1. A homozygous red-eyed female Drosophila mates with a red-eyed male Drosophila. What proportion of the female offspring will have white eyes?75%25%100%0%2.Red-green colorblindness is a recessive X-linked trait. If a female is red-green colorblind, which of the following is TRUE?Her father must be colorblind.Both her parents are carriers of the recessive allele.Both her parents must be colorblind.Her mother must be colorblind.Women cannot exhibit red-green colorblindness because they have two X chromosomes.3.Alleles arerecessive traits.dominant traits.exact copies of the same trait.alternate versions of the same trait4.Using three bases to represent each amino acid in a polypeptideensures that other organisms can read the code too.prevents the wrong amino acid from being incorporated into a protein.ensures that DNA can replicate properly.ensures that all amino acids are represented at least once by the code.5. If an organism's DNA contains 20% adenine nucleotides, what percentage of its DNA is composed of guanine nucleotides?15%10%30%40%6. A true-breeding tall pea plant is crossed with a tall pea plant of unknown parentage. Which of the following is correct?Some short individuals may appear in the F2 generation.Some of the F1 generation will be short.All of the offspring (F1) will be short.Over several generations, no short individuals will appear.7.Morgan breeds and sells snakes. He knows that he can make the most money by breeding and selling albino snakes. Albinism is a recessive trait. His female albino corn snake just produced 6 offspring. Two displayed normal coloration and 4 were albino. What do you know about the genotype of the father?He could be either heterozygous or homozygous dominant.He must be homozygous recessive.There is not enough information to determine the father's genotype.He must be heterozygous.8.During the elongation cycle of translation, the A site on a ribosome functions inreleasing the completed polypeptide.holding a polypeptide as amino acids are added.attaching the small subunits of rRNA to the large subunit.receiving a new tRNA with the correct amino acid.9.Which of the following is an incorrect match?translation - polypeptide formationtranscription - tRNA formationtranslation - mRNA binding to rRNAreplication - copying of DNA10. The three steps that are required for DNA replication arebase doubling, unwinding, and joining.unwinding, base doubling, and base pairing.unwinding, complementary base pairing, and joining.unwinding, transcription, and translation.11.The x-ray diffraction pattern of DNA discovered by Rosalind Franklin showed that DNAcontains alpha helices and beta sheets.contains beta sheets arranged in a repeated pattern.has a repeated pattern.is both helical and has a repeated pattern.12. Which of the following is TRUE?All traits on the sex chromosomes are associated with sexual development.Females can be heterozygous for sex-linked traits.Males are heterozygous for the SRY gene.Men pass their X-linked traits to their sons.13. Martha has a widow's peak and attached earlobes. Martha's dad had a straight hairline and unattached earlobes. What is Martha's genotype?WweeWwEEwweeWWEE
What happens to the post-synaptic cells' membrane potential at an inhibitory synapse?define why the coupling of the import of amino acids.
Determine what type of information is provided by the RBC indices and discuss h ow statistically relevant is this information?
Assume that a disease is inherited via a dominant mode of inheritance and that one of the parents is affected with the disease and the other is not.
Examine the major stages of sea urchin development with reference to your series of detailed drawings and observational notes. How did the embryonic cells compare in size with the original gamete cells? State reasons such a difference may exist.
They have one child. What is the possibility that their child will have the disease. 52 dark moths and 21 light moths were at random recaptured. Which would be the most reasonable assumption.
In some cases the first gene in the linear sequence appears to be transcribed at a much higher rate than the second and subsequent genes (as in many but not all mRNAs contain the sequences encoded by gene 2 and beyond).
One of the major categories of receptors in the plasma membrane reacts by forming dimmers, adding phosphate groups, and then activating relay proteins. Which kind does this.
How can the photosynthesis process be enhanced to fix more CO2 than normal and plant productivity could be increased.
The seeds of orchids are among the smallest known, with virtually no endosperm and with miniscule seed leaves. As a result, what must one expect to be true of such seeds.
A series of enzymes catalyze the reaction X Y Z A. Product A binds to the enzyme that converts X to Y at the position remote from its active site. This binding decreases the activity of the enzyme.
What is the difference between heterosporous and homosporous plants? What two types of spores do heterosporous plants produce? Spores that will develop into a female gametophyte are.
Describe b riefly the role of HOX genes in brain development. If a twenty-five year old woman using Accutane to treat acne discovers that she is pregnant, what concerns do you have for the embryo/fetus?
