Quick Answer: What Is A Chromosome Short Answer?

Which is the female chromosome?

Typically, biologically female individuals have two X chromosomes (XX) while those who are biologically male have one X and one Y chromosome (XY).

However, there are exceptions to this rule.

Biologically female people inherit an X chromosome from their father, and the other X chromosome from their mother..

What’s another word for chromosome?

Synonyms for chromosomeRNA.gene.heredity.genetic code.nucleic acid.

What is a chromosome and what is its function?

Function of a Chromosome The chromosome holds not only the genetic code, but many of the proteins responsible for helping express it. Its complex form and structure dictate how often genes can be translated into proteins, and which genes are translated.

What are the 4 types of chromosomes?

There are four main types of chromosomes: metacentric, submetacentric, acrocentric, and telocentric. Chromosomes are found within the nucleus of most living cells and consist of DNA that is tightly wound into thread-like structures.

What is the main function of chromosome?

Chromosomes are thread-like structures present in the nucleus, which carries genetic information from one generation to another. They play a vital role in cell division, heredity, variation, mutation, repair and regeneration.

Who use the word chromosome?

The term ‘chromosome’ was first suggested in 1888 by the German anatomist Waldeyer. He used the term to describe certain structures that form during the process of cell division.

What is a chromosome easy definition?

A chromosome is a strand of DNA that is encoded with genes. In most cells, humans have 22 pairs of these chromosomes plus the two sex chromosomes (XX in females and XY in males) for a total of 46. The word chromosome was originally coined in German from the Greek words khroma, meaning color, and soma meaning body.

What is chromosome in human body?

A chromosome is an organized package of DNA found in the nucleus of the cell. Different organisms have different numbers of chromosomes. Humans have 23 pairs of chromosomes–22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y.

Is YY a girl?

Biological sex in healthy humans is determined by the presence of the sex chromosomes in the genetic code: two X chromosomes (XX) makes a girl, whereas an X and a Y chromosome (XY) makes a boy.

What is an XY female?

Protein SRY. Specialty. Medical genetics. XY gonadal dysgenesis, also known as Swyer syndrome, is a type of hypogonadism in a person whose karyotype is 46,XY. They typically have normal female external genitalia, identify as female, and are raised as girls.

What is difference between DNA and chromosome?

Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person’s genes.

What is a chromosome example?

Chromosome definitions The definition of a chromosome is a thread-like structure of DNA (nucleic acids and proteins) that carries genes. The “X” or “Y” gene that determines whether you will be a boy or a girl is an example of a chromosome.

What are chromosomes kid definition?

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 chromosome with diagram?

The chromosome is the condensed and compactly arranged structure of the DNA with the help of histone proteins H1, H2A, H2B, H3 and H4. This is the structure which can be visible during the metaphase of cell division. This condensed packing allows the long DNA in the eukaryotes to be packed in the nucleus of the cell.

What are the basic parts of a chromosome?

It turns out that chromosome can be divided into three different parts: the centromere, the arm and the telomere. Notice that the chromosome is often depicted as an X-shaped structure with a constriction in the middle.

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

DNA and histone proteins are packaged into structures called chromosomes.

How do you describe a chromosome?

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.

What is the best definition of a chromosome?

Medical Definition of Chromosome Chromosome: A carrier of genetic information that is visible under an ordinary light microscope. … Generally the nucleus of a human cell contains two sets of chromosomes’one set given by each parent. Each set has 23 single chromosomes: 22 autosomes and an X or a Y sex chromosome.
