Which of the following molecules directly participates in the process of translation?
mRNA, DNA, and rRNA
mRNA, tRNA, DNA, and rRNA
mRNA, tRNA, and rRNA
mRNA, tRNA, and DNA

Answer 1

Answer:

mRNA, tRNA, and rRNA

Explanation:

Translation is the second process of gene expression involving the synthesis of proteins from mRNA strand in the ribosomes. mRNA is the template for the translation process to occur. However, other certain molecules are necessary for the occurrence of translation.

The molecules that directly participates in the process of translation include:

- mRNA, which is transported from the nucleus into the cytoplasm (ribosomes) to be read.

- tRNA, this is a type of RNA present in the ribosomes whose function is to read the codons of the mRNA and carry corresponding amino acids to the peptide chain.

- rRNA, is another type of RNA that makes up the ribosomes and functions in the synthesis of proteins from the amino acids.

Answer 2

mRNA, tRNA, and rRNA directly participate in the process of translation.

• During gene transcription, a specific sequence of DNA called gene is utilized as a template to create a messenger RNA (mRNA).

• This mRNA then travels to the ribosomes where is used to create a protein by a process called translation.

• The ribosome is a ribonucleoprotein complex consisting of proteins and ribosomal RNA (rRNA) sequences.

• The triplets of nucleotides or 'codons' in the mRNA indicate the linear order of amino acids that will be added to the protein.

• The transfer RNAs (tRNAs) are molecules that transport specific amino acids to the ribosomes and pair them via anticodon sequences that match the codon in the mRNA.

In conclusion, mRNA, tRNA, and rRNA directly participate in the process of translation.
