Now, Danielle wants to know how her twins could look so diffe skin and Michael Jr. having dark skin. First, Danielle neede types of twins. Identical twins have exactly the same genes, since in a developing embryo splits into two embryos. Part III: Why do the twins look so different? er twins could look so different, with Michelle having light dark skin. First, Danielle needs to understand that there are two exactly the same genes, since identical twins originate when...

3. Application of DNA gel electrophoresis. DNA gel electrophoresis is commonly used in determining familial relationships among individuals, for ex; to establish paternity of a child. This technique is called DNA fingerprinting. In this technique the DNA of parents and children is roughly chopped up into pieces and resolved on an agarose gel. The DNA ill resolve according to their sizes and create a pattern or a "fingerprint". The fingerprint of the child is...

3. Which of these is/are true in DNA replication? 1. Helicase produces replications forks. 2. New histones are imported into the nucleus shortly after replication is complete. 3. DNA polymerase moves along a replication fork, making a new DNA molecules. 4. At the completion of replication, two molecules of DNA made from free nucleotides are formed.

1. the genes that seem to be the most necessary to maintain, since they are present in the smallest cellular organisms are a. cytoskeletal protein genes b, translation protein genes c. replication protein genes d. transcription protein genes e. DNA repair protein genes 2. Why do cellular organisms generally look very similar when early embryos but different from each other when mature? a. their DNAs have different chemistry b. their RNAs are different lengths c. what genes get turned on...

Two identical twins who showed very similar methylation patterns when they were 4 years old show very divergent patterns at age 40. This divergence is most likely due to a different alternative splicing in the two individuals Ob different levels of histone acetyltransferase in the two individuals. Oc environmental differences that they experienced as adults. O d. different genomic imprinting in the two individuals. O e differences in their experiences in utero Suppose that a certain enzyme is synthesized whenever...

Problem 1: Most humans are trichromats, which means they have three different pigments in their eyes that are sensitive to three different parts of the color spectrum. Dichromats have only two such pigments and see fewer colors. The three pigments in trichromat animals, like humans, are coded for by opsin genes called sws, MWs, and LWS (which stands for short-, medium-, and long- wavelength sensitive. respectively). These genes have been duplicated many times in evolutionary history and in fact, the...

In 1994, Congress passed the DNA Identification Act which authorized the FBI to do 2 things: (1) create and maintain a national DNA database, and (2) establish standards for forensic DNA testing. Because the human genome is full of DNA tandem repeats and because they vary in the number of contiguous repeat units, it was decided to use tandem repeats to build the DNA database. In 1996, 13 loci were chosen to be the core short tandem repeats (STR) for...

1. Explain why, when PCR is used to amplify the same region of DNA from two different people, the size of the DNA fragment(s) generated may be different? 2. What characteristic of the DNA molecule makes it possible to use electrophoresis to separate DNA molecules by size? Explain why this characteristic is important for electrophoresis and what part of the DNA molecule creates this characteristic. 3. You are performing PCR. After four cycles of PCR, how many double-stranded copies of...
