Question 1: Describe the control of gene expression In the Andalusian fowl, the allele for black feathers (B) is incompletely dominant to that for white feathers (b) and the phenotype of the heterozygote is described as blue. The texture of the feathers is controlled by a second gene locus, silky feathers (f) being recessive

The Planning, Research and Development, Corp. is seeking grant money to continue their investigation on the relationship between DNA and heredity. You want it apply for the grant money to continue your internship research project. You thought it would help your case if you research projects where DNA research is being applied wi
Discuss transcription, including such things as the location in the cell, transcription signals, products, chemical details, and/or the amount of chromosome involved.
I have not clue where to start on this or how to go about it. Apart from its essential role in cellular respiration, the mitochondrion is thought to be implicated in a variety disease states as well as the process of ageing. The mitochondrion contains its own circular DNA molecules (termed mtDNA) which largely encodes for pr
F1 females from a cross of AABBCC to aabbcc were backcrossed to aabbcc males. IN the progeny of this cross there were 150 AaBbCc, 145 aabbcc, 55aabbCc, 52 AaBbcc, 31 aaBbcc, 29 AabbCc, 5 Aabbcc and 3 aaBbCc. Is there evidence of interference? What is the coefficient of coincidence?
Rarely, hens reverse phenotypic (not chromosomal dew late in life and develop into sprem producing males. If such a male were to be mated to a normal female, what sex ratio would be expected among the offsrping? (Eggs with no X chromosome do not hatch.)

They are? 2) In the process of making a protein, the purpose of an adaptor is to? 3) An allosteric receptor embedded in a cell membrane will change shape only when? 4) When the repair mechanism for DNA fails, the result is a what? 5) In the telophase
(see diagram in the attached file) Answer the following questions based on the assumption that genotypes BB and Bb have brown eyes, while bb has blue eyes. Filled in the symbols in the pedigrees that represent blue eyes. a) What is the probability that the first child of a mating between II-2 and II-7 would be a blue-eyed
Imagine that you find a sequence 5' GTTTCA 3' at one end of a transposable element. a) Draw this sequence as an inverted repeat on both ends of the element (filling in the N's in the following format): 5GTTTCA-------------------------------NNNNNN3 3CAAAGT------------------------------NNNNNN5 B) draw this sequence as a dire
You are attempting to map the restriction sites for Ecor I and BamH I on a circular DNA molecule. After conducting single digests with Ecor I and BamH I as well as a double digest, you obtain the following data: Ecor I BamH I Ecor I + BamH I fragment 1 8000bp 2500 bp
You would like to amplify a stretch of DNA with the following sequence using the polymerase chain reaction: 5' GTGTTTAGTGGGCGGTAACCGTTACGTAGGTAATGCT 3' Assume (unrealisitcally) that you will use 5 nucleotide long primers positioned to amplify the entire sequence. a) What are the sequences of the two primers you would use?
Eukaryotes may regulate gene expression at any number of levels. Imagine that transcripts of gene A are found only in the developing liver and transcripts of gene B are found only in the developing eye. List a general type of cis-regulatory sequence difference that could explain the expression difference between the two genes

Question: You are given a mutant cell that lacks the GTPase activating protein. What abnormalities would one expect to find in the way that RAS activity responds to extra-cellular signals? Why?
In a series of experiments, genes that code for mutant forms of a receptor tyrosine kinase are introduced into cells. The cells also express their own normal form of the receptor from their normal gene, although the mutant genes are constructed so that they are expressed at considerably higher concentrations than the normal gen
