caused by a deformity in their chromosomes‚ in other words‚ they have forty-seven instead of forty-six chromosomes (14). There are three different types of this disability‚ some more severe than others. The three types are trisomy twenty-one‚ translocation‚ and mosaicism. Trisomy twenty-one is caused by an error in the cell division. Translocation occurs when part of the cell breaks off. Mosaicism‚ the least common form‚ is where they contain an extra chromosome (NDSS). There are many different symptoms

Down syndrome- A condition that occurs when a person has three 21-chromosomes. Many people with down syndrome have problems with their heart‚ get lung infections easier‚ and are likely to eventually get leukemia and Alzheimer’s. duplication- This occurs when part of a chromosome is removed from one chromosome and

Chapter 12 Cyclins and cyclin-dependent kinases are regulatory proteins that assist in the cell cycle. Particular protein kinases give the go-ahead signals at G1 and G2 checkpoints. These protein kinases are present at a constant concentration in the cell but are inactive unless in the presence of cyclin‚ these are cyclin dependent kinases. The activity of a cdk rises and falls with the concentration of cyclin. Cyclin levels rise during the S and G2 phases then fall abruptly in the M phase

Mitosis Review 1. So why does cell division occur? Cell division occurs because an organisms such as plants‚ animals and such need to grow on a molecular level in order for them to continue thriving. For example‚ new cells are created with the intention of replacing old cells and tissues‚ with fresh and functioning ones... for most part. In humans and other organisms‚ organ cells‚ muscle cells‚ bone cells and such are constantly replace for growth and prolongation of proper function. Also‚ embryos

PREP has two members in mice and humans‚ known as PKNOX1/ PREP1 and PKNOX2/ PREP2. Sequence comparisons indicate that PREP1 and PREP2 define a novel sub-family of MEINOX proteins. PKNOX1 is composed of 435 amino acids and mapped on human chromosome 21 (21q22.3). In complexes with PBX (another TALE family member)‚ PREP1 regulates the transcription of HOX-dependent (Hoxb2) and HOX-independent (urokinase plasminogen activator‚ glucagon) target genes. PKNOX2 is composed of 460 amino acids and contains
