D. Tubulin. Cilia and flagella are motile structures found on the surface of cells. They are composed of microtubules made of tubulin protein and are anchored to the cell by basal bodies. Cilia are typically shorter and more numerous than flagella, which are longer and usually occur singly or in pairs.

The movement of cilia and flagella is facilitated by the interaction of the cytoskeleton with motor proteins, specifically dynein. Dynein is a type of ATPase enzyme that binds to microtubules and uses energy from ATP hydrolysis to slide the microtubules against each other, causing the cilia or flagella to bend. This bending motion propels the cell or moves fluid or particles along the cell surface.

A lab test called the fecal occult blood test (FOBT) is used to examine stool samples for undetectable blood (occult blood).

Though not all tumors or polyps bleed, occult blood in the stool may be an indication of colon cancer or polyps in the colon or rectum.

Typically, occult blood is passed in such minute volumes that a fecal occult blood test is the only way to detect it. A fecal occult blood test may reveal blood, in which case other tests may be required to identify the cause of the bleeding. The fecal occult blood test can only determine if blood is present or absent; it cannot identify probable bleeding causes.

Detect colon cancer. Your doctor could advise a fecal occult blood test once a year to check for colon cancer if you're 50 years of age or older and at average risk of developing the disease. However, you could also require further screening exams that provide the doctor a direct view of your colon.

Examine potential reasons for unexplained anemia. The inability of your healthy red blood cells to provide enough oxygen to your tissues is known as anemia. Fecal occult blood testing is sometimes done to identify whether internal bleeding, such as from a bleeding ulcer, is causing your anemia.

The structures that secrete hormones important in the maintenance of pregnancy are Corpus luteum, Placenta, and Trophoblast cells.

Corpus luteum is a temporary structure formed in the ovary after ovulation, and it secretes the hormone progesterone, which plays a crucial role in the maintenance of pregnancy. Progesterone prepares the uterus for implantation of the fertilized egg, maintains the uterine lining during pregnancy, and prevents the onset of labor until the end of pregnancy.

The placenta, which is formed from the outer layer of cells of the developing embryo, secretes a range of hormones, including estrogen, progesterone, and human chorionic gonadotropin (hCG). These hormones help to maintain the pregnancy by promoting growth of the uterus and preventing menstruation.

Trophoblast cells are the outer layer of cells that surround the developing embryo and form the placenta. They secrete hormones such as hCG, which helps to maintain the corpus luteum and continue the secretion of progesterone. Trophoblast cells also secrete other hormones such as human placental lactogen (hPL), which plays a role in regulating maternal metabolism during pregnancy.

The inner cell mass and myometrium do not secrete hormones important in the maintenance of pregnancy. The inner cell mass is the cluster of cells inside the blastocyst that will eventually develop into the embryo, while the myometrium is the muscular wall of the uterus that contracts during labor to help push the baby out.

During pregnancy, the production of hormones is essential to ensure proper fetal development and the maintenance of the pregnancy. The structures that secrete hormones important in the maintenance of pregnancy include the corpus luteum, placenta, and trophoblast cells.

The corpus luteum is a temporary gland that forms in the ovary after ovulation. It secretes progesterone, a hormone that helps thicken the uterine lining and maintain the pregnancy in its early stages. If fertilization occurs, the corpus luteum will continue to produce progesterone until the placenta takes over its function.

The placenta is the primary endocrine gland during pregnancy, and it secretes several hormones such as human chorionic gonadotropin (hCG), estrogen, and progesterone. hCG is the hormone detected in pregnancy tests, and it supports the corpus luteum's function, ensuring continued production of progesterone. Estrogen also plays a crucial role in pregnancy, supporting fetal growth and development.

Trophoblast cells are cells that surround the developing embryo and later become part of the placenta. They secrete hormones, including human placental lactogen (hPL), which helps regulate maternal metabolism and supports fetal growth.

The myometrium is the muscular layer of the uterus, and while it does not secrete hormones, it responds to hormonal signals during pregnancy, contracting to facilitate delivery. The inner cell mass, which becomes the embryo, does not secrete hormones either.

In summary, the corpus luteum, placenta, and trophoblast cells are the structures that secrete hormones important in the maintenance of pregnancy, playing a crucial role in fetal growth and development.

TRANSCRIPTION AND TRANSLATION

Genes provide information for building proteins. They don’t however directly create proteins. The production of proteins is completed through two processes: transcription and translation.

Transcription and translation take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA.

The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines.

DNA → RNA → Protein

DNA and RNA are similar molecules and are both built from smaller molecules called nucleotides. Proteins are made from a sequence of amino acids rather than nucleotides. Transcription and translation are the two processes that convert a sequence of nucleotides from DNA into a sequence of amino acids to build the desired protein.

These two processes are essential for life. They are found in all organisms – eukaryotic and prokaryotic. Converting genetic information into proteins has kept life in existence for billions of years.

DNA and RNA

RNA and DNA are very similar molecules. They are both nucleic acids (one of the four molecules of life), they are both built on a foundation of nucleotides and they both contain four nitrogenous bases that pair up.

A strand of DNA contains a chain of connecting nucleotides. Each nucleotide contains a sugar, and a nitrogenous base and a phosphate group. There is a total of four different nitrogenous bases in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C).

A strand of DNA is almost always found bonded to another strand of DNA in a double helix. Two strands of DNA are bonded together by their nitrogenous bases. The bases form what are called ‘base pairs’ where adenine and thymine bond together and guanine and cytosine bond together.

Adenine and thymine are complementary bases and do not bond with the guanine and cytosine. Guanine and cytosine only bond with each other and not adenine or thymine.

There are a couple of key differences between the structure of DNA and RNA molecules. They contain different sugars. DNA has a deoxyribose sugar while RNA has a ribose sugar.
