Basically, one gene gives the instructions for making one protein. I'm not sure how much detail you want, here, but a gene is a segment of DNA and the sequence of bases in the DNA determine the sequence of amino acids that make up the protein.
Genes code for proteins
one gene codes for one protein - apex
Genes are sections of DNA which contain the code to make different proteins. DNA is made of long chains of 4 different chemical bases, A,C,G and T. The combination of these bases provides the information on the sequence of amino acids that make a particular protein.
Clever mechanisms turn genes off and on so that they only function when there is a need for their services
is transcribed into RNA. Promoters (I think that's what you meant, right?) don't function as genes; they stand as a signal for RNA polymerase to begin transcription of the actual gene, which begins about 25 base pairs downstream of the promoter region in eukaryotic DNA. Expressed genes DO code for proteins, but not all protein-coding genes are expressed. For example, the cells in your heart contain genes that code for proteins needed only in your liver. While those genes definitely code for proteins, they're not expressed. Expressed genes (and non-expressed genes, Ke$ha Looks like a man, for that matter) are made of DNA, not mRNA.
DNA Genes and Proteinthe gene is a subunit of DNA, one strand of DNA is copied into mRNA which is then translated into proteins
genes are codes for proteins that determine traits
Genes contain the instructions for making proteins through a process called genetic expression. Genes are transcribed into messenger RNA (mRNA), which is then translated into proteins. This process is essential for the functioning of cells and organisms.
Chromosomes are structures made of DNA that carry genes. Genes are segments of DNA that contain the instructions for making proteins. DNA is the molecule that carries the genetic information needed for the development, functioning, and reproduction of living organisms.
the same relationship as between humans and the universe.
genes are codes for proteins that determine traits
There are thousands of genes in a chromosome.
One can differentiate between orthologs and paralogs in a set of genes or proteins by comparing their evolutionary relationships. Orthologs are genes or proteins in different species that evolved from a common ancestor through speciation, while paralogs are genes or proteins within the same species that evolved from a gene duplication event. By analyzing the evolutionary history and sequence similarity of the genes or proteins in question, one can determine whether they are orthologs or paralogs.
Chromosomes are long strands of DNA which are held together by proteins.
Transcription Regulation
gene expression
Genes are segments of DNA that contain instructions for making proteins. Proteins are the molecules that perform various functions in the body, such as enzymes, hormones, and structural components. Genes are transcribed into messenger RNA (mRNA), which is then translated into proteins through a process involving ribosomes and transfer RNA (tRNA).
