Answer:
3' - CCGTAATGTGATCCGGA - 5'
Explanation:
In DNA, the leading strand builds from a 5' to 3' direction and the lagging strand (complementary strand) must build from a 3' to 5' direction.
The base-pairing rules for DNA are:
- adenine always pairs to thymine (A to T) (T to A)
- guanine always pairs to cytosine (G to C) (C to G)
Ans.
Human reproduction involves release of sperm (male gamete) and egg (female gamete) and their fusion to form zygote that develops into embryo. In females, an egg is released each month as a part of a monthly cylce, called menstrual cycle. The release of egg is termed as ovulation, in which tiny eggs are send into the fallopian tubes for fertilization.
Hence, the correct answer is 'a). an adult female usually releases an egg from an ovary each month.'
Wernicke-korsakoff syndrome is associated with the decreased absorption and utilization of thiamin. The correct answer is c. thiamin..
The neurological condition Wernicke-Korsakoff syndrome is brought on by a lack of vitamin B1 (thiamin). There is no distinction between Korsakoff syndrome and Wernicke encephalopathy. The disease process is the same but at various stages. Both result from brain damage brought on by a deficiency in vitamin B1.
A prevalent deficiency in vitamin B1 is found in patients with alcohol use disorders. Additionally, it frequently affects persons whose bodies do not adequately absorb meals (malabsorption). This can occasionally happen after bariatric surgery or in conjunction with a chronic condition.
Following the disappearance of Wernicke encephalopathy symptoms, Korsakoff syndrome frequently appears. The thalamus and hypothalamus, two lower regions of the brain, are damaged as a result of Wernicke encephalopathy. Memory-related brain regions suffer permanent harm in people with Korsakoff syndrome.
