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>
The energy of the ecosystem can be best described as option C. The amount of energy entering an ecosystem from the Sun is equal to the amount used by organisms plus the amount lost as heat.
Here’s the answer:

The term <u>Ataxia</u> means the lack of muscle coordination during voluntary movement.
- Poor muscle control that results in awkward voluntary movements is known as ataxia.
- It might make it difficult to move your eyes, speak, or walk steadily. It might also make it hard to coordinate your hands.
- Ataxia is typically caused by injury to the cerebellum, which regulates muscular coordination, or its connections.
- Ataxia is typically brought on by damage to the cerebellum, a region of the brain, although it can also be brought on by injury to the spinal cord or other nerves.
- The spinal cord, which extends the length of the spine and connects the brain to every other part of the body, is a lengthy bundle of nerves.
