3-2-1 Assignment- Genetic Inheritance 3 Main Points: 1. The cell contains three important things. Those three things are the nucleus, mitochondria, and the ribosomes. The nucleus consists of DNA and RNA molecules which contain hereditary information that has a jurisdiction of the cell’s purpose. The mitochondria contains mtDNA distinctive influence in human developmental research. Lastly, the ribosomes are the basic necessity to the process of protein synthesis. 2. Meiosis is a process where…

1. James Watson and Francis Crick were credited for discovering the double helix structure of DNA molecule. James Watson is known to have received his degrees at the University of Chicago and his PHD at the University of India. He then met Francis Crick at the University of Cambridge where he later worked after receiving his PHD. Francis Crick during the World War II was some biophysics who held develop radar and magnetic mines then after the war he then began the structure of DNA research with…

1. Francis Crick Crick discovered the relative distances of the repetitive elements in the DNA molecule, and the dimensions of the monoclinic unit cell which indicated that the molecule was in two matching parts, running in opposite directions. He also, in collaboration with Watson discovered the material that our genes are made of and put forward the model of the double helix DNA structure which included the measurements of the angels formed by different chemical bonds. Crick in collaboration…

problem with this particular method is that it is not only time consuming and not only is it ineffective but it also limits the size of that gene that we can actually use. A much more effective and much more efficient and accurate method is the Polymerase Chain Reaction. This method allows us to amplify a certain sequence of DNA very quickly…

Figure 2. The proteomic organization of three subfamilies of Smads (Co-Smad, R-Smad and I-Smad) and organization of a Smad MH1 domain with DNA. (A) All Smads information taken from PDB entry Smad>UniProt Gene list of Smads. The conserved N-terminal MH1 domain is in red, linker region in dark blue and the C-terminal MH2 domain in deep yellow. In the linker region the red PXS/TP (or S/TP) indicates the potential phosphorylation site for MAPKs ERK1/2, and the square indicates the PY…

Deoxyribonucleic acid is known as the molecule of inheritance where its structure dictates its function in storing the genetic information of the organism (Rafael, 2010). This molecule contains genes which encode proteins needed for the complex biochemical metabolic reactions which occur within the organism (Rafael, 2010). The DNA molecule consists of 2 complementary strands in a helical structure where each strand serves as an informational template for the offspring during duplication (Rafael,…

A. Polymerase chain reaction (PCR) Principle It includes the primer mediated enzymatic amplification of DNA. It uses the ability of DNA polymerase to manufacture new strand of DNA complementary to the offered template strand. DNA polymerase can add a nucleotide only onto a preexisting 3′-OH group to add the first nucleotide that is way Primer is required. Then DNA polymerase elongates its three ends by adding more nucleotides to generate an extended region of double-stranded DNA.…

Recombination and mutation are the motivation of evolution. Recombination is critical for repairing DNA lesions and for chromosomal pairing, and exchange during meiosis (Krejci et al. 2012). Recombination does not occur uniformly on the chromosomes of eukaryotes. Meiotic recombination in well studied yeast revealed that non-uniformity of recombination was observed when the frame of reference is an entire chromosome, multigene region and a pair of genes or a small region upstream of a gene…

All cell organisms have this chain of nucleotides that give them a unique coding that helps everything differ from one another. Whether within plant or animal cells, these coding strands contain our genetic information. The creation of our genetic codes derives from a mixture of our parent genetic codes. These codes we contain are called DNA, also known as deoxyribonucleic acid. These DNA strands carry all our information. Skin color, eye color, body shape, hair type, etc. This creates us…
