Discuss and elaborate thoroughly the statement “oocyte activation involves inactivation” using specific molecular
evidence.
Step by step
Solved in 2 steps
- Using specific molecular evidence, elaborate on the remark "oocyte activation entails inactivation."With regard to primordial germ cells induction, explain how mammals are different from other organisms like worms, fruit flies, frogs and fish.Based on the results of 2D TLC separation, kindly compare the lipoidal components of egg yolk based on the distance traveled (first and second development) and then indicate the visualizing reagents where that spot/ analyte will give a positive result
- Explain the molecular mechanism of maternal effect.Explain the chromosomal and genetic control of sex determination in mammals. Clearly establish the difference between the primary and the secondary phases.why is it relevant to know the prevalence of premature rupture of membranes in adolescent pregnancy vs adult pregnancy?
- State how the distribution of nanos protein changes after fertilization.Discuss the concepts of: "MORPHOGENESIS" Also, cite examples to illustrate these concepts.Discuss and compare the source (mechanism) and types of increased mutations in older mother oocytes versus older father sperm (ch 4 and ch 7.) (Diagrams may be helpful if needed to convey your thoughts
- Carefully distinguish between the terms differentiation and determination. Which phenomenon occurs initially during development?explain briefly What is the rationale behind the cleavage stages undergone by the early embryo?Gametogenesis in mammals is a complex process. When comparing spermatogenesis and oogenesis, indicated whether the follow statements are true or false. After the S phase, both the spermatogonial stem cell and primary oocyte have the same number of double-copy chromosomes. #analyze Question 1 options: True False Both the first polar body and the second polar body have the same number of chromosomes. #analyze Question 2 options: True False After the S phase, both the spermatogonial stem cell and primary oocyte have the same number of double-copy chromosomes. #analyze Question 3 options: True False Both the primary oocyte and the secondary spermatocyte have double-copy chromosomes. #analyze Question 4 options: True False
