA
Explanation:
a. DNA- is a nucleic acid molecule that acts as a genetic material in the organisms. In eukaryotes, the DNA molecule is present in the nucleus of the cell
.
b. rRNA- is a molecule formed by the transcription but does not undergo translation and is directly involved in the formation of the ribosome structure which provides the site for the protein synthesis.
c. mRNA- is the RNA formed from the DNA by transcription which contains the message for the formation of the protein molecule. The mRNA is formed after the modification like splicing which removes the non-coding sequence.
d. tRNA-transfer RNA is involved in the translation of mRNA as it brings a specific amino acid to the peptide after it recognizes the codon.
e. pre-mRNA- is the mRNA molecule that has not undergone any modification and thus contains the non-coding sequence also.
