What are two basic differences between DNA and RNA? RNA is usually single stranded, while DNA is usually double stranded. RNA co
ntains uracil, while DNA contains thymine. RNA is usually double stranded, while DNA is usually single stranded. RNA contains thymine, while DNA contains uracil. RNA doesn’t contain cytosine, while DNA doesn’t contain adenine.
<span> Both of them are nucleic acids. And that is about the only similarity they share. ;)
One of the major differences between the two is that DNA is double-stranded and RNA is single stranded. Also, DNA contains the nucleotide T whereas RNA contains U.
RNA copies the genetic information found within DNA and uses it to assemble protein, as well as ribosomes. Hence, RNA is a crucial part in protein synthesis, being directly involved in it, whereas DNA is indirectly involved in this process.
There are three types of RNA: mRNA (messenger RNA), rRNA (ribosomal RNA) and tRNA (transfer RNA). As far as DNA is concerned, there is only one type of DNA. ;) Another difference.
Also, in some viruses the RNA replaces the DNA but the DNA will never replace the RNA. Yet another difference. </span>
Metamorphic rocks are almost always harder than sedimentary rocks. They are generally as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded away.
Because their mineral grains grew together tightly during metamorphism, they're generally strong rocks.
As it is given in the question that both the plant belongs to same species and according to biological species concept, a species can be defined as the largest group of organisms in which any two two individuals of the opposite sex breed to produce a fertile offspring.
According to this the correct answer is D) They can produce offspring plants that also produce fertile seed.
