Identify and describe one or two structural and functional differences between prokaryotic and eukaryotic cells that you believe contribute to the ability of eukaryotic cells to form the specialized
There is an international conference that has been called to promote research in biomimicry that will have applications in genetic engineering and in biotechnology.
If a rabbit breeder crossed a pure-bred white normal-coated male with a pure-bred black Havana female with satin coat and all the offspring were Havana black with normal coats.
The development of DNA and genetic analysis has opened up a whole new branch of biological investigation: molecular phylogeny.
If 9% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be more resistant to malaria because they are heterozygous (Ss) for the s
There are a 100 feral pigs on a island in which 75 individuals are solid black and 25 are black and white spotted, the recessive phenotype.
Biotechnology and genetic engineering is changing rapidly. Do you think this pace is safe? Why or why not? What are your thoughts on cloning, genetic screening and manipulation.
What is the sequence of events that takes place to go from gene to protein. I know there is a set of nucleic acids involved in this process. Identify these nucleic acids and explain their function i
Early in the last century, English physician Archibald Garrod noticed that about half the albinos he saw in the course of his practice were the children of first cousins who had married each other.
Kruppel and giant are 2 gap genes in drosophila for which the maternal effect gene bicoid serves as a transcriptional activator.
In a particular random mating population, the frequency of the O allele of the ABO blood group system is .6, the frequency of A is .3, and the frequency of B is .1.
The Planning ,Research and Development , Corp. is seeking grant money to continue their investigation on the relationship between DNA and heredity.
This is the way my textbook answered it "using the product rule(because the inheritance of each gene is independent), she can make 2x1x1x1= 2 different types of gametes. Please explain.
In humans, red-green color blindness is recessive and X-linked, while albinism is recessive and autosomal. What types of children can be produced as the result of marriages between two homozygous pa
Four Hfr stains of E. coli are known to transfer their genetic material during conjugation in different sequences.
Estrogen receptor (ER) is an important transcription factor, which is up-regulated in 70% of all breast cancers. Using the known ER motif to scan the genome yields many thousands matches.
A population of iguanas on the Galapagos Islands has 20 individuals with webbed feet and 180 individuals with the dominant trait of non-webbed feet. What are the frequencies of webbed feet and non-w
Two pigs whose tails are exactly 25 cm in length are bred over 10 years and they produce 96 piglets with the following tail lengths: 6 piglets at 15 cm, 25 at 20 cm, 37 at 25 cm, 23 at 30 cm, and 5
fur color in rabbits is determined by a single gene locus for which there are four alleles. Four phenotypes are possible: black, Chinchilla (gray color causes by white hairs with black tips), Himala
I believe the answer to this problem is 1/200 females are colorblind. I found the following on the internet: using the information below I determined an approximate incidence to be 1/192.
How does the idea of a lottery apply to your genetic makeup and its expression? In what way? Or does it apply.
A third gene pair on a separate autosome determines whether any color will be produced. The CC and Cc genotypes allow color according to the expression of the A and B alleles. However, the cc genoty
In humans, the ABO blood type is under the control of autosomal multiple alleles. Red-green color blindness is a recessive x-linked trait. If two parents who are both type A and have normal vision p
In cats, yellow coat color is determined by the b allele, and black coat color is determined by the B allele. The heterozygous condition results in a coat pattern known as tortoiseshell.
Each mating results in one of the five offspring shown to the right (a-e). match each offspring with one correct set of parents, using each parental set only once. Is there more than one set of corr
