This happens in the process of protein synthesis.

and this would result in synthesis of an very different sequence of amino acids. Errors in the sequence of amino acids can, in fact, result from mutations, as described below.

also dictates where termination of RNA synthesis ..

 Protein Synthesis is the process whereby DNA codes for the production of essential proteins.

What Is the Role of DNA in Protein Synthesis

There are twenty amino acids to choose from for protein synthesis, and a total of 64 triplet codons (four bases in triplet sequence = 4x4x4 combinations).

To understand the role of DNA in protein synthesis, ..

The use of RNAs as scaffolds for biomedical applications has several advantages compared with other existing nanomaterials. These include (i) programmability, (ii) precise control over folding and self-assembly, (iii) natural functionalities as exemplified by ribozymes, riboswitches, RNAi, editing, splicing, and inherent translation and transcription control mechanisms, (iv) biocompatibility, (v) relatively low immune response, and (vi) relatively low cost and ease of production. We have tapped into several of these properties and functionalities to construct RNA-based functional nanoparticles (RNA NPs). In several cases, the structural core and the functional components of the NPs are inherent in the same construct. This permits control over the spatial disposition of the components, intracellular availability, and precise stoichiometry.

There are many thousands of enzymes that participate in synthesis and metabolism.

The synthesis usually requires ..

The sequence of bases in DNA can be thought of as the "letters" that provide the basis for the genetic code for all of the proteins synthesized by our bodies, and these, in turn, provide the basis for the structure of all of our cells, all of our enzymes, and all of our inherited traits and characteristics. As noted above, the genetic code is contained in chromosomes which are gigantic molecules of DNA complexed with proteins and wound into a compact structure. Humans have 23 pairs of chromosomes, which carry our entire genome. In eukaryotes chromosomes are located in the cell nucleus, but prokaryotes (bacteria) have a more primitive cellular structure, and they do not have a true nucleus. Instead, the single bacterial chromosome is in the cytoplasm in an area sometimes referred to as the "nucleoid." The production of cellular proteins requires two major processes.

Like DNA, RNA is assembled as a chain of nucleotides, ..

This publication represents the construction of the largest synthetic molecule of a defined structure; the genome is almost double the size of the previous Mycoplasma genitalium synthesis. With this successful proof of principle, the group will now work on creating a minimal genome, which has been a goal since 1995. They will do this by whittling away at the synthetic genome and repeating transplantation experiments until no more genes can be disrupted and the genome is as small as possible. This minimal cell will be a platform for analyzing the function of every essential gene in a cell.

The history and mysteries of DNA continue to fascinate biologists and chemists alike.

These include the enzyme used for DNA synthesis…

As noted earlier HIV is a retrovirus consisting of a single strand of RNA inside a protein coat. When HIV enters a CD4 lymphocyte, it sheds its protein coat and uses a viral enzyme called reverse trancriptase to create a segment of DNA using the viral RNA as a template. This double-stranded DNA version o HIV then gets incorporated into the DNA of the infected host cell, and this process is called "reverse transcription." This has important consequences for the development of drug resistance by HIV because of several key characteristics of HIV:

Protein synthesis is a two-part process that involves a second type of nucleic acid along with DNA.

By complementary we mean that the base sequence on mRNA has bases that are the complementary pairs of those on DNA. guanine (G) dictates the insertion of its complement, cytosine (C), and cytosine dictates the insertion of guanine (G); thymine (T) dictates insertion of adenine (A) on mRNA and adenine dictates the insertion of uracil (U). [Note that RNA uses uracil in place of thymine.] Once the strand of mRNA has been created, it leaves the nucleus through pores in the nuclear membrane. The video below gives a fairly detailed picture of the process of transcription. .
