What is the best description of 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 description of a chromosome quizlet?
Chromosome : a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes. Trait : A characteristic that an organism can pass on to its offspring through its genes.
How would you describe chromosomes in your own words?
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.
What describes a human chromosome?
= 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.
Which of the following is the best description of a gene?
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
Which of the following is the best definition or description for chromatid?
A chromatid is an individual strand (DNA molecule) in a replicated chromosome.
What is the best description of mitosis?
Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
Which of the following statement is the best description of the cell cycle?
Answer: A cell cycle is a series of events that takes place in a cell as it grows and divides. … The cell then leaves interphase, undergoes mitosis, and completes its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle.
Which of the following is the best description of the cellular components Glycosomes?
Which of the following is the best description of the cellular components glycosomes? They store sugar in the form of glycogen and contain enzymes to degrade glycogen into its glucose subunits.
What do chromosomes tell us?
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. … Your chromosomes describe what color eyes you have, how tall you are, and whether you’re a boy or a girl.
What is a chromosome easy definition?
(KROH-muh-some) A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.
Who described chromosome?
‘ It’s generally recognized that chromosomes were first discovered by Walther Flemming in 1882.
What does each chromosome do?
Each one of our cells contains 23 pairs of chromosomes; one of the chromosomes comes from our mother and the other from our father. Like a recipe book, each chromosome contains a certain number of recipes, known as ‘genes’. Over 20’000 genes are recipes for proteins which are essential components of life.
What is chromosome structure and function?
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.
