Where does a virus multiply?

1 answer:

3 0

virus can only multiply in the host cell ! without host cell , virus is likely to be dead !

so virus divides into host cells by using the host enzymes and DNA !

for more info, comment !

Give the nucleotide positions of all single-nucleotide polymorphisms (SNPs; nucleotide positions where individuals vary in a sin

krek1111 [17]

Answer:

1st has A and G whereas 2nd has C and T.

Explanation:

There are three common haplotypes present in the population. The first single nucleotide polymorphism has A and G alleles while on the other hand, the second single nucleotide polymorphism has C and T alleles. The four possible combinations of haplotypes for the above two single nucleotide polymorphisms are AC, AT, GC, and GT.

Which of the following is a step that occurs within an inflammatory response?

natka813 [3]

Inflammatory response can be defined is a reaction of the body to injury or destruction of tissues. This reaction serves to dilute, destroy or simply wall off the agent causing the injury and is localized around the area of injury.Inflammatory response takes place in the following steps:1. Tissue damage caused by injury or bacterial infection is detected.2. Vasodilators and chemotactic factors such as histamine are released.3. As a result, there is increased capillary permeability and blood flow to the area.4. There is migration of phagocytes to the site of infection.5. Phagocytes and specific serum proteins attack and destroy bacteria.<span>6. Inflammation dies down once intruder has been destroyed.</span>

Which of the following statements correctly describes any chemical reaction that has reached equilibrium?

Vesnalui [34]

Answer:

Option (d).

Explanation:

Equilibrium may be defined as the state of the equality on both the sides of the reaction. Different types of equilibrium are physical equilibrium, chemical equilibrium and dynamic equilibrium.

Chemical equilibrium may be defined as the equilibrium in which the reactants and products concentration remains constant with time. The rate of the backward reaction is equal to the rate of forward reaction.

Thus, the correct answer is option (d).

A segment of a DNA molecule has the base sequence ATGAAC. Write a shorthand structure for this segment and for its complementary

Zanzabum

Answer: See attached picture.

Explanation:

DNA or deoxyribonucleic acid is the name for the molecule that contains the genetic information in all living things. This molecule consists of two strands that wind around each other to form a double helix structure.

The basic unit of nucleic acids are called nucleotides, which are organic molecules formed by the covalent bonding of a nucleoside (a pentose which is a type of sugar and a nitrogenous base) and a phosphate group. So each nucleotide is made up of a pentose sugar called deoxyribose, a nitrogenous base which can be adenine (A), thymine (T), cytosine (C) or guanine (G) and a phosphate group.

<u>What distinguishes one polynucleotide from another is the nitrogenous base</u>, and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information, following the following criterion of complementarity: A-T and G-C. So the sequence of these bases along the chain is what encodes the instructions for forming proteins and RNA molecules. In living organisms, DNA occurs as a double strand of nucleotides, in which the two strands are linked together by connections called hydrogen bridges.

The chemical convention of naming the carbon atoms in the pentose nucleotide pentose numerically confers the names 5' end and 3' end ("five prime end" and "three prime end" respectively). The 5'-end designates the end of a DNA strand that coincides with the phosphate group of the fifth carbon of the respective terminal deoxyribose. A phosphate group attached to the 5'-end allows the ligation of two nucleotides; for example, the covalent bonding of the 5'-phosphate group to the 3'-hydroxyl group of another nucleotide, to form a phosphodiester bond.
