Explain how the VIH virus uses specific structures to enter the cell

Biology
1 answer:
Alona [7]2 years ago
4 0

Answer:

When HIV infects a cell, it first attaches to and fuses with the host cell. Then the virus uses the host cell's machinery to convert the viral RNA into DNA and replicate itself. The new copies of HIV then leave the host cell and move on to infect other cells.

How do cells at the completion of meiosis compare with cells that are in prophase of meiosis I? (A) The cells have half the numb
Sedbober [7]

Cells at the completion of meiosis compare with cells that are in prophase of meiosis I is (A) The cells have half the number of chromosomes and half the amount of DNA.  

The correct option is (A).

  • The cells produced at the end of meosis cell division have half the number of chromosomes (termed as Haploid), so they will have half the number of chromosomes but same DNA as that of the parent cell as DNA divides and makes a copy of the parent cell DNA.
  • Meiosis is a form of cell division of germ cells that creates gametes such as sperm or egg cells in sexually reproducing animals. It consists of two rounds of division that result in four cells with just one copy of each chromosome (haploid). Prior to division, genetic material from the paternal and maternal copies of each chromosome is crossed across, resulting in novel code combinations on each chromosome.
  • During fertilisation, the haploid cells generated by meiosis from a male and female will unite to form a zygote, a cell with two copies of each chromosome.
