Answer:

D-DNA molecule

Explanation:

The process of copying the sequence of  DNA nucleotide  sequences to the mRNA is called   Transcriptions. It  is the  first stage in gene expression   for protein synthesis, and<u> it involves the unwinding of the DNA double strands  molecules  by enzyme</u><u> </u>DNA Helicase into two  free strands,(by melting the hydrogen bonds between organic  bases), a process   initiated by the binding of enzymes RNA Polymerase to  the promoter sites on the DNA  template; the alignment of the mRNA  nucleotides on the  single DNA template strands in 3'-5  direction; the formation of  hydrogen bonds between the organic bases  of the template DNA  and   that of the messenger RNA single strands,(  and phosphodiesterbonds  within RNA nucleotide ), to form DNA-RNA complex.

The copying is done in  complimentary anti parallel fashion;5'-3' prime. direction.

 The  hydrogen bonds, between the bases  DNA-RNA complexes breaks,and  the releases  the mRNA  which  exists through the nuclear pores.Thus  this <u>leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.</u>

Most organisms can be divided into two categories, namely: prokaryotes and eukaryotes. What is the main difference between these
Inga [223]
Prokaryotes and eukaryotes differ in terms of size, presence of nucleus, presence of golgi apparatus and other features. Prokaryotes are way smaller than their counterparts, and do not have nuclei and golgi apparatus.

Other factors being equal, which sensory stimulus is least likely to lead to sensory adaptation?
valentina_108 [34]
The correct answer is: the wail of a loud car alarm. 
Sensory adaptation is a term that refers to the changes that stimuli can trigger on the sensory receptors. The process involves changes in the receptors' sensitivity and it is believed that all of the senses exhibit this adaptation. In particular, the sense of touch can quickly adapt to hot and cold stimulation, but not when the stimulus is extremely intense (such as too hot or too cold). Also, our olfactory sense presents the characteristic of odour fatigue. A prolonged exposure to a specific smell leads to a temporary inability to sense this smell and this is a type of sensory adaptation. Finally,
our hearing undergoes a sensory adaptation as well, but not when it comes to sudden, unexpected and instantaneous loud noises. That is why the wail of a loud car alarm will be the least likely to cause sensory adaptation.
