Question

How do you think a cell will be if it will directly use DNA in protein synthesis without Any intermediate molecules such as mRNA?

Answer 1

Answer:

During transcription, an enzyme known as RNA polymerase binds to promoters of the DNA, which are specific sequences of nucleotides that are present in many locations in the DNA molecule. They represent the starting point for transcription. RNA polymerase then breaks down hydrogen bonds between two strands of the DNA and attaches on one of them. A DNA strand is used as a template for a new RNA molecule. In this way, pre-mRNA is made, which becomes mRNA after the introns are removed. A mRNA molecule enters the ribosomes, where transfer RNA attaches to it. A mRNA molecule is built of codons, which are sequences of three nucleotides in a row, which determinate an amino acid. The starting point in the translation process is AUG codon. Based on these codons, tRNA with adequate anticodons adds amino acids in order to make polypeptide molecules. The translation process is completed when the stop codon is reached.

Answer 2

QUESTION:-

How do you think a cell will be if it will directly use DNA in protein synthesis without Any intermediate molecules such as mRNA?

ANSWER:-

• It is extensive, according to the primary principle of the biology of molecules, that in the biological operation information travels from DNA that is transmitted into mRNA, mRNA is transmitted into protein by certain enzymes like RNA polymerase and peptidyl transferase, with respect.

• This is the two-step procedure that is transcription and translation through which the information in genes flows into proteins:
• DNA → mRNA → protein

• Direct use of DNA in protein synthesis without any intermediate molecules such as mRNA cannot be converted because there are enzymes that are available to interpret DNA directly into protein. First, DNA is transcribed into mRNA, and then mRNA is translated into a protein with the support of certain enzyme apparatus such as ribosomes, tRNA, amino acids and peptidyl transferase enzymes.
