What is DNA in your own words?

What is DNA in your own words?

Your DNA is what makes you uniquely you. It’s that double helix that your genes are made of. DNA stands for deoxyribonucleic acid, sometimes called “the molecule of life,” as almost all organisms have their genetic material codified as DNA.

What is DNA in simple words?

DNA or deoxyribonucleic acid is a long molecule that contains our unique genetic code. Like a recipe book it holds the instructions for making all the proteins in our bodies. Your genome? is made of a chemical called deoxyribonucleic acid, or DNA for short.

What is chromosome in your own words?

A chromosome is a strand of DNA that is encoded with genes. The word chromosome was originally coined in German from the Greek words khroma, meaning color, and soma meaning body.

What is a chromosome like in real life?

What are chromosomes? Chromosomes are tiny structures inside cells made from DNA and protein. The information inside chromosomes acts like a recipe that tells cells how to function and replicate. Every form of life has its own unique set of instructions, including you.

What is a chromosome short answer?

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique

Which are the two main parts that make up a chromosome?

DNA is coiled around proteins called histones, which provide the structural support. Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division. Each chromosome has a centromere, which divides the chromosome into two sections – the p (short) arm and the q (long) arm.

How small is a chromosome?

Chromosome size estimates from various strains range from 2.0–3.1 Mbp. Physical and genetic maps have been constructed for two L. lactis subsp.

What is the basic principle of genetics?

1. that the inheritance of each trait is determined by “units” or “factors” that are passed on to descendents unchanged (these units are now called genes )
2. that an individual inherits one such unit from each parent for each trait

What can genes tell us?

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.

Do we all have the same genes?

Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features

Do siblings have the same DNA?

Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says. So while biological siblings have the same family tree, their genetic code might be different in at least one of the areas looked at in a given test. That’s true even for fraternal twins

Do brothers and sisters have the same blood type?

Each biological parent donates one of their two ABO alleles to their child. Identical twins will always have the same blood type because they were created from the same fertilized egg (fraternal twins can have different blood types — again, providing the parents do — because they are created by two fertilized eggs).

What blood type lives the longest?

Life Span. Chances are higher you’ll live longer if you have type O blood. Experts think your lowered risk of disease in your heart and blood vessels (cardiovascular disease) may be one reason for this

What is oldest blood type?

There are four main blood types. Blood type A is the most ancient, and it existed before the human species evolved from its hominid ancestors. Type B is thought to have originated some 3.5 million years ago, from a genetic mutation that modified one of the sugars that sit on the surface of red blood cells
