All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences.

All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences.

Cell cycle has been as the defined as cycle in which cell produces, grows and divides. The cell cycle has mainly three steps the first one has G1 phase in which the size of the cell increases, S phase synthesis of DNA takes place and the third step has G2 phase in which all cell ready to divide.

Cell has been defined as the base of the life as it has the structural as well as functional unit of life. Cell has been made up of pre existing cells and the cell contain various part cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.

Therefore, All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences.

Explanation:

Answer:

Interphase is divided into three subphases which are G1 phase, S phase and G2 phase.

Explanation:

During G1 and G2 phases, the cell grows by producing proteins and cytoplasmic organelles. Cell growth and cell differentiation occur. In the S phase, synthesis of DNA occurs. The chromosomes are duplicated and DNA has replicated to form two identical sister chromatids joined together by centromere. During interphase, the chromosomes are not visible but appear as thread-like structures, chromatin. In general. Interphase is the phase where the cell prepares for cell division. It involves synthesis of protein and organelles, growth, replication of DNA, cell differentiation and energy storage.

Cross: true-breeding red-eye fly bred with a true breeding white-eye fly

Parentals)           RR           x       rr

Phenotypes) Red-eyed     White-eyed

Gametes)       R         R           r         r

F1) 4/4 = 100% of the progeny will be heterozygous for the trait expressing     red eyes, Rr

---------------------------------------------------------------------------------------------------------

In Drosophila melanogaster, the fruit fly, the gene for the eye color is X-linked. So in this species:

- X⁺ expresses red eyes ----- > + is the dominant allele for red color

- X⁻ expresses white eyes ----> - is the recessive allele for white color

Option 1: true-breeding red-eyed females and white-eyed male

Parentals)                X⁺ X⁺          x       X⁻Y

Phenotypes) Red-eyed female     White-eyed male

Gametes)           X⁺            X⁺             X⁻         Y

                     X⁻    X⁺X⁻       X⁺X⁻

                     Y      X⁺Y         X⁺Y

F1) 4/4 = 100% of the progeny will express red eyes

    50% of individuals are red-eyed males, X⁺Y

    50% of individuals are red-eyed heterozygous females, X⁺X⁻

Option 2: true-breeding white-eyed females and red-eyed male

Parentals)                X⁻ X⁻         x       X⁺Y

Phenotypes) Red-eyed female     White-eyed male

Organisms whose genetic material has been modified are called Genetically modified organisms. The bacteria can be used for the production of Insulin that can be used by humans.

Genetically modified organisms are altered and modified living things like animals, plants, a microorganisms that are modified by the methods of genetic engineering and recombinant DNA technology.

The genetic material that is modified and inserted in the host for the expression of the gene of interest is called a transgene. The genetically modified gene can be inserted in bacteria, plants and animals.

In the diagram gene for the production of human insulin is inserted in the bacterial DNA so the insulin produced can be used for the treatment of diabetic human patients.

Therefore, option A. bacteria cells can be used for the production of Insulin.

Answer:

Explanation:

The sickle cell allele is recessive. Hence, in order for any child of the couple to have sickle cell anemia, such a child will have to inherit an affected allele each from the two parents. This means that both the father and the mother must have affected alleles in their genotypes. In other words, two sickle cell alleles are required for the abnormality to manifest.

Let us assume that the sickle cell allele is represented by S and the normal allele is represented by A.

Now, it is established that the mother has sickle cell anemia, her genotype would be SS. The father does not have sickle cell, his genotype can either be AA or AS.

Assuming the genotype of the father is AA:

          SS   x   AA

      AS   AS   AS   AS

All the children would be normal in this case.

Assuming that the genotype of the father is AS

           SS    x    AS

      AS   SS   AS   SS

50% of the children would have sickle cell while the remaining 50% would be normal.

Therefore, in order to produce children with sickle cell, the father has to be AS, otherwise, he has to be AA.

The beta globin protein is one of the subunits of hemoglobin, a protein necessary for the oxygen-carrying function of red blood cells. People with the sickle cell mutation in both copies of the HBB gene produce proteins that clump together and lead to changes in the shape and behavior of red blood cells.

A stable atom that emits gamma rays is used in radiation therapy to treat cancer. Thus option C is correct.

Cancer is a disease in which abnormal cell growth occur with the help of uncontrolled cell division and  spread to other parts of the body.  If it is fixed to one specific area of the body called as benign whereas if it spreads over different parts of body called as malignant.

In case of normal cell growth when human cells will grow and multiply to form new cells, when become old it will get damaged; In case of cancer mainly caused by genetic changes that control the way our cells function.

These Genetic changes that cause cancer include errors in cell division, damage of DNA due to harmful substances in the environment like chemicals in tobacco smoke and ultraviolet rays, also inherited from parents.
