At the end of prophase, the DNA has replicated itself by semi-conservative replication. So there're 92 DNA molecules at that time (46 * 2 = 92). However at telophase, the Cells have divided, each having 46 dna molecules.
Can you please post the complete question?
oh yeah sorry...just wait a sec
The first sterile hybrid is made by meiosis. So the no. of chromosomes in this hybrid will be 14. Due to mutation, this number gets doubled, so now the fertile hybrid 1 will have 28 chromosomes. Now when this fertile hybrid 1 is crossed with a another grass having the chromosome no. 14, the resulting offspring will have 21 chromosomes (7 from the grass, and 14 from the fertile hybrid one). Again, due to mutation this sterile hybird formed have its chromosome no. double, so the next fertile hybrid 2 will have 42 chromosomes (21 * 2 = 42)
Thank you!
See you're given the mRNA code and you need to get the tRNA code for each.
yes please solve...would be grateful
Okay.yes please solve...would be grateful
oh good!
Don't worry. This happens. You will improve with every paper. Just keep up the practice.
Good.
thank you!
You should continue.
Yes they do, sometimes. But even if they don't, the pattern on which they are asked remains the same. But you should be prepared for any new question which may come; you should treat every question as a new one. Just keep practicing, you'll get better by time. When I started doing them, I also used to get marks like 29, 32 etc. But now I have improved a lot, and now alhamdolillah most of the times i get 40/40.
