A single gene disorder is one that's known to be caused by a single gene. Multiple gene disorders, however, can be caused by multiple gene combinations and other factors. Dominant genes are always expressed in the offspring, while recessive genes are only expressed if the offspring recieves the recessive gene from both parents. Sex-linked genetic disorders occur most often in men, and are caused by a single-gene disorder gene being on the X chromosome but not the Y, so that the offspring needs only one recessive gene to have the trait/disorder.
Does this help? Any more questions?
The answer is; RNA is synthesized
Transcription is the first process of the central dogma where genes are turned into proteins. Transcription is mediated by RNA polymerase enzyme. The difference with DNA replication is that instead of the synthesized mRNA has Uracil in place of Thymine nucleotide. The RNA is also composed of ribose sugars instead of deoxyribose sugars.
Answer:
A callus is a hardening of skin, keratin is the protein which is abundant in callus. Skin is a protective layer against a external environment. Outer layer of skin consist of keratin which is also found in hair. Callus is the accumulation of dead cells result due to friction and pressure exerts on the part in which they are present. The keratin component (keratinocytes) remains undifferentiated in these dead cells which causes hardening in callus.
