The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

nucleus

The nucleus directs all cellular activities by controlling the synthesis of proteins. The nucleus contains encoded instructions for the synthesis of proteins in a helical molecule called deoxyribonucleic acid (DNA). The cell’s DNA is packaged within the nucleus in a structural form called chromatin.

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.

Transcription factors are proteins that control the production of other proteins. Enzymes involved in the same pathway in the cell are often controlled by the same transcription factor. Promoters are the sequences of DNA that determine when a gene is expressed.

However, the gene expression level is a primary process that determines, controls, and directs protein production.

The liver is one of the most important organs for making proteins. It produces or transforms millions of protein molecules each day. Proteins are made from amino acids.

proteins control the characteristics. Heredity is the passing of genes from one generation to the next. Genes hold the instructions for making protein products (like the enzymes to digest food or the pigment that gives your eyes their color). As your cells duplicate, they pass this genetic information to the new cells.

Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.

Most traits are determined by more than one gene. For example, skin color and height are determined by many genes….

• Interlocking fingers. Interlock fingers.
• Ear lobes.
• Widow’s peak.
• Tongue curling.
• Hitch hiker’s thumb.
• Pigmented iris.
• PTC tasting.

The genes present in the DNA control characteristics or traits. The phenotypic or physical expression of a character depends upon the genotypic constitution. The expressed traits are a result of the specific genotypic combination of the alleles, which are a pair of genes . This is how genes control the traits.

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

Birds, insects, animals, trees, human beings, are a few examples of living things as they have the same characteristic features, like eating, breathing, reproduction, growth, and development, etc.

Answer and Explanation: What an organism looks like is their phenotype. An individual’s phenotype is based on their genotype, which is their genetic makeup. We inherit our genes from our parents, and we often have many physical traits in common with them.

Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

Your DNA contains a record of your ancestors, but you aren’t a carbon copy of any one of them. The particular mix of DNA you inherit is unique to you. You receive 50% of your DNA from each of your parents, who received 50% of theirs from each of their parents, and so on.

Genes come in different varieties, called alleles. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism’s offspring and expressed in a later generation.

The Hidden Trait Every Leader Needs And How To Get It

• Completeness. You are connected to your true self.
• Humility. You recognize that success is never a solo effort; that whatever level of status and success you have today is because others have contributed to your development.
• Pain.
• Restlessness.
• Optimism.

An organism receives two genes for each trait, one from each parent. The trait of the weaker gene is “hidden” or does not show up and is called the recessive gene.

Genes are the factors that control Traits. Alleles are the different forms of Genes. Individual Alleles control the inheritance of Traits.

To summarize, two things determine the traits an organism has: its genotype and the dominance or recessiveness of the alleles it has. Some traits, like flower color in peas, are controlled by a single gene, but ultimately many if not most traits in an organism are controlled by more than one gene.
