Chromosomal location: 11p15.5 (tyrosine hydroxylase, 1st intron) Repeat motif: TCAT (GenBank top strand) although AATG (bottom strand) often used. Note that variants with a [AATG]nATG[AATG]n structure quite common e.g. [AATG]6ATG[AATG]3 would be 9.3 repeats. Allele range: 3-14

Help with Identificatying Restriction Enzyme Recognition Sites in a DNA sequence
Hi Folks,
I'm really struggling with a PCR & restriction enzyme question that's part of my formative (unmarked) work for the summer months in preparation from an Applied Biology course at University.
The entire set of questions are set out on an instruction sheet so I'll try to replicate them here as I'm struggling to fully understand ho

Once elongation is underway, tRNAs involved in the process occupy a series of sites on the complexed ribosome. The occupation of sites occurs in the following order.
translate this into protein using the genetic code table.
Below is a sequence of double stranded DNA from a bacterium. Based on what you know about bacterial transcription and translation, put an “X” next to the strand that is most likely to be the template strand for transcription and give a brief answer for your choice (5-10 words). Then, • clearly underline the likely coding sequence • transcribe it into mRNA
Indicate whether each of these is plesiomorphic (ancestral) or apomorphic (derived) in the great ape lineage, using the phylogeny below. Great apes include orangutan, gorilla, chimp, and human.
A scientist wanted to compare the evolution of the families Balaenopteridae (the rorqual baleen whales) and Delphinidae (the dolphins). Balenopteridae consist of about 11 species while Delphidae consist of about 41 species. The scientist proposes the hypothesis that evolution has occurred more rapidly in Delphinidae due to their active, predatory lifestyle, while the baleen whales,

Where does the cut take place in palindrome sequence
In the case of restriction enzymes, I know that it chooses Palindromes, but where does the exact cut take place? Is it always between A and T base pairs or Can it occur between any base pairs in a palindrome sequence.
Theodore was a highly inbred handsome rat with a very long tail (30 cm), while his equally inbred yet striking mate, Spacey, had a petite tail (6 cm). When Theodor and Spacey had their first litter, all had 18-cm tails. When the babies grew up and interbred, they produced 256 F2’s with tails ranging in size from 6 cm to 30 cm in the following intervals: 6, 10, 14, 18,

A cross was made to produce D. melanogaster flies heterozygous for two pairs of alleles: A and a, which determine long versus short wings, and B and b, which determine gray versus ebony body color. The following F2 data were obtained: Long wing, gray body 240 Long wing, ebony body 40 Short wing, gray body 40 Short wing, ebony body 80 Test
Consider a diploid cell where 2n = 6. During metaphase I of meiosis, as the pairs of homologous chromosomes line up on the metaphase plate, each pair may orient with its maternal or paternal homolog closer to a given pole. There are four equally probable arrangements of the homologous pairs at metaphase I. (Note that this problem assumes that no crossing over has occurred.)
Ok no matter how many times i am explained this it makes no sense and its not in the book i use so i have nowhere to turn, can anyone help me understand whats happening with these plates it looks like a bunch of dots to me i don't see how its getting those genotypes from the given information.
I can't figure out how to do the punnet square for any of this or what it all means? Can anyone please explain how to understand the solution? Looks like a bunch of letters and numbers to me.

Distance between shine delgarno and start codon affecting mRNA requirement?
Here's a question that I can't seem to grasp.
There are two mRNAs presented in the 5' to 3' direction, one of which belongs to strain A and the other one belonging to strain B.
Strain A's shine delgarno is further away from the AUG start codon (~17nucleotides) Strain B's shine delgarno is optimal distance from the AUG start co
Fly larva mutations for Gap, pair-rule, and maternal effect genes
The title say most of it. I'm supposed to draw the mutations in the Drosophila larva, but I also need to label the structures which my textbook is not helping me much with. So far I just know that the mutants are stubby little creatures... I also need to list the specific gene mutated since I guess these are gene families???

The first two pregnancies for a couple result in late term stillbirths. The reproductive histories of both families, over 3 generations, were compiled. A pattern of frequent miscarriages, stillbirths and malformed babies that died shortly after birth were seen in the husband's family. The husband has a karyotype done, which shows that he has the normal number of chromosomes. Wh

In a transformation experiment, donor DNA was obtained from a prototroph bacterial strain (a + b + c +), and the recipient was a triple auxotroph (a − b − c −). What general conclusions can you draw about the linkage relationships among the three genes from the following transformant classes that were recovered? a+ b- c- 180 a- b
Two theoretical genetic strains of a virus (a − b − c − and a + b + c +) were used to simultaneously infect a culture of host bacteria. Of 10,000 plaques scored, the following genotypes were observed. Determine the genetic map of these three genes on the viral chromosome. Decide whether interference was positive or negative. a+b+c- 41000

Hello!
I was wondering if someone can explain how to solve a lac operon problem? The attached picture is the one from our problem sets and the answers are right, I just don't understand how to get the answers.
The likelihood of having identical children (who are not twins)
So I figure if you have enough babies (probably in the billions) you'd eventually get one that was essentially genetically and/or aesthetically identical to another. Could anyone give me any background information and numbers regarding the likelihood of this?
