Question

Which nucleic acid moves the code for protein synthesis from the nucleus to the ribosomes? dRNA tRNA rRNA mRNA

Answer 1

Answer:

The correct answer would be mRNA (messenger ribonucleic acid).

mRNA is a single stranded nucleic acid transcribed from template strand of DNA (deoxyribo nucleic acid) by the process of transcription.

The nucleotide sequence of mRNA is complementary to the template DNA strand.

It carries this information or nucleotide sequence from nucleus to ribosomes where it is translated into the amino acid sequence of the polypeptide chain.

tRNA (transfer RNA) helps in decoding the codon sequence of the mRNA and translate it into amino acid sequence.

Answer 2

The correct answer is option D, mRNA

Reason -

mRNAs are responsible for carrying the coding sequence for the protein synthesis and are also called as transcripts. After the transcription of DNA to mRNA, the transcripts are converted into amino acids chain with in the ribosome where it folds finally to form the functional protein.  Translation of mRNA begins with the help of tRNA and the rRNA in the ribosome lead to formation of protein
