Which of the following is a contrast in genetics organization between COVID19’s RNA & human DNA
a) RNA coils to form a helix bending along the nuclear envelope while DNA condenses to form chromatin
b) RNA stabilizes its structure using nucleoproteins while human DNA uses histones
c) RNA uses host cell replication machinery to proliferate while DNA does not
d) RNA is shorter since it codes for 5 genes instead of 20,000 genes like in DNA
e) RNA consists of ribonucleic acids whereas DNA consists of deoxyribose nucleic acids
Is the following statement true or false?Why? “The flow of genetic information in the cell is alwaysDNA -> RNA -> protein.”
Neema wants to determine whether or not the nucleus of a cell differs in the chemical compounds they contain or not from species to species. She is planning on working with the nucleus of a human and the nucleus of a mouse. She has removed all of the DNA from each nucleus, then has selected and isolated one DNA fragment from each species. What results can Neema expect if she takes the human DNA fragment and inserts it into the mouse nucleus and then inserts the mouse DNA fragment into the human nucleus? Use your knowledge of DNA replication to answer.
