Enzymes split the DNA molecule into two rails and then transport corrisponding nitrogen bases to each rail.
Answer and Explanation:
This happened because when the agar was desiccated, all the water was released, but the solutes used in the culture medium remained in the petri dish, that is, all the nutrients remained available to H. salinarium, which survived by consuming these nutrients. Although the growth of H. salinarium requires a higher level of NaCl than the level left in the petri dish, we can consider that some colonies of H. salinarium adapted to the low level of NaCl and managed to survive, passing this characteristic to new colonies.
Answer:
A karyotype test looks at the size, shape, and number of your chromosomes. Chromosomes are the parts of your cells that contain your genes. Genes are parts of DNA passed down from your mother and father. They carry information that determines your unique traits, such as height and eye color.
People normally have 46 chromosomes, divided into 23 pairs, in each cell. One of each pair of chromosomes comes from your mother, and the other pair comes from your father.
If you have more or fewer chromosomes than 46, or if there is anything unusual about the size or shape of your chromosomes, it can mean you have a genetic disease. A karyotype test is often used to help find genetic defects in a developing baby.
