The disease caused by the bacterium Clostridium tetani is: MCQ with Answer and Explanation

Explanation:
The Law of Segregation (Mendel's First Law) states that an organism possesses two alleles for each trait, and these alleles separate (segregate) during the formation of gametes (meiosis). Each gamete receives only one allele. This explains why a recessive trait can disappear in the F1 generation but reappear in the F2 generation.

Explanation:
The Wobble hypothesis, proposed by Francis Crick, explains the degeneracy of the genetic code. It states that the base pairing rules (A-U, G-C) are strictly followed for the first two bases of the mRNA codon, but the third base of the codon (the 3' end) can form non-standard or 'wobble' base pairs with the first base of the tRNA anticodon (the 5' end). This allows a single tRNA molecule to recognize and bind to more than one synonymous codon.

Explanation:
The dermis, lying beneath the epidermis, is a connective tissue layer containing collagen and elastin fibers, blood vessels, nerve endings, sweat glands, hair follicles, and sebaceous glands. The epidermis is the outermost protective layer, the hypodermis is subcutaneous fat, and the stratum corneum is the outermost part of the epidermis.
