Elenna [48]

Answer:

True

Explanation:

Gel electrophoresis is a technique that is commonly used in the laboratory to separate charged molecules, like DNA, according to their size. The results of restriction digestion can be observed using this process. Restriction Digestion involves the process of cutting DNA molecules into smaller fragments using special enzymes called Restriction Endonucleases. And this way any inhibition of the restriction enzymes which prevents digestion can be observed and controlled.

Llamas have sexual reproduction. Some types of llamas have 74 chromosomes. That is how many chromosomes are in their somatic (bo
Sholpan [36]

Answer: 37 chromosomes.

Explanation: As is typical of mammals, llamas are diploid organisms, meaning that the number of chromosomes in each of their somatic cells is exactly twice of that found in the gametes (the so-called haploid number, referred to as "n"). If a particular species has 74 chromosomes in its somatic cells, we should expect to find 74/2=37 chromosomes in each gamete.
