- What is the role of DNA ligase in the elongation of the lagging strand during DNA replication?A: It catalyzes the lengthening of telomeres.B: It joins Okazaki fragments together.C: It unwinds the parental double helix.D: It synthesizes RNA nucleotides to make a primer.
- Dry matter is made up of organic matter and what else?
- Another word for genetic info is?
- prostaglandin will be produced and will travel to the corpus lute, where it will cause regression. The CL creates progesterone, which maintains pregnancy, so without it the embryo will be passed out of the tract as the cycle starts over.
- ____________ functions to promote bone maturation.
- ________________ regulates balance of osteoblast/osteoclast activity. ____________________ is the natural end of the menstrual cycle in females (average age is 50 in US). Post menopausal females don't release oocytes and no longer produce ____________. After menopause, estradiol levels decrease in females, increasing risk of _______________________.
- __________ acts as a brake on cartilage proliferation. It slows cartilage proliferation by increasing cell cycle inhibitors, decreasing the pool of _____________ chondrocytes. When it's overactive in achondroplasia it's exacerbated and leads to premature loss of resting chondrocyte population.
- Thyroid hormones (T3 and T4) function to _______________ bone maturation.
- _________________ is a congenital hypothyroidism that causes stunted growth with short adult stature, delayed bone maturation, delayed sexual maturity, and impaired intellectual functioning (distinctive gait). It is due to decreases of ____________ ______________ in ____________. Commonly due to __________ deficiency in mother, which are used to metabolize thyroid hormones. World Health Organization (WHO) puts 2 billion from 130 countries at risk of iodine deficiency.

- I. Diffuse --> chorionic villi spread evenly across placenta (mares, sows)II. Discoid --> chorionic villi located in two disc shaped ends of the placenta (primates, rodents)III. Zonary --> chorionic villi located in a band in the middle of the placenta (dogs, cats)IV. Cotyledonary --> chorionic villi located within cotyledons of ruminants; spread all over in discs on placenta
