Endocrine System Is a group of specialized organs and body tissues that produce‚ store‚ and secrete chemical substances known as hormones. As the body’s chemical messengers‚ hormones transfer information and instructions from one set of cells to another. Because of the hormones they produce‚ endocrine organs have a great deal of influence over the body. Among their many jobs are regulating the body’s growth and development‚ controlling the function of various tissues‚ supporting pregnancy

Balao‚ Mike Paul C. MT1311 Chromosomal aberrations are abnormalities in the structure or number of chromosomes and are often responsible for genetic disorders. For more than a century‚ scientists have been fascinated by the study of human chromosomes. It was not until 1956‚ however‚ that it was determined that the actual diploid number of chromosomes in a human cell was forty-six (22 pairs of autosomes and two sex chromosomes make up the human genome). In 1959 two discoveries opened a new era

Formal lab report: Abstarct: The Purpose of this experiment was to perform Agrobacterium-mediated transformation in Wild type Arabidopsis thaliana Columbia by using somatic plant transformation method. The whole process lasted for over a period of 11 weeks and we were successful in getting transformed plants. Agrobacterium tumefaciens strain containing pMP90 (Ti-helper) plasmid and pCAMBIA1391 (T-DNA) plasmid was used for this plant transformation. pCAMBIA1391 plasmid was constructed by cloning Brassica

4.1.1 State that eukaryote chromosomes are made of DNA and proteins.(1) State means to give a specific name‚ value or other brief answer without explanation or calculation. The chromosome is composed of two main molecules. a) DNA b) Proteins called histones. This image was taken shortly after DNA a replication but before the prophase. It is composed of two daughter chromatids joined at the centromere. The chromosome is super coiled by a factor around x16‚000. The DNA molecule is about 1
