Reading:
Jack and Diane had worked hard to make it through college at the University of Houston. Both had taken out student loans and worked full-time to make it through. The hard work paid off when Jack got his first electrical engineering job at a large computer company in Houston making $35,000 a year. Diane graduated with a degree in child development and started a little daycare center in their new suburban home outside Houston.
Things were going so well that they decided to make an addition to the family, and luckily enough, nine months later, a bouncing baby boy arrived. Danny seemed to be a perfectly healthy baby boy. When Danny started to walk, he fell a lot, as most children do. On one occasion Danny hit his head on the coffee table and cut himself above his right eye. As concerned parents, Jack and Diane took Danny to their local pediatrician to see if he needed stitches.
As they were driving to the doctor, Diane commented that the bleeding would not stop. When the pediatrician began sewing up the eye, he knew that there was more to the cut than just a simple laceration. The doctor asked the concerned parents if Danny was a hemophiliac. To this point, they had never had any reason to suspect that their little boy had any problems with blood clotting. The doctor took some blood and sent it to the lab to be analyzed. Their fears were confirmed--Danny was a hemophiliac.
Hemophilia refers to a group of bleeding disorders in which it takes a long time for the blood to clot. In severe cases, serious bleeding may occur without any cause and internal bleeding may occur anywhere.
Hemophilia is an X-linked recessive characteristic that usually occurs in males. If a mother is a carrier of the recessive gene there is a 25% chance she will have a child who is a hemophiliac. If females are born with hemophilia they are certain to have problems during puberty. To treat this problem, victims are given transfusions of Factor VIII, which is one of the platelet chemicals that healthy people produce to clot blood. The cost of Factor VIII transfusions can run up to $80,000 a year per patient. Luckily for Jack and Diane, they had insurance through his company. The insurance paid 90% of the bills so that left $8,000 to be paid by Jack and Diane. This put a small stress on their marriage. However, they decided to have another child, even though they knew there was a 25% chance their next child could be a hemophiliac also.

Crossing over is a phenomenon that creates genetic diversity during mitosis is the incorrect statement.

What is Meiosis and Mitosis?

Two distinct cell division processes, meiosis and mitosis, are frequently observed in organisms.

While meiosis is a specific type of cell division that occurs in germ cells during the production of gametes and results in the formation of haploid gametes, mitosis is responsible for the growth of organisms.

DNA replication comes after both kinds of cell division.

DNA replication is followed by cell division in mitosis. Cell division occurs after each DNA replication.

Following one round of DNA replication, meiosis involves two divisions known as meiosis I and II. Chromosomes divide during meiosis and mitosis, respectively. As the chromosomes of daughter cells, the two sister chromatids travel to opposing poles as the centromere divides during mitosis.

During meiosis I, one chromosome from each homologous pair moves to the opposite pole and the centromeres do not split.

The number of chromosomes is thus cut in half. Meiosis II, which takes place in both of the daughter cells formed after meiosis I, involves centromere splitting similar to mitosis; as a result, the number of chromosomes is the same as it was at the beginning of meiosis II, i.e., half of the original parent cell.

Option (c) is Correct. Both cytoplasmic with secreted proteins are always synthesized on free type of ribosomes.

Protein synthesis in eukaryotic cells is generally recognized to be compartmentalized; soluble proteins are produced on free ribosomes, whilst secretory and membrane proteins are produced on ribosomes that are associated to the endoplasmic reticulum (ER). Generally speaking, "free" polyribosomes create intracellular proteins like hemoglobin in red blood cells or contractile proteins in muscle cells.

The secreted protein first enters the endoplasmic reticulum, where it is subsequently produced by the ribosome. A more mature protein may result from the initial folding, assembly, and addition of certain sugar groups that take place in the endoplasmic reticulum lumen. The cytosol is where the majority of free ribosomal proteins are produced. Bound ribosomes produce proteins that are either used by the endomembrane system.

To use RFLP analysis to detect a single nucleotide polymorphism

(i.e., an SNP), the SNP must be present within the restriction enzyme recognition sequence.

To use RFLP analysis to detect a single nucleotide polymorphism (i.e., an SNP), the SNP must occur within a restriction enzyme recognition sequence.

When a single nucleotide in the genome is changed, SNPs, which are changes in the DNA sequence, take place. An alteration must be present in at least 1% of the population to be regarded as an SNP. One of the earliest methods for examining population genetic diversity was the restriction fragment length polymorphism (RFLP), which relies on restriction enzymes that snip DNA at particular locations. The sequences generated by these cuts are subsequently examined.

They are important because they are used to identify variations in a population's DNA and research genetic variation. RFLP will fail if SNP does not occur within restriction enzyme recognition.

The two main kinds of membrane transport proteins are carrier proteins and channel proteins.

There are typically two types of transport carried out by transport proteins: "facilitated diffusion," in which a substance is simply allowed to diffuse down its concentration gradient, and "active transport," in which a cell uses energy to move a substance in the opposite direction of its concentration gradient.

The specific solute to be transported is bound by carrier proteins (also known as carriers, permeases, or transporters), which then go through a series of conformational changes to move the bound solute across the membrane. Facilitated diffusion is the method by which these molecules travel across the membrane with the aid of specific transport proteins.
