Answer:
The repeating subunits of DNA are ribonucleotides whereas in RNA they are deoxyribonucleotides.
Explanation:
Ribonucleotides are repeating subunit of RNA while the deoxy-ribonucleotides are repeating subunits of DNA. That why RNA full form represent the ribonucleic acid and DNA represent deoxyribonucleic acid.
Actually the word "deoxy" means one oxygen is removed or less in DNA. The DNA lacks the one oxygen atom of hydroxyl group at carbon number two of ribose sugar. While RNA have the hydroxyl group at carbon number two of hydrogen atom.
The removal of one hydrogen atom in DNA make it more stable than RNA because DNA is made specifically to store genetic information and needed to be strong. The oxygen atom in RNA makes it vulnerable for attack by other biological molecules.
Answer:
The correct option is D. The nerve and red blood cells will turn on and off different portions of their DNA, using different genes to make different proteins.
Explanation:
A zygote is totipotent which means it has the ability to differentiate into any cell type found in the body along with the placental cells.
The nerve and red blood cells are specialized cells and they cannot differentiate into any other cell type.
All cells in the body are formed from the zygote. All the cells in the body have the same chromosomes and the same genes. However, these cells become specialized because certain part of the DNA is activated in one type of cell which helps it perform its function. Different genes are activated in different specialized cells which are able to transcribe and translate.
C. The product of mass and velocity of an object
I need a pic of the question plz
It is very difficult to conduct research on the shark's role in the ecosystem so scientists aren't sure what would happen if sharks became extinct. ... If the whale shark becomes extinct, there might be an increase in plankton. However, plankton are also eaten by several species of whale. I THINK THTAS THE BRAINLISET
