Mitosis A(n) _____ is the code for a protein. gene A(n) _____ sperm is formed during meiosis. haploid Budding is a type of _____. asexual reproduction A(n) _____ is a structure in the nucleus that contains hereditary material. chromosome _____ produces four sex cells. Meiosis An error made during the copying of DNA is called a(n) _____. mutation As different as a lizard, a great white shark, and an eggplant are, they are all made of _____. cells The series of events that take place from one cell division to the next is called the _____. cell cycle After interphase, _____ begins. a. cell death b. cell division c. cell consumption d. cell erosion B Cells in your body that no longer divide are always in _____. interphase The process in which the nucleus divides to form two identical nuclei is known as _____. mitosis In asexual reproduction, the new organism will have hereditary material that is ____ the parent organism. identical to All of the following are true of animal and plant cells during mitosis EXCEPT _____. a. only animals have spindle fibers only plants have rigid cell walls only plants form cell plates only animals have centrioles A All of the following are composed of body cells EXCEPT ____. a. bone b. kidney c. liver d. sperm D Each human skin cell has ____ pairs of chromosomes. 23 Human sex cells have ____ individual chromosomes. 23 In sexual reproduction, a new organism is produced when ___. a. cell divide by mitosis b. sex cells combine c. an organism divides into two equal parts d. a new organism grows from the body of its parent B In ____, a new organism grows from the body of the parent organism. budding The number of chromosomes in a sex cell of an organism is its ___ chromosome number. haploid At the end of meiosis, ___ cells have been produced from one cell. 4 Proteins are made of units called ___, which are linked together in a specific order. amino acids The code for making proteins is cared to the ribosomes by ___. mRNA In DNA, adenine always pairs with ___. thymine For most cells, after the nucleus has divided, ___ separates and two new cells are formed. cytoplasm During prophase, the pairs of ____ are fully visible when viewed under a microscope. chromatids Organisms with eukaryotic cells asexually reproduce by ____. cell division The cell that forms as a result of fertilization is known as a _____. zygote Because sex cells do not have pairs of chromosomes, they are said to be ____. haploid Before mitosis begins, each ____ is duplicated. chromosome True/False Regeneration is the process that uses cell division to regrow body parts. True During asexual reproduction two sex cells, sometimes called an egg and a sperm, come together. False sexual reproduction Sex cells have half the number of chromosomes as body cells. True Haploid sex cells are produced by a process called meiosis. True Organisms with three, four, or more sets of chromosomes are known as haploid organisms. False polypoid Every cell that has ever been formed in your body, or in any other organism’s body, contains DNA. True DNA stands for deoxyribonucleic acid. True RNA is made in the nucleus on a DNA pattern. True Sex cells have half the number of chromosomes that body cells have. True Haploid sex cells are produced by meiosis. True Organisms with three sets of chromosomes are known as haploid organisms. False triploid Multiple Answers Lists the phased of Mitosis in order. prophase, metaphase, anaphase, telephase List the types of RNA. (you may not use the abbreviations) List the nitrogen bases. adenine thymine cytosine guanine
