Deoxyribose sugar and phosphate group
Are nucleotides
Answer:
si, lo es porque mutaciones es lo que ayuda a los animales a cambiar en un certo punto de tempo (evolutivo).
Explanation:
Answer:
1. Cells are composed of chemicals and both the structure and function of cells are regulated by the basic principles of chemistry. true
2. Scientists have successfully sequenced the entire genome of humans but have not yet sequenced the entire genome of any other species. false
3. Living systems are the most complex chemical systems on earth. true
4. Living systems are governed by the same principles of chemistry and physics that govern non-living systems. true
5. Living organisms contain unique chemical elements which are not found in non-living systems. false
6. An input of energy is required to maintain the complexity of living systems. true
7. The energy conversions that take place in living systems are governed by the same laws of thermodynamics that govern non-living systems. true
Explanation:
Cells are the basic unit of life which differentiate a living thing from a non- living thing. Although a living system, is made of the same chemical elements from which a non-living t=might be made, yet they are different from the non-living things as living things carry out the seven basic principles of live.
All living things carry genetic material from which their genome is made. Scientists have currently been able to sequence the genome of humans as well as many other organisms.
The total magnification would be 600x as you would obtain the total magnification by multiplying the objective lens magnification and the eyepiece magnification together.
40 • 15 = 600.
The process of RNA editing is the alteration of the sequence of nucleotides in the RNA after it has been transcribed from DNA, but before it is translated into a protein. RNA editing occurs by two distinct mechanisms:<em><u /><u>Substitution</u> <u>editing </u></em>and <u><em>Insertion/</em></u><em></em><u><em>deletion</em></u><em> <u>editing</u></em>.
<u><em>Substitution editing</em></u> is the chemical alteration of individual nucleotides. These alterations are catalyzed by enzymes that recognize a specific target sequence of nucleotides:
*Cytidine Deaminases that convert a C in the RNA to uracil.
*<em />adenosine deaminases that convert an A to inosine,which the ribosome translates as a G.<span>Thus a CAG codon</span><span> (for Gln) can be converted to a CGG codon (for Arg).
<em><u>*Insertion/deletion editing</u></em><em><u /></em><u /> is the insertion or deletion of nucleotides in an RNA.
These alterations are mediated by guide RNA molecules that base-pair as best they can with the RNA to be edited and serve as a template for the addition( or removal) in the target.</span>
