In biology, cloning is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects, plants or animals reproduce asexually. Cloning in biotechnology refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms (organism cloning). The term also refers to the production of multiple copies of a product such as digital media or software.
The term clone, invented by J. B. S. Haldane, is derived from the Ancient Greek word κλών klōn, "twig", referring to the process whereby a new plant can be created from a twig. In horticulture, the spelling clon was used until the twentieth century; the finale came into use to indicate the vowel is a "long o" instead of a "short o".Since the term entered the popular lexicon in a more general context, the spelling clone has been used exclusively.
Answer:
Answer is option A (true).
The child has brown eyes.
Explanation:
In this example, B represents the allele for brown eyes which is dominant and b represents the allele for blue eyes which is recessive. The color of the eyes, brown and blue are the two phenotypes (physical appearance) obtained from the combination of these two alleles. Since B is the dominant allele (brown eyes), both the genotypes BB and Bb will produce brown eyes. The genotype (genetic code from the combination of alleles inherited from parents) of the child is Bb, so she has brown eyes. The offspring will get blue eyes, only if the genotype is bb (homozygous recessive).
Answer:
Cells – except for cancerous ones – cannot reproduce forever. When aging cells stop dividing, they become “senescent.” Scientists believe one factor that causes senescence is the length of a cell's telomeres, or protective caps on the end of chromosomes. ... As telomeres dwindle, cell division stops altogether.
