Answer:
The population is decrasing
Explanation:
As we can see from the chart, the diversity of animals in Africa are being affected year after year. In 10 year gap 53,000 lions, 42,500 cheetahs and 12,500 zebras are dead and this is a dangerous sign.
So both the rabbits are Bb which means there will be a chart which comes out with one BB, Two Bb and one bb, For the rabbit to become brown fur it would need to get bb from theirs parents reproducing, if it's Bb they will just carry the trait recessive trait again and if it's BB they won't be carrying the trait
Ans: Option (B) Mitosis
DNA replication occurs just before the process of cell division, which is also called mitosis.
Mitosis is when the cell is being divided into two, and this is when DNA starts to replicate and it produces more and more cells and the process continues. In other words, mitosis<span> is a part of the cell cycle when replicated chromosomes are separated into two new nuclei. Before that process(mitosis), DNA replication occurs. Hence the correct option is (B) Mitosis.</span>
Answer:
The fragment and plasmid are both cut with the same restriction enzyme.
Explanation:
To insert a piece of DNA in a bacterial plasmid, we need to cut both plasmid and DNA insert from same regions. This is typically done by restriction enzymes or restriction endonuclease. This cutting will open the plasmid (which is circular initially) and produce <u>sticky ends.</u> Here, DNA insert can attach because of similar sequence (see attached figure). In the final step, DNA ligase will glue it in the plasmid and it will become its part. This technique has been extensively used as a DNA recombinant technology. A better representation can be seen in the attached figure where both DNA sequence of interest and plasmid are cut with the same restriction enzyme (shown as scissors) and then ligated with DNA ligase.
