its genome sequence and blueprint of organisms, the set of instructions explaining its biological traits. The unfolding of these instructions is launched by the transcription of DNA into RNA sequences. Based on the standard model, the majority of RNA sequences stem from protein-coding genes, namely, they’re processed into mRNAs after their export to the cytosol and are translated into certain proteins.

How many genes are there in DNA?
Different species have different numbers of genes. About 1.5% of human DNA is genes - and it is estimated that there are around 23,000 protein-coding genes.
What are the regions of DNA called that code for protein?
The coding regions of many eukaryotic genes are interrupted by non-coding sequences known as INTRONS. They are stretches of DNA whose transcripts are absent from mature mRNA product.
What is the terms refers to a region of a chromosome that has a specifiic function?
The region of chromosome that is generally thought of as the unit of function is the "gene". Genes are composed of both a "coding region"--that sequence that tells the cell's machinery what the protein will be--and a "regulatory" region, which tells the cell when to turn on the coding region to make the protein.
Is a gene the same thing as a chromosome?
No - genes are sections of DNA found on chromosomes that encode for a functional product (like a protein).Chromosomes are compact structures of DNA and proteins.
Describe two reasons why geneticists have reevaluated their traditional view that one gene codes for one polupeptide?
1) Because protein coding accounts for less than 2% of the DNA in human chromosomes. 2) there isn't a clear correspondence between the complexity of an organism and the number of protein-coding genes in its genome.
What are coding segments?
"Coding segments" is the term given to genes, segments of the DNA strand that code for a protein. Much of an organism's genome is non-coding segments, portions that do not have a role in protein synthesis.

Different species have different numbers of genes. About 1.5% of human DNA is genes - and it is estimated that there are around 23,000 protein-coding genes.
Environmental factors affect the coding of genes?
yes it can affect the coding of genes.
What are the parts of the genome control system?
1) Epignetic marks 2) Protein-coding genes 3) Small RNAs
How genes carry inherited information from one generation to another?
its biologically incorrect to give a number of the genes...but through a rough estimate we can say thatthere are almost 20000-25000 protein coding genes
Is most of the DNA is humans coding DNA?
No - only a small part of human DNA is coding DNA. About 3% of DNA is genes. These are the sequences that code for a functional unit (like protein).
What is the relationship between the genes and chromosomes?
There are thousands of genes in a chromosome.
Do chromosomes have the same or different genes?
There are many more genes than chromosomes. The Human Genome Project currently has identified about 20,000 protein-coding genes, while there are only 46 chromosomes in the human genome.
What are the regions of DNA called that code for protein?
The coding regions of many eukaryotic genes are interrupted by non-coding sequences known as INTRONS. They are stretches of DNA whose transcripts are absent from mature mRNA product.
What are genes a part of?
There are three main parts of a gene. First, the promoter includes when and where the gene should be transcribed. Then, the coding sequence contains the instructions for making a protein. Last, the terminator indicates that the coding sequence is over.
