Mechanisms for chromosome movement Animation

By: HWC, Views: 1951

At mitotic metaphase, the fully-formed spindle is composed of many microtubules that extend from the poles. Some of these, the kinetochore microtubules, are attached to the kinetochores of each chromosome. Kinetochores are located at the centromeres. At anaphase, sister chromatids separate and...

Chromosome structural organization/ Mechanisms for chromosome movement Animation

By: HWC, Views: 1037

How the chromosome is organized. At metaphase, the chromosomes are duplicated and are at their most condensed. In each chromosome, two identical sister chromatids are held together at a constricted region called the centromere. When a chromosome is condensed, interactions among chromosomal ...

At metaphase, the chromosomes are duplicated and are at their most condensed. In each chromosome. two identical sister chromatids are held together at a constricted region called the centromere. When a chromosome is condensed, interactions among chromosomal proteins keep loops of DNA tightly ...

Metaphase I Animation

This is a cell during metaphase I. For each pair of chromosomes, any gamete produced by this cell could contain either the maternal chromosome or the paternal chromosome. How many different combinations of maternal and paternal chromosomes are possible in the gametes produced by a cell with th...

X chromosome inactivation in calico cats

By: HWC, Views: 1889

X chromosome inactivation causes a mosaic tissue effect in calico cats. what makes this female calico cat "calico." Like all mammals, this cat began her life as a single cell. That cell had two X chromosomes, one from each parent. One of the chromosomes carried a dominant allele for the ...

Wrist Circumduction Animation

By: Administrator, Views: 1100

Circumduction is sometimes described as simply a "circular movement" because circumduction movements of (e.g. the arm and hand) result in the outer edge of the limb (e.g. the fingertips) tracing circles in space. Another way to express this is to say that circumduction is the movement of the dist...

Types of body movement that occur at the diarthrotic joints: - Abduction - Adduction - Circumduction - Dorsiflexion

Forearm Movement Animation

By: Administrator, Views: 257

Muscles of both the upper arm and forearm control movement of the forearm. The biceps brachii flex the forearm and work with the supinator of the forearm to rotate it so the palm faces upward. The pronator teres and quadratus control pronation, or rotation of the forearm so that the palm faces do...
