A gene can be defined as a region of DNA that controls a hereditary characteristic. It usually corresponds to a sequence used in the production of a specific protein or RNA.
It also carries biological information
A codon is a sequence of three nitrogenous bases in the messenger RNA sequence that are specific for one amino acid. Molecule (4) represents messenger RNA.

Many RNA molecules from eukaryotic genes have sections called?
if i understand your question right, polymerase is my guess
How many start and stop codons are there?
There are 2 stop codons and 2 start codons
How many protein-coding codons are there?
61 codons specify the amino acids used in proteins and 3 codons (stop codons) signal termination of growth of the polypeptide chain...so 64 total
Which type of RNA contains the codon?
Messenger RNA, or mRNA contains the codons. tRNA (transfer RNA) contains the anti-codons which bond to the codons of the mRNA. Amino acids are attached to the tRNA and form polypeptides based on the codons on the mRNA.
What 3 codons do not carry amino acids?
There are three codons that do not code for any amino acids: the stop codons. These are TAG, TAA, and TGA (in DNA, not RNA).

What in a gene determines a protein's composition?
A gene is made up of triplets of nucleotides called codons. Each codon translates for a a specific amino acid. Some codons don't translate for an amino acid; they are called stop codons or non-sense codons. When m-RNA transcribes the codon triplets and carry them to t-RNA, each amino acid is assembled by r-RNA in the order speicifed in the gene. Thus, the sequence of the codons in the genes is responsible for the sequence of proteins.
What is the difference between DNA and genes in the human body?
If DNA were a book, Genes would be a page in that book. DNA is a huge double stranded helix containing 4 different kinds of base pairs (AGCT). Portions of the DNA code for certain genes. This coding area (this is a very simplistic explanation) is divided into sections of three base pairs called codons. If a gene is a page in the book, a codon is a word on the page. These codons call for a certain amino acid to be placed into a protein. These codons tell other machinery in the cell how to build proteins. The human DNA is about 3 x 108 base pairs in length. It codes for about 25-30K genes. Only about 1.5% of the DNA actually codes for genes. The rest of it consists of introns (non-coding parts of genes) and a bunch of evolutionary useless junk along with parts that code for non-protein genes such as tRNA, etc.
How is it that you have at least two genes for each trait?
I think there are two possibilities 1. A gene is the contiguious series of codons ,nothing but series of triplet codons. So as we know that an aminoacid coded by more than one codon(except Methionine and tryptophan) atleast two codon codes for each amino acids. So a trait that is in the sense of a polypeptide which made by joinig by series of aminoacids which may be coded by different codons. 2. Due to trans splicing as here two different genes are involved in synthesis of a single polypetide.
What characteristics do chromosomes and genes share?
The cell's nuclear genome is contained within the genes that are located inside of the chromosomes. Chromosomes are thread like structures and are located inside of the nucleus in animal and plant cells.
How many start and stop codons are there?
There are 2 stop codons and 2 start codons

How many codons are in aaaugcucguaa?
There are four codons in AAA UGC UCG UAA. A codon is a sequence made of three nitrogenous bases. Codons have particular features, making it possible for them to be start codons, stop codons, introns, or exons.
How do nucleotides provide nucleic acid's with specific codes?
Nucleotides are merely the building blocks of nucleic acids like DNA and RNA. The specific order of these nucleotides are read in triplet form (AAC, ATA, etc.) as codons (which code for amino acids), and the combinations of these codons make up genes (which code for proteins).

Do DNA have codons?
Yes, DNA has codons. Codons are three nucleotides of DNA which code for a single amino acid.
Trna has codons or anticodons?
anti-codons for sure!
