If Polaris were to go supernova today, no one currently on Earth ever know it happened because it would take 434 light years to reach the Earth
Explanation:
The Polaris or the North Star that we can see at the North Pole of the Earth in the night historically dates back to 434 years in the past. If the Polaris becomes a supernova or if it dies now, it will take 434 years in the future from now to know about it.
This is simply because ‘one light year is the distance traveled by light in one year’. Hence currently, one cannot know about what happened to the Polaris supernova even if it happens now.
Answer:
In sexual reproduction, traits will be taken from both parents, so the child will be a mix of traits from the father and the mother
In asexual reproduction, there is only one parent, so the child will be a genetical replica of the parent
The complete question is:
a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have
A) T2 protein and T4 DNA
B) T2 protein and T2 DNA
C) a mixture of DNA and proteins of both phages.
D) T4 protein and T4 DNA
E) T4 protein and T2 DNA
A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.
A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.
- The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria.
- Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.
- As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.
In conclusion, The new phages produced would have D) T4 protein and T4 DNA.
