Answer:
a) What evidence in the article supports the claim that this is a severe problem?
The structure that surround and protect the cell depends on the cell type: for plants cells it would be a cell wall whereas for an animal cell it would be the cell membrane :)
Answer: Option C
Explanation:
Protein building begins on the DNA strand. Usually, the DNA contains genetic information which flows from nucleic acids to proteins in a series of steps:
1) Replication: this is the first step. It involves the copying of parental DNA into daughter copies.
2) Transcription: this is the second step. Here, parts of the coded genetic message in DNA are copied precisely in the form of RNA - in the form of messenger RNA (mRNA).
3) Translation: this is the third step. Here, genetic message coded in mRNA is translated, on the ribosomes, into a protein with a specific sequence of amino acids.
Simply put, DNA makes RNA, and RNA makes protein.
Answer:
Lipids and proteins
Explanation:
It gets lipids from the membrane of the host cell it attaches to.
The proteins on the envelope are from the original virus itself.
