Haploid and diploid chromosomes are two types of chromosomes present in cells. Then, both have differences with regard to the number of chromosomes. Of course, the number of chromosomes in the cell content.
Chromosomes are double helix structures, which then accommodate the DNA and proteins present in the cell. In other words, chromosomes are strands of DNA chains containing the genes in living organisms. Then as a container for DNA and cell protein.
Furthermore, it will help in packing DNA. There is a long homologous chromosome with a centromere position and the staining pattern is the same as the gene in the appropriate location characteristics.

Both viral vectors and bacterial plasmids can be used to transfer genes into an organism. An invitro fertilisation could maybe be helpful, but not with engineered genes, but existing genes.
A) viral vectors is the best answer is viruses can be used to infect plants and change their DNA- bacteria aren't as good, as they can mostly be used to modify other bacteria only
Velocity is in relation to direction it is the speed plus direction it's going, and speed is distance over time
it should be the second one
Explanation: your right it is bacteria , could i pls get a brainlesttttt
It plays an important role in the menstrual cycle.
