Examples of I-band in the following topics:
-
- The I-band is spanned by the titin
molecule connecting the Z-line with a myosin filament.
- The region between two
neighboring, parallel I-bands is known as the A-band and contains the entire
length of single myosin myofilaments.
- At the level of the sliding
filament model, expansion and contraction only occurs within the I and H-bands.
- During contraction myosin ratchets along actin myofilaments compressing the I and H bands.
- During stretching this tension is release and the I and H bands expand.
-
- At the point, the molecules stopped sedimenting and formed a stable band.
- The molecules that form the lowest bands have the highest densities.
- The DNA harvested from cells grown for two generations in 14N formed two bands: one DNA band was at the intermediate position between 15N and 14N and the other corresponded to the band of exclusively 14N DNA.
- Dispersive replication would have resulted in exclusively a single band in each new generation, with the band slowly moving up closer to the height of the 14N DNA band.
- DNA grown in 15N (red band) is heavier than DNA grown in 14N (orange band) and sediments to a lower level in the cesium chloride density gradient in an ultracentrifuge.
-
- In a given species, chromosomes can be identified by their number, size, centromere position, and banding pattern.
- Giemsa staining results in approximately 400–800 bands (of tightly coiled DNA and condensed proteins) arranged along all of the 23 chromosome pairs.
- An experienced geneticist can identify each chromosome based on its characteristic banding pattern.
- In addition to the banding patterns, chromosomes are further identified on the basis of size and centromere location.
- Notice that homologous chromosomes are the same size, and have the same centromere positions and banding patterns.
-
- This layer multiplies into a band which then splits internally to form the coelom; this protostomic coelom is termed schizocoelom.
- Trochophore larvae are characterized by two bands of cilia around the body.
-
- Because the ddNTPs are fluorescently labeled, each band on the gel reflects the size of the DNA strand and the ddNTP that terminated the reaction.
- Reading the gel on the basis of the color of each band on the ladder produces the sequence of the template strand .
- The DNA is separated on the basis of size, and these bands, based on the size of the fragments, can be read.
-
- The clitellum is a reproductive structure that generates mucus that aids in sperm transfer and gives rise to a cocoon within which fertilization occurs; it appears as a fused band in the anterior third of the animal .
- It can be seen in this image as the enlarged band around the animal.
-
- They differ by the presence or absence of striations or bands, the number and location of nuclei, whether they are voluntarily or involuntarily controlled, and their location within the body.
- Smooth muscle tissue is also called non-striated as it lacks the banded appearance of skeletal and cardiac muscle .
-
- The DNA of every individual will give rise to a unique pattern of bands when cut with a particular set of restriction endonucleases; this is sometimes referred to as an individual's DNA "fingerprint."
- Certain regions of the chromosome that are subject to polymorphism will lead to the generation of the unique banding pattern.
-
- With this method, researchers capture animals and mark them with tags, bands, paint, body markings, or some other sign.
- With the mark and recapture method, researchers capture animals and mark them with tags, bands, paint, body markings or some other sign.
-
- During prophase I, chromosomes condense and become visible inside the nucleus.
- In anaphase I, the microtubules pull the attached chromosomes apart.
- In telophase I, the separated chromosomes arrive at opposite poles.
- Early in prophase I, homologous chromosomes come together to form a synapse.
- In this case, there are two possible arrangements at the equatorial plane in metaphase I.
