What part of a nucleic acid allows it to be used to form a code?
The form of nucleic acid that allows it to be used as a code is DNA. This is because DNA is the genetic code for everyone's genetic make up.
What is the primary function of DNA?
DNA is the genetic material of cells. The major function of DNA is to store and transmit genetic (hereditary) information. It does this by providing a code (the genetic code) for the production of proteins by the cell.
What is the central dogma of molecuar biology?
The central dogma of molecular biology essentially tells hows how proteins (which make up majority of the structure and function of the body) are made from the genetic code. The genetic code, DNA, is transcribed into RNA. RNA is then translated to protein.
What is a codon in biology?
Three-nucleotide sequence on messenger RNA that codes for a single amino acid. :)
What does it mean to say that the genetic code is triplet?
Prior to understanding the details of transcription and translation, geneticists predicted that DNA could encode amino acids only if a code of at least three nucleotides was used. The logic is that the nucleotide code must be able to specify the placement of 20 amino acids. Since there are only four nucleotides, a code of single nucleotides would only represent four amino acids, such that A, C, G and U could be translated to encode amino acids. A doublet code could code for 16 amino acids (4 x 4). A triplet code could make a genetic code for 64 different combinations (4 X 4 X 4) genetic code and provide plenty of information in the DNA molecule to specify the placement of all 20 amino acids. When experiments were performed to crack the genetic code it was found to be a code that was triplet. These three letter codes of nucleotides (AUG, AAA, etc.) are called codons. The genetic code only needed to be cracked once because it is universal (with some rare exceptions). That means all organisms use the same codons to specify the placement of each of the 20 amino acids in protein formation. A codon table can therefore be constructed and any coding region of nucleotides read to determine the amino acid sequence of the protein encoded. A look at the genetic code in the codon table below reveals that the code is redundant meaning many of the amino acids can be coded by four or six possible codons. The amino acid sequence of proteins from all types of organisms is usually determined by sequencing the gene that encodes the protein and then reading the genetic code from the DNA sequence.
What does the four bases of DNA contain?
They're just four chemicals that make up the genetic 'code'.
How does genetic engineering affect a cell's characteristics?
Allows scientists to induce a cell to make needed chemicals.
Which groups of organism use a genetic code to make proteins?
All of them!

What role do ribosomes play in carrying out the genetic instructions?
it can reads the code and make new proteins
What determines the mRNA sequence?
The genetic code is determined by the specific sequence of four nucleotide bases that make up DNA. The bases are guanine, adenine, thymine, and cytosine.
What is the primary function of DNA?
DNA is the genetic material of cells. The major function of DNA is to store and transmit genetic (hereditary) information. It does this by providing a code (the genetic code) for the production of proteins by the cell.
Why can DNA in one organism be used to make the same protein in another organism?
The Genetic Code is Universal.
How do you know if the human being evolved from apes?
Our genetic code make up, is very similar to that if the apes.
