Insulin production via genetic engineering is becoming increasingly common and is used to produce large amounts of the hormone for use in treatments. It involves introducing a gene into a host organism, such as bacteria or yeast that will produce the insulin protein when grown in a laboratory. The resulting insulin is then purified to …
What may be the reason for the difference in the colour of skin in people living various parts of the world ? The primary reason for the difference in skin colour among people living in different parts of the world is the amount of melanin pigment present in the skin. Melanin is a natural pigment …
What is the possibility for the birth of a male or female child? The gender of a child is determined by a pair of chromosomes (known as sex chromosomes) that are inherited from each parent. The possible combinations of sex chromosomes that can occur in a child are XX (female) or XY (male). Therefore, the …

What is the genetic mechanism that determines whether a child is male or female? The genetic mechanism that determines whether a child is male or female is referred to as sexual differentiation. This process is determined by a person’s sex chromosomes, specifically the X and Y chromosomes. A person’s sex is determined at conception, when …
Mutations are changes in the genetic material (DNA or RNA) of a cell. These changes can cause a variety of effects, from mild to serious, depending on the type and location of the mutation and the organism in which it occurs. Mutations can result in changes in the organism’s physical characteristics, the production of new …
Fertilization occurs when a sperm and egg fuse together to form a single cell called a zygote. During fertilization, the alleles from the mother and father combine to form a new organism. These combinations of alleles are known as genotypes and are responsible for the physical traits of the organism. Some of these traits are …

Crossing over is a process that occurs during meiosis and is responsible for producing genetic variation. During meiosis, chromosomes exchange genetic material, resulting in the formation of new combinations of alleles. Cross over occurs when two homologous chromosomes break and exchange sections of their DNA, creating a new combination of alleles and a new set …
The human genome consists of 23 pairs of chromosomes. 22 of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, are different between males and females. Females have two copies of the X chromosome, while males have one copy of the X and one copy of …
How do genes act? Genes act by providing instructions for the production of proteins which, in turn, control the development and functioning of cells, tissues, and organs. Genes are responsible for a wide range of physical and behavioural traits, including hair and eye colour, height, and personality. Genes can be altered by mutations, which can …
RNA is a type of nucleic acid that plays a role in a wide range of biological processes in all living organisms, including protein synthesis and gene regulation. RNA is made up of a single strand of nucleotides, which are molecules made up of a nitrogenous base, a ribose sugar, and a phosphate group. RNA …
