In rabbits, the allele of the gene for short hair (S) is dominant over the allele for long hair (s) and the black hair (B) is dominant over brown hair (b). The hair color and hair length genes are on separate pairs of chromosomes. For a cross between a SsBb and a ssBb rabbit, what are the expected genotypes and phenotypes in the offspring?
Since the two strands of the DNA molecule are complementary, for any given gene:
A. The RNA polymerase can bind to either strand.
B. Only one strand actually carries the genetic code for a particular gene.
C. Each gene possesses an exact replica that can be used should a mutation occur.
D. A gene transcribed in the 5' to 3' direction on one strand can be transcribed in the 3' to 5' direction on the other strand.
During transcription of DNA to RNA:
A. the RNA polymerase moves along the DNA in the 5' to the 3' direction.
B. the 3' end of the RNA molecule is produced first.
C. an RNA polymerase must first bind to a promoter sequence.
D. transcription is always initiated at a "start codon"
During "RNA processing"
A. all of the exons are removed and discarded
B. the RNA molecule is made from a DNA template
C. introns are cut from the RNA and the exons are spliced together
D. the RNA molecule is translated into a protein molecule
Consider a population of 10,000 individuals with the following allele frequencies: A = 0.7, a =0.3. How many AA homozygotes do you expect to find based on the Hardy-Weinberg equation (p2 + 2pq + q2 = 1)
E. None of the answers listed above are correct
