The D.N.A. molecule is a double helix. This means that it resembles a ladder that is twisted. The sides of the ladder consist of sugar and phosphate groups. In the center of the ladder are complementary base pairs. Adenine pairs with Thymine, Cytosine with Guanine. When the Hydrogen bonds holding these base pairs together are overcome, either strand of DNA can serve as a template for transcription. During transcription, messenger RNA also present in the nucleus will join to its complementary DNA base on the strand. For instance, if the DNA strands reads, A-T-C-G, the complementary RNA transcription will read U-A-G-C. Remember that RNA does not have the base Thymine(T), so in a pairing with A on the DNA strand, you must substitute the base Uracil(U). Because both sides of the DNA strand can serve as a template, it can easily be transcribed by RNA. Free nucleotides will be attracted to the complementary base and the message will be transcribed by the messenger RNA.

Explain how the structure of DNA enables the molecule to be easily transcribed. Why is this important for genetic information?

 Each DNA molecule consists of two chains of nucleotides that connect to one another like a ladder.  Then, the whole molecule is twisted to form a double helix.  The connections between the two strands are formed between the nucleotides (A, T, C, and G).   A and T always bond to one another, as do C and G.

During transcription, the two chains are "unzipped" or separated to allow mRNA to form.  Transcription happens when the four bases of RNA (A, U, C, and G) bond to their DNA counterparts.  This works exactly the same as it does between the two strands of DNA.  The only difference is that since RNA does not have the T base, it uses U instead.  

The reason that the ease and accuracy of this process is so important to genetic information is that without accurate copies of the DNA, proteins would either be improperly assembled or not at all. No organism could survive without the proper proteins.

Explain how the structure of DNA enables the molecule to be easily transcribed. Why is this important for genetic information.I need a short answer to sum this up

D.N.A. consists of a double helix. One can think of a ladder, which has two sides, with steps in between. Since the molecule has two sides, each side is the complement of the other and can function as a template for transcription(copying)by messenger R.N.A. D.N.A. remains in the nucleus, however, mRNA can transcribe it and take the message to the ribosomes for translation. Since D.N.A. only has four bases, adenine, guanine, cytosine and thymine, and they pair according to the following rules, A pairs with T and C pairs with G, then, only the complementary R.N.A. base will copy the D.N.A. instruction. For example, if the D.N.A. code reads A-T-G-C, the complementary R.N.A. that is transcribed will read  U-A-C-G. *Remember that R.N.A. doesn't have the base thymine, so substitute uracil instead when transcription occurs.
