Where is the beta globin gene?
The beta globin gene is located on chromosome 11
Why is sickle cell anemia beneficial in some regions but harmful in others?
Depends if the population contains the beta-globin gene. Certain African populations do not contact the beta-globin gene, therefore are resistant to malaria but prone to sickle cell anaemia
Why is a specific region of chromosome 11 referred to as the globin gene cluster?
Due to its relation with formation of globin.
How many copies of a recessive gene does it take to overpower a dominant gene?
It takes 8 copies of a recessive gene to overpeower dominant gene
A transgenic organism that has extra copies of a gene produces more of RNA the that is coded for by the gene?
A transgenic organism that has extra copies of a gene produces more of the DNA that is coded for by that gene
Where is the beta globin gene?
The beta globin gene is located on chromosome 11
What chromosome holds the gene for beta globin?
Chromosome 11

Is sickle cell anemia an autoimmune disease?
Sickle Cell Anemia is Autosomal Recessive. It arises from a mutation on the beta-globin gene of chromosome 11. Because Sickle Cell Anemia is an example of incomplete dominance, a person has the disease if they have two mutated beta-globin genes but only has the trait (is a carrier) if they have only one mutated beta-globin gene.

Due to its relation with formation of globin.
My husband and I are Beta thalassemia minors and undergone Mutation analysis in beta globin gene. sequencing report is also awaited. please advice us on our chances of having a baby in this case?

What is gene cloning?
The production of multiple copies of a single gene.
How many copies of each gene do you have?
Humans typically have two copies of each gene, one inherited from each parent. This pairing of genes allows for genetic diversity and a variety of possible gene combinations. Some genes may have multiple copies or variations, but in general, humans have two copies of most genes.
What is a technique where bad copies of genes are replaced with good copies called?
gene therapy
Name a disease which results from a genetic effect and explain how the genetic defect can bring about to this disease?
As there are many diseses but the most common is sickle cell anaemia. this can be transmitted from parents to offsprings when both the partners are carrier for this disese. this disese is caused due to mutation in the gene i.e. it is caused by the substitution of glutamic acid(glu) by valine(val) at sixth position of the beta globin chain of haemoglobin molecule. the substitution of acid results due to single base substitution at the sixth codon of beta globin gene from GAG to GUG. the mutant haemoglobin molecule undergoes polymerisaTION UNDER LOW OXYGEN TENSION CAUSING THE CHANGE IN THE SHAPE OF RBC FROM BICONCAVE DISC TO ELONGATED SICKLE LIKE STRUCTURE.
