what is the meaning of the gene expression?

En Español. Gene expression is the process by which the information encoded in a gene is used to direct the assembly of a protein molecule. The cell reads the sequence of the gene in groups of three bases.

In most cases, both alleles of a gene are transcribed; this is known as bi-allelic expression. However, a minority of genes show monoallelic expression. In these cases, only one allele of a gene is expressed.

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.

Gene regulation is a label for the cellular processes that control the rate and manner of gene expression. ... Regulating the processing of RNA molecules, including alternative splicing to produce more than one protein product from a single gene. Regulating the stability of mRNA molecules.

A gene is a portion of DNA that determines a certain trait. An allele is a specific form of a gene. Genes are responsible for the expression of traits. Alleles are responsible for the variations in which a given trait can be expressed.

Gene. A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene. ... Chromosomes occur in pairs so organisms have two alleles for each gene — one allele in each chromosome in the pair.

Gene expression is the process by which the genetic code - the nucleotide sequence - of a gene is used to direct protein synthesis and produce the structures of the cell. Genes that code for amino acid sequences are known as 'structural genes'.

A gene is a section of a long molecule called deoxyribonucleic acid (DNA), or—in some viruses—a similar molecule called ribonucleic acid (RNA). DNA and RNA are made of building blocks called nucleotides. Each nucleotide is built around one of the four different subunits, called bases.

➔ mRNA is the transcript of particular region of DNA, generally protein coding region and not of the whole DNA. It also does not contain sequences of exons from DNA. Thus mRNA is shorter than DNA.

Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).

A gene is the section of DNA required to produce one protein. Genes are typically hundreds or thousands of base pairs in length because they code for proteins made of hundreds or thousands of amino acids. Most genes contain the information needed to make functional molecules called proteins.

Answer and Explanation: The final product of gene expression is protein. When genes are "expressed" they are transcribed to mRNA and translated to protein.

The gene has same status in genetics as the atom has in chemistry. A gene is a segment in DNA that transfers to the offspring and carries some characteristics of parent to transfer into offspring.

A gene is a segment of DNA that can be copied to make RNA. The nucleotide sequence in RNA is translated into the amino acid sequence of a protein. Proteins are the main determinants of the basic structural and physiological properties of an organism. The characteristics of a species are encoded by its genes.

Prokaryotic gene expression (both transcription and translation) occurs within the cytoplasm of a cell due to the lack of a defined nucleus; thus, the DNA is freely located within the cytoplasm. Eukaryotic gene expression occurs in both the nucleus (transcription) and cytoplasm (translation).
