Amoxicillin is a broad-spectrum antibiotic widely used for certain
bacterial infections in the ear, nose, throat, genitourinary tract, skin, lower
respiratory tract, and its also used to treat gonnorhea. Amoxicillin is a
fairly strong drug, and it can elicit an allergy to patients even to those who
had used the drug before and did not experienced any untoward problems. If the patient
had symptoms such as difficulty in breathing, itching, and untoward swelling or
lump in the throat when receiving treatment with penicillins like amoxicillin,
sulbactam, ampicillin, methicillin, or penicillin G, the nurse should
discontinue giving amoxicillin and report to the doctor right away.
It’s not so much that the alleles separate but more so that only one of the parental alleles is passed on. Let’s look at a monohybrid trait to make this easier to comprehend, and let’s say the trait is eye color. One of the parents has blue eyes, a recessive eye color, meaning both of their alleles for that trait are recessive. However, the other parent has brown eyes, a dominant eye color, meaning this parent could either possess one dominant allele that hides the recessive blue (let’s just limit it to two colors to avoid confusion) or they could have two dominant alleles. When gametes are formed, they consist of a combo of alleles, one maternal and one paternal. Meaning, in the case of the heterozygous dominant parent (or the parent with one dominant and one recessive allele) they could either pass on their dominant allele, giving the child brown eyes, or their recessive allele, giving the child blue eyes because they can only ever inherit the recessive trait from the other parent. The law of segregation essentially says that a parent cannot clone itself and create a child in its exact image but rather that the child would inherit one trait from each parent. This is why the child has two alleles for the trait and the parents both have two alleles for this trait. Hope this helps (:
The genetic code is said to be redundant in that the same amino acid residue can be encoded by multiple, so-called synonymous, codons
Answer:
Muscles at the microscopic level are made of actin (thin filament) and myosin (thick filament) fibers in alternation and parallel to each other. During contraction, the fibres seem to slip against each other in opposite directions. Technically, the myosin head ‘walks’ on the actin – in an engage and release motion – with the help of ATP. Several actin and myosin fibers make up a myofibril. Each contractile unit in the myofibril is called a sarcomere – viewed as Z-discs at the microscopic level.
