Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The mRNA has bases similar to ____ strand of DNA
A
anti sense
B
sense
C
non coding
D
template
Explanation: 

Detailed explanation-1: -The upper strand of DNA is the “mRNA-like” strand. The lower strand is the strand that is complementary to the mRNA. The-35 region (TTGACA) and-10 region (TATATT) of the promoter sequence and the transcriptional start site (the A) is indicated on the coding strand.

Detailed explanation-2: -Transcription: DNA to mRNA RNA is a molecule that is chemically similar to DNA, and also contains repeating nucleotide subunits. However, the “bases” of RNA differ from those of DNA in that thymine (T) is replaced by uracil (U) in RNA.

Detailed explanation-3: -Antisense In a cell, antisense DNA serves as the template for producing messenger RNA (mRNA), which directs the synthesis of a protein.

Detailed explanation-4: -And mRNA is actually the translated form of DNA that the machinery can recognize and use to assemble amino acids into proteins. So this is really a fundamental link between what we think of as being the code of life and the actual cell being able to construct a living organism.
