Your sister who taking the genetics course, approaches you with a problem set to solve and seeks you help. She provides you with the following pedigree. Based on your expertise, which of the following patterns of inheritance listed below can and/or cannot be excluded? 00 Answer either “Can be excluded" or “Cannot be excluded". (a) Autosomal recessive: (b) Autosomal dominant: (c) X-linked recessive: (d) X-linked dominant: (e) Sex-influenced, dominant in females: (f) Sex-influenced, dominant in males: Based on your answers for c) and f), provide your reasoning for each mode of inheritance as to why you concluded that they can or cannot be excluded.
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
