Which chromosomes carries the fewest numbers of genes?
The y chromosome, which only contains a few hundred genes.
Where are your genes located in a cell?
Genes are coded into the the DNA in the nucleus of a cell.
What is the role of environmental factors in cell differentiation?
Environment factors in cell differentiation influence the expression of genes. A few examples of environmental factors are chemicals, drugs, and temperature.
What are essential genes and non essential genes?
Essential genes are genes that are indispensable to support cellular life. These genes constitute a minimal gene set required for a living cell. Nonessential genes are the opposite. The cell can still live without them.
What is unexpressed genes?
Genes are cells that decompose in a plant cell.
Why does it take only a few homeotic genes to control the development of a eukaryote?
Different genes are turned on or off in the different cell types as a result of specialization
Which chromosomes carries the fewest numbers of genes?
The y chromosome, which only contains a few hundred genes.
What is the gamete that contains genes contributed only by the father?
the sperm cell
Where are your genes located in a cell?
Genes are coded into the the DNA in the nucleus of a cell.
How does DNA technology transfer bacteria genes from cell to cell?
DNA technology will transfer bacteria genes from cell to cell.
What are the alleles of a gene?
That depends on the gene: some genes have only a few alleles, some genes have hundreds or even thousands of alleles.
What groups get sickle cell disease?
A person can only inherit sickle-cell genes if some of their ancestors came from certain regions in Africa where the inhabitants carry sickle-cell genes. A person with one sickle-cell gene has sickle-cell trait, a milder problem. If both father and mother pass on sickle-cell genes, the child, with two genes, will have sickle-cell disease.
Why do two nuclei in a divided cell need to be identical?
In a divided cell, the nuclei is identical because it can only reproduce "A sexually" in a sense. Meaning, that if offspring is reproduced, then it must have the genes of the parent cells, but if there is only one parent, then it will have only the exact genes of the single parents, there by being identical.
Genes are found on which part of a cell?
Genes can be found in chromosomes. The cell nucleus of almost every cell contains chromosomes and genes. They contain the DNA and the gene shows as a section of the DNA.
What is the role of environmental factors in cell differentiation?
Environment factors in cell differentiation influence the expression of genes. A few examples of environmental factors are chemicals, drugs, and temperature.
What is unexpressed genes?
Genes are cells that decompose in a plant cell.
What are essential genes and non essential genes?
Essential genes are genes that are indispensable to support cellular life. These genes constitute a minimal gene set required for a living cell. Nonessential genes are the opposite. The cell can still live without them.
