Essay On Protein Synthesis

All living things contain DNA. The molecule deoxyribonucleic acid or DNA is what contains an organism’s genetic information. The genetic information contained in DNA is what an organism requires to not only develop and reproduce but also survive. A DNA molecule is built up of nucleotides. Nucleotides are composed of several different things and what the nucleotides are composed of determines the name of it. Another job of DNA is to pass the genetic information through the process of protein synthesis. The DNA can show birth defects in the fetus using different testing. The knowledge of the birth defects of the fetus can be both positive and negative. DNA is a simple yet complex molecule that is used by all living things and makes us the way

Protein synthesis consists of two main steps: transcription and translation. The DNA is found inside of the nucleus and there in the nucleus a copy of one side of the DNA strand is made, this is the messenger RNA or mRNA. After this the mRNA travels through the cytoplasm with the DNA copy and arrives at the ribosomes. The mRNA then goes through the ribosome three bases at a time. A transfer RNA molecule or tRNA then bring the correct amino acid to match the codon. The amino acids then link together to form a long chain of proteins, making amino acids the building blocks of

Prenatal DNA testing for birth defects itself is very good and beneficial for the parents. What the parents decide to do with the knowledge though is where it can become negative and a bad thing. If you decide to have the prenatal DNA testing done and you find out that your child is going to be born with Down Syndrome you will then have decide to if you are going to continue the pregnancy or not. If the parents decide to have an abortion the moral ramifications of this are the parents might feel guilt or regret for killing an innocent unborn child or they might be relieved that they do not have to raise what they might consider a burden. This is one way prenatal DNA testing can be negative but there are also ways it can be positive because not everyone decides to have an abortion. If parents decided to keep the baby they can prepared for the baby and the lifestyle they will have. The parents could speak to other parents who have raised a child with Down Syndrome and the parents will feel prepared and happy with their choice to bring their beautiful child into the world. These test can go both ways, you can find out that you are going to have a healthy baby but waiting for your results can also bring unnecessary stress and worry which is also not good for the baby. In the end the moral ramifications of the tests are determined by what you do with
