No, a baby cannot be born with a CF gene if neither parent has the gene. Cystic fibrosis is an autosomal recessive genetic disorder, meaning both parents must be carriers of the mutated CF gene in order to have a child with the condition.
the gene is never expressed. ^^^^ this guy is a frickin idiot. and this would more of be in the cells/ biology section. What happens is a repressor binds to the operator and turns off the gene so the protein doesn't get made. and when its needed the repressor detaches and the gene is turned back on. ( this all happens on a strand of DNA )
When the repressor protein in not functioning then the gene that that protein was blocking will be "turned on". BTW its not right to cheat, even on study guides ;)
No, not all of an organism's genes are turned on at the same time. Gene expression is tightly regulated in response to different environmental cues, developmental stages, and cellular needs. This regulation allows for specific genes to be turned on or off as needed for the organism's survival and functioning.
a phrase is 3or 4 words in a sentence that describe something.
That's easy! Its a phrase.
No. If a gene is expressed, it is turned on.
Lost in the fun house is a phrase meaning the person keeps getting turned around and running into dead ends. The phrase is based after the popular carnival attraction.
In the U.S. south, I've always heard the phrase as "katty wompus", meaning completely backward, or upside down, or turned around.
The constitutive expression of a gene means that the gene is always turned on and producing its protein, regardless of the cell's environment. On the other hand, conditional expression means that the gene is only turned on in specific conditions or in response to certain signals.
When a gene is turned off or not expressed, it means that the DNA sequence within that gene is not being transcribed into mRNA and translated into protein. This can happen through a variety of mechanisms that regulate gene expression, such as DNA methylation, histone modification, and transcription factor binding.
repressor proteins block the gene physically and prevent transcription from occurring

The phrase "grist for the mill" means material or information that can be used to generate further benefit or advantage. It refers to something that can be turned into a useful or productive outcome.
