i honestly dont k now and i wish you good luck
<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>
Be more specific with what you need help with please
Answer:
75%
Explanation:
This question involves a single gene coding for the ability to taste the chemical PTC. The allele coding for the ability to taste (T) is dominant over the allele coding for the inability to taste (t). This means that an heterozygous individual will have the ability to taste PTC.
According to this question, if two heterozygous tasters (Tt) cross to have a large family i.e. Tt × Tt, the following gametes will be produced by each parent;
Tt = T and t
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
TT, Tt, Tt - Tasters (3/4 or 75%)
tt - Non-taster (1/4 or 25%)
Note that based on the question asked, there is a 75% probability that their first child will be a taster because there is equal segregation of alleles into gametes.
Answer:
A. binomial system
B. According to taxon
Explanation:
A. The binomial system of nomenclature brings order to a chaotic world of common names. No two kinds of animals have the same binomial name, and every animal has only one correct name, as required by the International Code of Zoological Nomenclature, thereby avoiding the confusion that common names cause.
B. Any grouping of animals that shares a particular set of characteristics forms an assemblage called a taxon. For example, a housefly (<u>Musca</u> <u>domestica</u>), although obviously unique, shares certain characteristics with other flies (the most important of these being a single pair of wings). Based on these similarities, all true flies form a logical, more inclusive taxon. Further, all true flies share certain characteristics with bees, butter-flies, and beetles. Thus, these animals form an even more inclusive taxon. They are all insects.
