Hey there!
The sides of DNA have rails, or the sides of them that keep them together- and what's amazing is you can't even see it.
They're made of sugar (deoxyribose) and phosphate molecules. They alternate, so sugar, phosphate and so on.
Hope this helps!
A mutation in which the promoter region would result in a reduction in transcription level is option(d)i.e,TATA, GC and CAAT.
A mutation in biology is an adjustment to the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA. DNA or RNA can be found in the viral genome.
Base substitutions, deletions, and insertions are the three different forms of DNA mutations. Point mutations are single-base substitutions; for example, the sickle-cell disease point mutation Glu -----> Val. There are two types of point mutations, the most prevalent of which are. Because it generates a new DNA sequence for a particular gene, the mutation is crucial in the initial stage of evolution because it results in the creation of a new allele. Through intragenic recombination, recombination can also produce a new DNA sequence (a new allele) for a particular gene.
The complete question is:

A. TATA
B. CAAT
C. silencer
