Future treatment for diseases, such as HIV, involves

a. the removal of receptor proteins from the cell membrane

b. blocking recognition proteins on the HIV virus

c. blocking receptor proteins in the cell membrane

d. adding recognition proteins to the cell membrane

dna damages cause changes in the structure of the genetic material and prevents the replication mechanism from functioning and performing properly. dna damage and mutation have different biological consequences. while most dna damages can undergo dna repair, such repair is not 100% efficient.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
