Answer:
The correct answer should be the second option, that is, Onion root tip cells do not undergo anaphase 1.
Anaphase I is a part of meiosis which occurs only in cells involved in reproduction. For example, gametes.
Onion root tip cells undergo mitosis.
The chromosome can be observed using compound microscope.
Thus, all other options are incorrect except second option.
Answer:
During sexual reproduction, two sex cells fuse to create a fertilized cell with a complete set of chromosomes. ... Result is 2 identical cells with 46 chromosomes.
Hope this helps:)
Answer:
U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U
Explanation:
The mRNA (messenger RNA) is produced via the process of TRANSCRIPTION, which is the first stage of gene expression in living cells. The mRNA sequence formed is further read in the ribosomes in a group of three nucleotides called CODONS. This reading is done by another type of RNA called transfer RNA (tRNA).
The tRNA uses a set of three nucleotide bases that are complementary to that of the mRNA codons called ANTICODON. The anticodons are complementary to the mRNA codon i.e. A on the mRNA sequence will be read and recognized by U on the tRNA anticodon.
Hence, given the mRNA sequence: A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A, the tRNA anticodons that will read this sequence will be: U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U
A simple light microscope should be enough. you can adjust it to a higher magnification. electronic microscope the magnification might be too high for this, but sure it can do the work too, especially when you're looking for a more detailed information
Type II restriction enzymes, such as Ecor I, that make staggered cuts within its recognition sequence, are considered more effective in biotechnology because they result in cohesive or sticky ends.
<h3>What is Ecor I and why are sticky ends important?</h3>
Ecor I is a kind of restriction enzyme which is obtained from Escherichia coli. The palindromic sequence recognized by this enzyme is 5' - GAATTC - 3'. It makes the following cuts between G and A on both the strands of the DNA to form sticky ends:
5' - G↓AATTC - 3'
3' - CTTAA↑G - 5'
Sticky ends are a fragment of DNA which is produced through a staggered cut, by the use of restriction enzyme. In this the terminal portion stretches with unpaired nucleotides. These kind of ends are easy to ligate when rDNA needs to be formed.
