Take for example a fetus of 2 weeks old and a baby of 2 years old. The fetus doesn't show any limbs, skull. How do I know that is a human fetus ?
Thanks Ryan_M_B.Ryan_m_b said:DNA testing would reveal what species it is. I have to ask though under what circumstances do you envision being given a random embryo and asked to identify the species?
Gene expression is the process by which information from a gene is used to create a functional gene product, such as a protein. It involves the transcription of DNA into RNA, which is then translated into a specific protein.
Gene expression plays a crucial role in determining the size and shape of limbs. Certain genes are responsible for controlling the growth of limbs and their development. Changes in the expression of these genes can lead to variations in limb size and shape.
Several factors can influence gene expression for bigger limbs, including genetics, environmental factors, and epigenetics. Genetic variations, such as mutations or polymorphisms, can affect the expression of genes involved in limb development. Environmental factors, such as diet and exercise, can also impact gene expression. Epigenetic changes, which alter how genes are expressed without changing the underlying DNA sequence, can also play a role in limb size.
Scientists study gene expression for bigger limbs using a variety of techniques, including gene expression analysis, genetic engineering, and animal models. Gene expression analysis involves measuring the levels of gene expression in different tissues or under different conditions. Genetic engineering allows scientists to manipulate gene expression and study its effects. Animal models, such as mice or zebrafish, are often used to study gene expression in the context of limb development.
Yes, gene expression for bigger limbs can be manipulated through various methods, including gene therapy, gene editing, and drug treatments. These techniques aim to either increase or decrease the expression of specific genes involved in limb development, ultimately leading to changes in limb size and shape. However, more research is needed to fully understand the complexities of gene expression and its impact on limb size before these methods can be used in a safe and effective manner.
