At what stage of meiosis recombinant DNA is made?
At the stage of Pachytene of meiosis 1 recombinant DNA is made....
A synaptonemal complex disappears during?
After the pachytene stage, or in the end of it.
What stage is it when all the cells show crossover chromosomes?
The stage when all the cells show crossover chromosomes is the pachytene stage of meiosis. During this stage, homologous chromosomes pair up and exchange genetic material through a process called recombination or crossing over, which results in the formation of new combinations of genetic information.
How is prophase1 different in meiosis than in mitosis?
on prophase of mitosis the cylindrical shaped structure(centrioles) starts to move going to the both opposites sides as they move the fiber make-up structure starts to form(spindle). The spindles is the one who controls the movement of the choromosomes while it is in the process. note the chromosomes starts to become shorten ad thick that's why they r very easy to see. in prophase I of meiosis the choromoses condense and are seen to have splitinto two chromatids. One of its important features of the phrophase I of meiosis the paternal and maternal chromosomes come together in homologous pairs., well that's my answer i know its ryt... hope that i have helped you. -joan- The answer by joan simply states the processes that occur individually by mitosis and meiosis. The question is to discuss the 'Difference' instead of state the events that occur. In my understanding, prophase 1 of meiosis consists of 5 different stages - Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis. Now the question is which of these 5 stages differ from prophase of mitosis. I found that stages Leptotene (condensation of DNA) and Diakinesis (nuclear envelop fragments) are similar to that in prophase of mitosis. Thus, the difference has to lie in stages Zygotene (formation of bivalents and synaptonemal complex), Pachytene (crossing over at sites called chiasma) and Diplotene (separation of synaptonemal complex). Do improve on my answer. glenn
What are the five phases of meiosis 1?
Meiosis.....................produces gametes or sexual cells, which contain half the chromosomesbecause the sexual union of male and female will contribute the otherhalf.
Where crossing over is observed?
pachytene
At what stage of meiosis recombinant DNA is made?
At the stage of Pachytene of meiosis 1 recombinant DNA is made....
When does crossing over occur for oogenesis?
prophase I, exactly in pachytene the synaptonemal complex is formed between the thickened chromosomes and recombination or crossing over occurs.
A synaptonemal complex disappears during?
After the pachytene stage, or in the end of it.
What is the longest phase of meiosis?
The longest phase in meiosis is Meiosis 1.
What phase of meiosis does crossing occur?
prophase 1.
During what event of meiosis will chiasmata be observed?
during the pachytene stage of prophase-1 of meiosis -1 of meiosis ,the X shaped structure chiasmata is observed
What does the term crossing over mean in context of nuclear division?
Crossing over between pairs of homologous chromosomes to form chiasmata is known as pachytene. It occurs during prophase I in meiosis.?æ
What is genetic combination?
in meiosis, prophase 1( the longest stage ) there is a particular stage called PACHYTENE where there is crossing of the chromatids ( the arms of the chromosome) belonging to one paternal and one maternal. there is subsequent breakage and rejoining of the chromatids which results in variation called as genetic recombination.
What stage is it when all the cells show crossover chromosomes?
The stage when all the cells show crossover chromosomes is the pachytene stage of meiosis. During this stage, homologous chromosomes pair up and exchange genetic material through a process called recombination or crossing over, which results in the formation of new combinations of genetic information.
What are some nine letter words with 2nd letter A and 5th letter Y and 6th letter T and 8th letter N?
According to SOWPODS (the combination of Scrabble dictionaries used around the world) there are 1 words with the pattern -A--YT-N-. That is, nine letter words with 2nd letter A and 5th letter Y and 6th letter T and 8th letter N. In alphabetical order, they are: pachytene
Why is it necessary that DNA is packaged into chromosomes?
If DNA remained in a thread-like state it would be very difficult to effectively separate all the individual strands during any type of cell division. Discrete chromosomes created during the pachytene phase are much easier to separate cleanly.
