What is synthesized when a gene is expressed at the molecular level?
The expression of a Gene causes the synthesis of Its associated protein.
Constituents of a gene?
There are three main parts of a gene. First, the promoter includes when and where the gene should be transcribed. Then, the coding sequence contains the instructions for making a protein. Last, the terminator indicates that the coding sequence is over.
If a specific kind of protein is not continually used by a cell the gene for that protein is?
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 )
What is a homologous expression system?
Heterologous Expression systems are tools to find out whether a particular gene produces mRNA and/or protein and whether the protein produced is functional or defective. In these systems, we use the expression vectors in which cDNA of the gene of interest is clonned along with suitable promoter. When this gene is expressed through transcription by the formation of mRNA, then the resultant protein is formed by translation of mRNA.
Why do the introns have to br removed?
Introns are the non-coding parts of the gene. If you didn't remove introns, the wrong protein may be produced because they allow more than one protein to be produced from a single gene.
What is synthesized when a gene is expressed at the molecular level?
The expression of a Gene causes the synthesis of Its associated protein.
What does recessive tell us about gene's expression?
Recessive doesn't really describe the expression of a gene. When a gene is "expressed" a protein is made. Recessive describes what form of the gene is expressed or in other words, which allele. A recessive protein may look different and function differently than a dominant protein. This is oversimplified though because there are many different interactions and mechanisms that determine protein function.
When a gene or genes which code for units which make up a protein are turned on by?
expressed
When a gene or genes which code for units which make up a protein said to be?
expressed
What is putative gene?
a putative gene is a piece of DNA thought to be a gene based on sequence (ex. Open Reading Frame) but either the protein produced or the function of what is thought to be the expressed protein is not known
If a specific kind of protein is not continually used by a cell the gene for that proteins is?
never expressed.
Constituents of a gene?
There are three main parts of a gene. First, the promoter includes when and where the gene should be transcribed. Then, the coding sequence contains the instructions for making a protein. Last, the terminator indicates that the coding sequence is over.
What is the obesity gene that is expressed in fat cells and codes for a hormone-like protein that researchers have identified known as?
The obesity gene that researchers have identified is known as leptin-E100. This was the first fat cell protein to be discovered.
An expressed gene is one that what?
a gene being expressed means it is shown, for example if you have the gene for brown eyes and the gene for blue eyes, only one can be expressed. if you have brown eyes that gene is expressed, if not the blue-eye gene is expressed.
Is an expressed gene turned off?
No. If a gene is expressed, it is turned on.
What happens to a gene for a protein that is not used much in the cell?
Nothing "happens" to it. When a gene is not actively being copied or expressed it is folded up and stored till it is needed again.
If a specific kind of protein is not continually used by a cell the gene for that protein is?
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.
