Explanation / Answer

an integral part of the structure and function of ribosomes-

Answer- rRNA, mRNA and tRNA,

Ribosomal RNA (rRNA) associates with the set of proteins to form ribosomes.

It forms a complex structure, which physically move along a mRNA molecule which catalyze the assembly of amino acids into protein chains. They also bind tRNAs and other accessory molecules necessary for protein synthesis

carries a sequence encoding a polypeptide-

Answer- mRNA. tRNA

The mRNA specifies, in the triplet code and amino acid sequence of proteins.  tRNA binds it and move it to the developing end of apolypeptide chain if the next code word on mRNA calls for it.

decodes the codon of a transcrip-

Answer- mRNA and tRNA

first codon of a messenger RNA (mRNA)transcript translated by a ribosome. This starting codon always codes for methionine in eukaryotes and a modified Met (fMet) in prokaryotes. The most common start codon is AUG.  At the time of correlation between codon decoding the tRNA levels is significant for endogenous transcripts in all analyzed organisms.

prevents an mRNA from being translated-

Answer- mRNA and tRNA

In translated RNA molecules every one specific amino acid and for a particular triplet of nucleotides in messenger RNA (mRNA) called a codon. The family of tRNA molecules validate the codons in a mRNA molecule to betranslated into the sequence of amino acids in the protein.
