Codons are a series of three of the 4 nucelotides (bases) that call for the creation of one of 20 amino acids...or start or stop protein synthesis. Some amino acids have only one codon others have several.
A C T G (U in RNA)
ATC starts protein synthesis for example

Given a chunk of DNA sequences how do you find out if it contains a gene?
In order to find a gene jsut look for a start codon near a promoter and then look for a stop codon in the sequence everything between the start and the stop codon is a gene
What is first located on a gene?
A promoter <--- Gradpoint/NovaNet A promoter is located at the beginning of a gene. A promoter functions by facilitating transcription of that gene
Is a segment of DNA that codes for a specific protein or characteristic.?
gene
What area of the gene is asection of DNA that carries the code used to make a protein?
The correct answer is Exon. This would be a gene. It is in charge of carrying information for the DNA and will have the codes for protein as well.
Why every gene need a start codon?
because without it, ribosome (the proteosynthetic apparatus) would not recognize mRNA produced from this gene

What factor changes the type of protein a gene codes for?
well the gene code itself, each codon (and anti-codon) codes for different proteins
What molecule contain anticodons?
The tRNA gene sequence is the anti-codon while mRNA is the codon sequence.
In a eukaryote an is a segment of a gene that codes for a protein?
codon.
What term refers to each chemical verision of gene?
"codon"
What is the name of the chemical substance that contains the anticodon?
The tRNA gene sequence is the anti-codon while mRNA is the codon sequence.

gene

Section of DNA within a gene that do not encode part of the protein that the gene produces are called?
Introns (the stuff between the exons), and UTR (Untranslated region, the stuff before the start codon, and after the stop codon).
Why every gene need a start codon?
because without it, ribosome (the proteosynthetic apparatus) would not recognize mRNA produced from this gene
What is each nucleotide triplet in mrna that specifies a specific amino acid called?
im pretty sure its a codon
