The annealing between the primer and the. target gene is an equilibrium reaction, and the annealing reaction proceeds with a smaller Î´G (see lower right. Figure on the previous page). 2.3 GC content. Primers are designed so that their GC content is between about 40% to 65%. Primers with GC content between 50% and 60% tend to give relatively good primers. 2.4 Secondary structure. It is important, particularly for the Inner primer, that primers are designed so that they do not form secondary. structures.
Kids are dewormed the first time at one month of age at Onion Creek Ranch. Deworming kids at an earlier age won't hurt them, but it is a waste of time and money, because they don't begin to eat significant amounts of solid food until they are about three weeks old.
Deworming medications are available as tablets, capsules, granules, chewables, liquids, and topicals. Puppies and kittens are born with worms and should be dewormed early. Waiting until 6-8 weeks of age to worm puppies and kittens allows them to spread worm eggs that will contaminate the soil and re-infect them. Puppies: Deworm every 2 weeks from 2 weeks of age to 3 months, then deworm monthly until 6 months of age.
