Which is true of DNA viruses?
Maksim231197 [3]

Answer:

They use host cell machinery to produce new copies of their genome.

Explanation:

DNA viruses, which are similar to cells, directly employ cellular machinery to perform their process of replication, transcription of their genes, and DNA repair, that is, they use a host cell to make new copies of their genome. Because of this, some viruses have a large genome, such as herpesviruses, which make their own genes and become somewhat more independent of cell metabolism.  DNA molecules are found in two forms: linear and circular. Viruses of the polyomaviridae family have small genomes and circular DNA, while herpesviruses have linear dsDNA genomes. Viruses that have single strand genomes do not allow DNA repair.

DNA wrapped around histone proteins forms a material called ____ which condenses tightly to form _____ that can be seen with a l
makkiz [27]

Answer:

The correct answer will be-

1. Nucleosomes

2. Chromatin

3. Sister chroamtid

4. Centromere

Explanation:

The DNA is a very long molecule which if has to be passed on to the daughter cell as it is will cause problems. So, to reduce problems a cell form tightly packed structure of DNA so that they can be passed easily to the daughter cell.

The packaging of DNA begins with the wrapping of the DNA around histone proteins which forms the 11 nm basic structural units called nucleosomes. The nucleosomes start condensing each other and form 30 nm structure chromatin fibres.

The chromatin fibres undergo replication during S phase which produces an exact copy of the chromatin called sister chromatids bound to each other at a central point called centromere which helps the separation of the chromatids during M phase.

In liver cells, the inner mitochondrial membranes are about five times the area of the outer mitochondrial membranes. What purpo
m_a_m_a [10]

Answer:

Option (C).

Explanation:

Oxidative phosphorylation may be defined as the process of the production of ATP molecule by the use of enzyme and transfer of electrons from one complex to the other complex.

The liver cells has five times large surface area of inner mitochondrial membrane than the outer membrane. This increases the surface area of the inner mitochondrial membrane that increase the rate of the oxidative phosphorylation. The complexes of the electron transport chain is located in the inner mitochondrial membrane.

Thus, the correct answer is option (C).
