Answer: A gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. A chromosome is a long DNA molecule with part or all of the genetic material of an organism. A allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Explanation:
Answer:
Explanation:
It is given that
B is the dominant allele which represents the black color
and b is the recessive allele which represents the white fur.
B being dominant will result into black color fur for genotype "Bb"
Given -
Frequency of black fur allele (p) is
As per Hardy Weinberg's first law of equilibrium
Substituting the value of p in above equation, we get -
q represents the frequency for white fur allele
Frequency of white fur phenotype is
Frequency of homozygous black fur phenotype (BB) is
As per Hardy Weinberg's second law of equilibrium -
Combined frequency of homozygous and heterozygous black fur phenotype is
Answer: Option C.
GAL80 would be able to bind to GAL4, and transcription of the genes involved in galactose metabolism would be repressed.
Explanation:
Gal 3, Gal 80 and Gal 4 are form of proteins which participate in metabolism. They constitute a galactose-responsive switch for the GAL genes When galactose is absent, Gal 80 bind to Gal 4, masking the Gal4AD prevent gene transcription and prevents Gal4-mediated promoter activation
