What is a multicelled organism?
The smallest multi-celled organism in the world is C. elegans. It has 959 somatic cells and is a few millimeters in length. It has an estimated 17,800 genes which is about half the amount of genes in a human.
A small impermeable membrane is placed between the anchor cell and the other vulva precursor cells in a larva of C elegans What would you expect the result to be?
The outer part of the vulva would develop, but the inner part would not.
What are the two main functions of nuclear envelope?
The nuclear envelope is a double membrane structure surrounding the nucleus. Its function is to provide compartmentalization to regulate the movement of materials in and out of the cell, and to provide structural support of the nucleus.
What protein do all organisms have in common?
The best example is probably histones. There is lots of variety within proteins though. if you look at a specific protein in 2 different species, even if the two proteins do the same job, they may be mostly different.Some proteins will be found in most mammals, with high 'sequence identity' like those related to muscles (e.g. titin, actin and mysosin) or cell cytoskeleton (e.g. tubulin) but histones tend to be well conserved among all eukaryotes (all things with nuclei) from amoebas to blue whales or c. elegans to humans, with only one or two amino acids different.
When DNA is copied to form chromosomes that have 2 sister chromatids this is called DNA .?
Each chromosome has two arms, labeled p (the shorter of the two) and q (the longer). The p arm is named for "petite" meaning 'small'; the q arm is named q simply because it follows p in the alphabet. (According to the NCBI, "q" refers to the French word "queue".) They can be Metacentric A chromosome is metacentric if its two arms are roughly equal in length. In some cases, a metacentric chromosome is formed by balanced Robertsonian translocation: the fusion of two acrocentric chromosomes to form one metacentric chromosome. Submetacentric If arms' lengths are unequal, the chromosome is said to be submetacentric Acrocentric If the p (short) arm is so short that is hard to observe, but still present, then the chromosome is acrocentric (The "acro-" in acrocentric refers to the Greek word for "peak."). In an acrocentric chromosome the p arm contains genetic material including repeated sequences such as nucleolar organizing regions, and can be translocated without significant harm, as in a balanced Robertsonian translocation. The domestic horse genome includes one metacentric chromosome that is homologous to two acrocentric chromosomes in the conspecific but undomesticated Przewalski's horse. This may reflect either fixation of a balanced Robertsonian translocation in domestic horses or, conversely, fixation of the fission of one metacentric chromosome into two acrocentric chromosomes in Przewalski's horses. A similar situation exists between the human and great ape genomes; in this case, because more species are extant, it is apparent that the evolutionary sequence is a reduction of two acrocentric chromosomes in the great apes to one metacentric chromosome in humans Telocentric A telocentric chromosome's centromere is located at the terminal end of the chromosome. Telomeres may extend from both ends of the chromosome. For example, all mouse chromosomes are telocentric Holocentric With holocentric chromosomes, the entire length of the chromosome acts as the centromere. Examples of this type of centromere can be found scattered throughout the plant and animal kingdoms with the most well known example being in the worm, Caenorhabditis elegans.
