The relative amounts of each nucleotide base are tabulated here for four different viruses. Which virus has a double stranded RN

Biology
1 answer:
tatiyna2 years ago
3 0

Answer:

1. I and IV

2. II and III

3. I and II

Explanation:

The complete question is

Virus T C U G A

I 0 12 9 12 9

II 23 16 0 16 23

III 34 42 0 18 39

IV 0 24 35 27 17

The relative amounts of each nucleotide base are tabulated here for four different viruses.

Which virus has a single stranded DNA genome, a single stranded RNA genome, and which has a double stranded RNA genome?

Solution

RNA has "U" instead of T in its nucleotide sequence. Hence, both I and IV are RNA

DNA has T instead of U and hence both II and III are DNA

Virus I and II are double stranded RNA because they both have equeal number of base pair group

A=T and C=G

Large blue whales that are up to 30 meters long live primarily on ________ that is/are only about 6 cm long.
zalisa [80]

Large blue whales that are up to 30 meters long live primarily on krill that is/are only about 6 cm long.

Blue whales belong to the class of mammals. They are the largest animals on the Earth. They live in marine habitat. They can be more than 100 feet long. The weight of a single whale can be equal to 30 elephants. And they can live for as long as 80-90 years.

Krill are small animals belonging to the class of crustaceans. They are present in oceans. Krill are actually zooplanktons. They are majorly the food of whales. Krill are filter-feeders.

I need help, I don't understand this, so please try to explain?
Vinvika [58]

Answer:

Yeah, so basically the image is showing restriction enzymes. The job of restriction enzymes is mainly involved in research when scientists use them for cloning human genes. But that's besides the point...

Main thing you have to understand is that restriction enzymes cut at very specific places along DNA sequences. If you look at the restriction enzyme Rsa 1, you can notice that it cuts only between a thymine nucleotide base and an adenine nucleotide base. Next, if ya look at Sty 1 (be careful b/c W can represent adenine or thymine), it cuts only between two directly adjacent cytosine nucleotide bases!

SO.... if we go to Rsa 1, we can find the answers by dividing up the sequences between the pattern we saw in the gray box. It only cuts between adenine and thymine bases. Based on that, we can find the number of fragments created, and the segment lengths (basically just like how many nucleotide bases are in each strand). Hope ya found this helpful!

Define a chromosome and give more details about it​
solmaris [256]
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.

If all green plants in the world were distroyed which atmospheric gas will increase
Mila [183]

 Trees are a crucial part of the<span> carbon cycle</span>, a global process in which carbon dioxide constantly circulates through the atmosphere into organism and back again. Carbon is the second most valuable element to life, you know, after water. Anyway, trees take carbon from the atmosphere through <span>photosynthesis </span>in order to make energy. This carbon is then either transferred into oxygen and released into the air by <span>respiration </span>or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles andpollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.
