Why do promoters need to be transferred along with desired genes in gene technology?
to ensure the genes are identical
What are coiled strands genetic material called?
genes or dna
What can cause genetic variation?
genes are kept in chromosomes, there is this thing called meiosis which is when the chromosomes/genes get split in half, one from both parents that way it equals the normal amount of genes later. the genes have tons of ways to mix and match around while getting split apart and then ending up in the same place.
Can science create the perfect human being?
Yes, science can create human being in lab, but no one is assured about this human life whether he/she be a perfect or not. The answer to question is depend on two things. As for normal human being the presence of genes and expression of genes. Presence of gene is regulated by nature and expression is regulated by nurture. In the same way, human being can create in lab. Science has all the tools and expertise for it. Science has created "Dolly" so it can create human also. People always have to train to be the best at something. No one is born excellent. Some are born closer to and have an easier time acquiring skill, but unless a person is physically limited
What is a genetic map?
Genetic map is a graphic representation of a linkage group in the form of line which shows by points the sequence of the genes and the relative distances between the genes it contains. Genetic map is called a linkage map, or chromosome map.
What turns off transcription by binding to the operator?
A repressor protein turns off transcription by binding to the operator region. By binding to the operator, the repressor prevents the RNA polymerase from binding to the promoter region and initiating transcription. This prevents the expression of the gene or genes downstream of the operator.
The transcription and translation of genes into proteins is called?
encoding.
What controls the transcription of prokaryotic genes?
The operon often controls the transcription of prokaryote genes.
What would occur if the repressor of an inducible operon were mutated so it could not bind the operator?
It would result in the continuous transcription of the operon's genes.
What is the operon hypothesis and discuss how it explains the control of?
control of messenger RNA production? An operon is made up of a promoter, structural genes, and the operator. The operator is basically the on-off switch for DNA polymerase. Transcription relies on the cell's regulator, which codes for a repressor that bind to the operator. When the repressor binds to the operator, the promoter is blocked. Thus, preventing transcription to occur. However, an inducer can activate or deactivate the repressor. When deactivated, RNA polymerase can bind to the DNA molecule to begin transcription.
Is operon the sequence of bases on a gene that does not code for protein?
operon is a group of genes regulated by a single promoter and operator. . . generally all the genes (structural genes of a particular operon) regulate a specific metabolic pathway. . (eg : lac operon in bacteria; where 3 genes are regulated by a single promoter sequece which help in the catabolism of lactose). . . if you have any doubts mail me at vegi.chaitanya@gmial.com
In the central theory of genes expression what is the process of making mrna from the code in DNA called?
A+LS= Transcription
An operon is composed of?
An operon is a group of genes that operate together.Operon- a functioning unit of genomic DNA containing a cluster of genes under the control of a single regulatory signal or promoter.Operons are clusters of genes consisting of one operator and promoter. There are a lac operon, which is responsible for metabolism of glucose. And there is also the Trp operon, which is responsible for synthesising tryptophan.
The operon segment composed of the gene that codes for a protein repressor is called the?
The operon segment composed of the gene that codes for a protein repressor is called the regulatory gene. This gene produces the repressor protein that can bind to the operator region of the operon, preventing transcription of the structural genes when the repressor is bound.
Are hox genes regulated by operons?
No
A lac repressor turns off the lac genes by binding to?
When the lac repressor binds to the O region, RNA polymerase is prevented from beginning the process of transcription. In effect, the binding of the repressor protein turns the operon "off" by preventing the transcription of its genes. (Prentice Hall Biology Book .....Chapter 12 page 310)
Which is true of transcription factors?
They control which genes are expressed.
