This particular area of genetics can be quite complex. So basically in DNA their is adenine, cytosine, guanine, thymine. So, then there is another step to this: Adenine links with Thymine (A is to T), and Cytosine pairs up with Guanine (C is to G). This is known as base pairing. However, when translating DNA to RNA their is a catch, there is no thymine in RNA. Instead there is Uracil. SO in RNA it would be like so: A is to U and C is to G. So when transcribing DNA to mRNA it would be like this. I will give an example: DNA: TGA GTC AAT GGC. However with RNA it would be like this, using the same example I just showed you: ACU CAG UUA CCG. Do you see I it now? Basically when transcribing to RNA you use the opposite of all of the original copy except use Uracil instead of Thmine.
Mitosis begins with replicated chromosomes i think
the correct answer is daughter cell
chhromosome=densly packed dna with histones and traits of Ca++
Allele-genes from the same locus but different chromosomes
Spindle fibers=mircotubules generated by the centrosome that transport the chromosomes to the opposite pole of the cell during indirect divison
Conjugation and transformation are both kinds of horizontal gene transfer that allow a cell to receive and recombine external DNA. Conjugation involves physical contact between two bacteria using a pilus, through which a copy of plasmid DNA is transferred from the donor (F+) cell to the recipient (F-) cell. Transformation, on the other hand, is simple uptake of naked DNA into a recipient cell from the environment. The DNA usually comes from the leftovers of a dead cell.
This is because the continents were joined together in a large landmass called Pangea. The theory of continental drift supports the statement that fossils and rocks that were similar in composition(makeup) and age were found on other continents because the continents were once joined together called Pangea
