Where does dna synthesis happen in eukaryotic cells

Biology
1 answer:
svetlana [45]4 years ago
6 0
In eukaryotic cells, the DNA synthesis happens in the nucleus of the cells. As to the location of the DNA, they are usually found in the nucleus of the cells. The synthesis of the DNA in the nucleus of the cells usually happens during mitosis and meiosis. Upon which that the cells begin to divide and multiply in number, DNA synthesis happens in their respective nucleus of the cells. While there are some DNA synthesis of cells that do not happen in the nucleus of the cells, for eukaryotic cells, they usually happen in the nucleus of the cells.

Destruction of the majority of the adrenal cortex would most likely result in decreased levels of ___________ and glucocorticoid
Alexus [3.1K]

Answer:

Destruction of the majority of the adrenal cortex would most likely result in decreased levels of mineralocorticoids, sex corticoids and glucocorticoids.

Explanation:

Adrenal glands are conical pyramid shaped glands. A pair of glands present above each kidney. It has an outer adrenal cortex region and inner adrenal medulla. Cortex and medulla secrete different hormones and are also regulated in different ways.

Adrenal cortex has three layers:

a. Outer zona glomerulosa: secretes mineralocorticoids like aldosterone - regulates the metabolism of sodium and potassium.

b. Middle zona fasciculata: secretes glucocorticoids like cortisol - regulates the metabolism of carbohydrates, fats and proteins.

c. Inner zona reticularis: secretes sex corticoids like Androstenedione -  stimulates the development of external sexual characteristics in males.

In a condition called Addison's disease, major part of the adrenal cortex is destroyed which results in deficiency of both mineralocorticoids and glucocorticoids. Symptoms include bronze like pigmentation of skin, low BP, low plasma levels of Na+, high plasma levels of K+, nausea, vomiting and diarrhoea.

4.4-1 Anaerobic Respiration
Vesna [10]

For lactic acid fermentation, the correct options are:

  • pyruvate
  • hydrogen
  • NADH
  • lactic acid
  • Lactic acid
  • pyruvate
  • mitochondria

For ethanol fermentation, the correct options are:

  • pyruvate
  • CO₂
  • acetyl CoA
  • acetyl CoA
  • acetaldehyde
  • Acetaldehyde
  • hydrogen
  • NADH
  • ethanol

<h3>What is a anaerobic respiration?</h3>

Anaerobic respiration is respiration which occurs in the absence of oxygen.

Oxygen is used as an electron acceptor during respiration. However, when oxygen is absent or insufficient, other molecules are used as electron acceptors in order to produce energy.

Anaerobic respiration in large organisms may result in the formation of lactate known as lactic acid fermentation.

In lactic acid fermentation, after glycolysis, the two pyruvate molecules receive hydrogen atoms from NADH creating lactic acid. Lactic acid can be converted back into pyruvate in the liver. The pyruvate can then enter into the mitochondria and cellular respiration, can proceed.

On the other hand, anaerobic respiration in microorganisms produce ethanol and is known as ethanol fermentation.

After glycolysis, the two pyruvate molecules lose a CO₂ atom, creating acetyl CoA. The acetyl CoA atom combines with hydrogen to form acetaldehyde. Acetaldehyde receives a hydrogen atom from NADH, resulting in the production of ethanol.

In conclusion, anaerobic respiration can occur either as a lactate fermentation or ethanol fermentation.

How do the products of meiosis compare to the original cell?
Gnesinka [82]

Answer:

Meiosis is the type of cell division in which a parent cell divides into four daughter cells. Meiosis generally occurs in the gamete or sex cells. The haploid cells are produced by the meiosis.

The original cell is diploid that contains the chromosome number (2X). The original is divided into the four daughter cell. The daughter cells produced by the meiosis contains the half chromosome number as compared with original cell (X). The crossing over occurs in meiosis and the daughter cells are quite different from the original cells.
