7. The figure to the right shows that injection of M-phase cytoplasm into an oocyte triggers the cell to enter mitosis. What would be the expected effect on cell division if cytoplasm from a G2-phase cell were injected into an M-phase cell? A. DNA replication would begin again. B. activation of all cyclin-CDK complex in the cell.
3. Describe each stage of the flow of information starting with DNA and ending with a trait. Information will start with the DNA traveling to the RNA and into the protein. This information flow will also be followed through the cell as it travels from the DNA in the nucleus, and the Cytoplasm, then to the Ribosomes and the Endoplasmic Reticulum, and finally to the Golgi apparatus, this system packages the final products for export outside the cell (Science Daily, 2013).

Every child inherits genes from both of their biological parents and these genes in turn express specific traits. Some of these traits may be physical for example hair and eye color and skin color etc. It’s what makes us up, who we are! Genes are the instructions that tell our cells what to do. Mutations in these genes alter cell behavior, often with harmful effects.
Other types of mutations in DNA can occur when small part of DNA break off the chromosome. These pieces of DNA may introduced in another region in the chromosome and affect the usual translation of information. This type of mutation can affect coding for specific amino acids, which can affect the type of protein formed, which can alter cellular and organismal function. The most common type of mutation are base pair substitution and insertion and deletion mutation. In substitution mutation one base is substitutes another base in the pair.
Some ideas and theories in science meet with resistance. One of the examples when an idea is meeting with the resistance is immunization. More often children immunization meets with public resistance. As the vaccination of children is parents' decision many decides not to do it. Data published by NHS show that there is high number of measles reported due to 1-16 years old children who missed the vaccinations between 1990s and 2000s.
All cells run on a set of instructions spelled out in DNA DNA ! Cells ! Bodies ! How does DNA code for cells & bodies? " how are cells and bodies made from the instructions in DNA Regents Biology!
A ribosome can also be known as the chemical factory. Messenger ribonucleic acid (mRNA) has the job of making copies of parts of the DNA as required by the body and taking it through the chemical factory. So in relation to the topic of this essay, a messenger mRNA comes along and takes a copy of a digestive enzyme from the DNA and squeezes through the pores with it into the cytoplasm . In this environment it heads towards the ribosomes and passes through the ribosome where protein synthesis and translation occurs. The protein then passes to the Golgi apparatus where it is processed and packaged or more simply modified and labelled for its digestive function then released in vesicles to go and perform its specific function.
It is not always good to take too much medication because of the side effects it can cause later on, and sometimes even instantly. Pediatric Polypharmacy becomes a problem because the current prescribing practices are based on adult research, and they are not completely aware of how it was affect children. I believe that more thorough research needs to be done before prescribing them , or new medications needs to be discovered that can be used for children with psychiatric problems. Doctors need to stop prescribing multiple medicines, if they are they need to explain the side effects it can cause and clearly state the pros and cons of taking the different medications. This way they will be following some ethical
Access to recreational facilities, access to health and social care services, bullying, family dysfunction, effects of culture, religion and beliefs, effects of discrimination; Socioeconomic, e.g. income, expenditure, education, values and attitudes, peer groups, employment status; Lifestyle, e.g. nutrition and dietary choices, alcohol Intake, use and misuse of substances The different life factors that can affect the development of an individual are * Genetic * Environmental * Lifestyle * Biological * Socioeconomic Genetic Genes are made out of DNA (deoxyribonucleic acid) which knows and understands how to produce proteins. These proteins are used for human development, even though in a living cell of a human body there are 23 pairs of chromosomes. Each pair of chromosomes includes one chromosome from the mother and one from the father, but your genetic pattern and development may be very different to your parents.
If this happens it would also prevent the neurons from communicating using dendrites and axons. Neurotransmitters and the process of synapses would possible be completely destroyed. If I were to educate young adults and caregivers in the effects of Shaken Baby, I would explain in great detail the possible consequences because of the damages. I would explain to the parents and caregivers that the syndrome can cause permanent disabilities to the infant such as partial or total blind, cerebral palsy, learning difficulties, and more. Not only would I verbally tell the parents about such, but showing them photos would give them a more realistic view that it could possibly happen to their infant if not treated with care.
