Because the RNA molecules that are in most organisms can’t replicate themselves. Further, the RNA molecule that is in most organisms can’t transcribe its information on the DNA.
The DNA molecule readily replicates itself under the right conditions. The reason that DNA molecules replicate themselves much easier than RNA molecules is because DNA has a double helix structure.
The double helix can unzip down the middle, creating two molecules with complementary information.The RNA is generally a single string of base pairs. RNA isn’t double anything. So an RNA molecule usually can’t divide into two molecules with complementary informaiton.
That being said:
RNA molecules in some virus species can replicate itself. This RNA can transcribe information onto the DNA of the host organism.
RNA molecules with a certain structure under the right conditions can replicate themselves. However, replication in RNA is not as reliable as replication of DNA. That is one reason that RNA viruses mutate at a much faster rate than most DNA viruses.
Answer:
A
Explanation:
1 half-life = .4 kg = 15 years
2 half-life = .2 kg = 30 years
3 half-life = .1 kg = 45 years
4 half-life = .05 kg = 60 years
They have uncoiled to form long, thin strands.
Interphase is made up of G1, S, and G2 phases where S is the synthesis phase and G2 prepares the cell for mitosis/meiosis.
Answer:
Genes are made up of DNA.. DNA is the molecule that is the hereditary material in all living cells. The color of your hair,skin,eyes etc,, are all controlled in part by your genetic information

Answer:
12th May at 4.17 PM
Explanation:
This is because this is during the low tides and the low tide is at its lowest, at -0.7, m than any other date or time of the month. This means that most of the shoreline has receded deep into the ocean and exposed most of the continental shelf than any other time. This leaves rooms for more sea shells to be exposed and easily collected.
