DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of RNA functions as a copy of the genetic code
A
tRNA
B
mRNA
C
rRNA
D
dRNA
Explanation: 

Detailed explanation-1: -Messenger RNA (abbreviated mRNA) is a type of single-stranded RNA involved in protein synthesis. mRNA is made from a DNA template during the process of transcription.

Detailed explanation-2: -Specifically, messenger RNA (mRNA) carries the protein blueprint from a cell’s DNA to its ribosomes, which are the “machines” that drive protein synthesis.

Detailed explanation-3: -Transcription, as related to genomics, is the process of making an RNA copy of a gene’s DNA sequence. This copy, called messenger RNA (mRNA), carries the gene’s protein information encoded in DNA.

Detailed explanation-4: -The majority of genes carried in a cell’s DNA specify the amino acid sequence of proteins; the RNA molecules that are copied from these genes (which ultimately direct the synthesis of proteins) are called messenger RNA (mRNA) molecules.

Detailed explanation-5: -Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.
