Why do both strands of DNA not act as a template for RNA synthesis?

Why do both strands of DNA not act as a template for RNA synthesis?

(a)(i)If both strands act as a template, they would code for RNA molecule with different sequence in turn, they code for proteins. Second, the two RNA molecules if produced simultaneously would be complementary to each other. Hence would form a double stranded RNA.

Is the template strand is the strand of DNA used for RNA synthesis?

One strand, the template strand, serves as a template for synthesis of a complementary RNA transcript. The other strand, the coding strand, is identical to the RNA transcript in sequence, except that it has uracil (U) bases in place of thymine (T) bases.

Does RNA act as a template for DNA synthesis?

RNA can act as a template for DNA synthesis in the reverse transcription of retroviruses and retrotransposons and in the elongation of telomeres. An indirect role for RNA in DNA repair, following reverse transcription and formation of a complementary DNA, has been observed in the non-homologous joining of DSB ends.

Why is RNA the template for protein synthesis instead of DNA?

Messenger RNA(mRNA), which carries the genetic information from DNA and is used as a template for protein synthesis. RNA differs from DNA in that it is single stranded, contains Uracil instead of Thymine and ribose instead of deoxyribose, and has different functions.

Can both strands of DNA act as template?

During DNA replication, both strands of the double helix act as templates for the formation of new DNA molecules. Copying occurs at a localized region called the replication fork, which is a Y shaped structure where new DNA strands are synthesized by a multi-enzyme complex.

What would happen if both the strands of DNA act as templates for transcription?

If both strands act as a template, they would code for RNA with different sequence.

What would happen if both strands of the DNA act as template for transcription?

What is the function of template RNA during protein synthesis?

Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell’s ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein …

Why are base sequences of mRNA and the DNA non template strand not identical?

If mRNA is complementary to the DNA template strand and the DNA template stand is complementary to the DNA non-template strand, why are base sequences of mRNA and the DNA non-template strand not identical? No, they cannot be identical because the T nucleotide in RNA is replaced with U nucleotide in DNA.

What would happen if during transcription the DNA strands act as templates?

In transcription, a portion of the double-stranded DNA template gives rise to a single-stranded RNA molecule. Often, however, transcription of an RNA molecule is followed by a translation step, which ultimately results in the production of a protein molecule.

What is the difference between the template and Nontemplate strand of DNA?

The template strand is the one that RNA polymerase uses as the basis to build the RNA. This strand is also called the non-coding strand or the antisense strand. The non-template strand has the identical sequence of the RNA (except for the substituion of U for T).
