PLEASE ANSWER THESE QUESTIONS

1.The annotated sequence of the HIV genome allows biologists to identify drugs that can interfere with the HIV cycle and prevent infection.  The annotated genome of HIV containing the open reading frame BLANK , which is a gene that encodes protein components of the capsid,BLANK , which encodes proteins needed for reverse transcription and incorporation into the host DNA, and BLANK, which encodes proteins that are embedded in the lipid envelope.

2.In bacteria, the supercoils of DNA form a structure with multiple loops called a BLANK . The supercoil loops are bound together by BLANK .

3.Viruses can bind to surface receptor molecules on cells of the host organism, enabling the viral genome to enter the cell, and will use the host cell's machinery to replicate, transcribe, and translate their genome in order to make more viruses.

True

False

4.Polyploidy is especially prominent in what group of organisms?

Bacteria and archaeons

Animals and Fungi

Plants

Protozoans

5.Which of the following have genomes that are information dense, meaning that most of the genome has a defined function? 90% or more of the genome consists of protein-encoding genes.

Bacteria

Archaeons

Viruses

Eukaryotes

6.The [BLANK] refers to all the genetic material of an organism that is transmitted from parents to their offspring.

Explanation / Answer

Ans. 1

gag gene encodes protein components of the capsid.

pol encodes proteins needed for reverse transcription and incorporation into the host DNA.

env encodes proteins that are embedded in the lipid envelope.

2-

In bacteria, the supercoils of DNA form a structure with multiple loops called a nucleoid . The supercoil loops are bound together by protein core .

3-

True

4- (C )Polyploidy is especially prominent in Plants.

5- (A) bacterial genomes are information dense as they have no introns and 90% or more of the genome consists of protein-encoding genes.

6-

The genome refers to all the genetic material of an organism that is transmitted from parents to their offspring.
