DNA nucleotides 'code' for RNA copies of the DNA strand, but the true 'coding' of nucleotides happen in the ribosome where amino acids are matched to the RNA nucleotides.
Nucleotides in DNA are only are present to store genetic data. When a particular gene needs to be used or a protein needs to be made, a RNA copy of the DNA will be made, using the slightly different RNA nucleotides (adenine, uracil, cytosine and guanine). This copy then leaves the nucleus and travels to the ribosome, where the RNA nucleotides are used to assemble amino acids into proteins. Each amino acid matches up to a three-nucleotide sequence.
What else can I help you with?
What three basic molecules are nucleotides composed of?
A phosphate group, a sugar and a nitrogenous base
How do nucleotides in the RNA molecule code for various amino acids How many nucleotides code for one amino acid?
Each nucleotide is made up of an organic base, a pentose sugar and a phosphate. Nucleotides can be arranged in various different orders and that order dictates which amino acid it codes for, three amino acids code for one nucleotide. Is this enough detail?
How many nucleotides of DNA code for the production of human growth hormone?
576, because there are 191 amino acids in human growth hormone. 191x3= 573, but then you add three to account for the nucleotides that act as a stop codon.
What do you call a 3 letter word on a mRNA molecule?
The three-base sequence on a tRNA molecule is known as an anti-codon. This matches up with the codon (another 3-base code) on the mRNA to ensure that the correct amino acid is added to the chain (protein) being created.
The insertion of how many nucleotides into a genetic sequence does less damage to the code than the insertion of other numbers of nucleotides?
3 cause 3 nts corresponding to an amino acid so it wont effect all the following code after insertion
What is a group of three nucleotides called?
This arrangement is called a codon.In DNA and RNA a group of three nucleotides in a row is called a codon. In tRNA a group of three nucleotides is called an anticodon.
What is the term for a sequence of three nucleotides that code for an amino acid in DNA?
The term for a sequence of three nucleotides that code for an amino acid in DNA is called a codon.
How many nucleotides are required to code for one amino acid?
Three nucleotides are required to code for one amino acid.
How many nucleotides are in a codon?
A three-nucleotide sequence makes up a codon.
What three basic molecules are nucleotides composed of?
A phosphate group, a sugar and a nitrogenous base
How many nucleotides are required to encode one amino acid?
A codon, or a 3-base code is required to code for one amino acid.
What is the number of nucleotides found in a protein?
None! The reason is: there are no nucleotides in proteins. Nucleotides are the monomers (building blocks) of nucleic acids. The monomers of proteins are amino acids. The relationship between nucleotides and amino acids is the genetic code. In brief, the genetic code works like this: within a region of DNA that codes for a polypeptide chain (from which a protein will be made) a group of three adjacent nucleotides code for one amino acid.
How many nucleotides are necessary to code for a polypeptide that is 200 amino acids long?
A minimum of 600 nucleotides is necessary to code for a polypeptide that is 200 amino acids long because each amino acid is coded for by a sequence of three nucleotides in mRNA. This is due to the genetic code being triplet, where every three nucleotides represent one amino acid.
What are the three nucleotides that together specify one amino acid?
TRIPLET CODE
A three letter code word made up of 3 nucleotides?
pee
What are three nucleotides that together specify one amino acid?
TRIPLET CODE
Why is the DNA code referred to as a triplet code?
Because for the purpose of translation into aminoacids, each codon is three nucleotides long. In other words peptides which are the building blocks of proteins get made by translating three nucleotides at a time.
