Which of the following cell undergoes first meiotic division during spermalogenesis? ASpermatogonium BPrimary spermatocyte CSecondary spermatocyte DSpermatidSubmit During the meiotic division the AHomologous chromosomes are separated BThe linkage is disturbed CThe homologous chromosomes do not segregate...
You observed an organism in which the zygote undergoes meiosis. What type of life cycle is present in this organism? On what day does the fertilized egg gets implanted in the uterus? What events take place between the exposure of the oocyte to spermatozoa and the formation of the ...
During a plant's life cycle, it undergoes alternation of generations whereby it has a multicellular diploid phase (called the sporophyte) and a multicellular haploid phase (called the gametophyte). The sporophyte undergoes mitosis to make more diploid cells, but...
8. An oocyte is a cell which undergoes meiosis to produce an ovum or egg. 9. A catalyst is a substance that can speed up the rate of a chemical reaction without changing its own structure. 10. A black hole is a celestial body which has approximately the same mass as the sun and a...
In the presence of high cellular sterol concentrations SCAP confines SREBP to the ER. With low cellular concentrations, SCAP escorts SREBP to activation in the Golgi. There, SREBP undergoes two proteolytic cleavage steps to release the mature, biologically active transcription factor, nuclear SREBP (...
Which of the following are characteristics of a sporophyte of Bryophytes ? I. Multicellular sporophyte. II. Completely or partially dependent on the gametophyte. III. Undergoes a reduction division to from spores. View Solution Select the be option with the correct sequence of events in the cycle...
What is the parent cell in meiosis? I. Alleles A, B, C, and D are linked on one chromosome, and alleles a, b, c, and d are linked on the homolog. During meiosis, a crossover event occurs between genes A and B. Which of ...
Which step in meiosis causes a change in the ploidy level (N versus 2N) of the cells that will become gametes?Overview of Meiosis:Meiosis is the type of cell division by which diploid germline cells give rise to haploid gametes. In total, meiosis ...
To determine in which of the following cases a zygote further develops to form a diploid structure, we need to understand the life cycles of different organisms, particularly focusing on the processes following zygote formation.1. Under
