What is a set of prokaryotic genes that are regulated and transcribed as a unit?
A set of prokaryotic genes that are regulated and transcribed as a unit is called an operon. In prokaryotes, operons consist of multiple genes that are transcribed together into a single mRNA molecule under the control of a single promoter. This allows for coordinated expression of genes involved in related functions.
What gene is always expressed?
Dominant genes will always be expressed however recessive genes would need to be inherited from both parents
If two chromosomes have the same genes for the same trait they are said to be?
Genes on the same chromosome are said to be linked
Are the fathers genes always the dominant genes?
No, the father's genes are not always dominant. Inheritance patterns can vary depending on the specific genes and traits being considered. Some traits may be dominant if they are expressed over recessive genes, while other traits may exhibit co-dominance or incomplete dominance.
Can a individual carry a gene that is not expressed?
not usually, most books fit into the normal genres: mystery, fiction, nonfiction, adventure etc. I believe this person is referring to "genes," not "genres." To answer the question, then: yes, you can have genes that are not expressed. Recessive genes, for example, will not be expressed in heterozygous individuals; they will only be expressed in homozygous recessive individuals. For example; if you have the genotype Aa, the recessive gene - "a" - will not be expressed because the genotype contains a dominant allele, and the dominant allele will always be the one expressed. The only way that the "a" allele will be expressed is, again, if you are homozygous for that recessive gene (your genotype would be aa).
What is the differencs between dominant and recessive?
Dominant genes are genes that are expressed more readily than recessive genes, i.e. if you had a genotype that was AaBb, A being for brown hair, a for blonde hair, B for brown eyes, b for blue, you would have brown hair and brown eyes as the genes for those phenotypes are dominant. For recessive genes to be expressed in the phenotype the gamete needs to have recessive genes for both "slots", e.g. AA for blonde hair to be expressed or bb for blue eyes to be expressed. Edd

What is the extract of RNA?
RNA is the expressed form of a gene (which is DNA encoded). By isolating RNA, it is possible to determine which genes were being expressed and to what relative (or even absolute) level.
How do genes make a phenotype?
They are expressed.
Which genes are dominant and which are recessive?
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.
What genes are expressed even when present on only one chromosome?
dominant genes
What molecules are genes expressed through?
aids
An expressed gene is one that?
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.
Are Genes present in heterochromatin readily expressed?
No. Heterochromatic regions of DNA are not readily expressed as they are densely packaged. Some of these regions do not code for genes at all.
What gene is always expressed?
Dominant genes will always be expressed however recessive genes would need to be inherited from both parents
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
If two chromosomes have the same genes for the same trait they are said to be?
Genes on the same chromosome are said to be linked
