The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
Centromeres split during cell division in the mitotic phase called anaphase. As the sister chromatids are pulled apart towards opposite poles of the cell, the centromeres divide, forming individual chromatids that will become separate chromosomes in the daughter cells.
The sister chromatids (arms) are held together by centromeres. Centromeres are the site of attachment for the spindle fibers.
The structure that joins chromosome arms together is called the centromere. The centromere is essential for proper chromosome segregation during cell division and is the point where spindle fibers attach to the chromosome to facilitate this process.
The Achilles tendon structure joins the gastrocnemius to the calcaneus.
The DNA double helix wraps around a protein scaffold, which condenses, and joins with another condensed protein scaffold, which are more commonly known as the sister chromatids. These chromatids are also called a DNA chromosome. However, one strand of DNA has all the genes on it (AKA the nitrogenous bases A, T, C, and G; A matches with T, C matches with G - base pairing rules. These bases are kept together by weak hydrogen bonds.)You're welcome, kid.
When eggs and sperm are made, the DNA splits off in halves. Then when a sperm joins an egg, they recombine to form a new piece of DNA which is two perfect halves. Sometimes there is more or less info, this leads to defects which will prevent breeding, since people with the defect don't breed, the defect doesn't spread rapidly.
The structure that attaches bone to muscle is called a tendon.
The centrosome is a place inside the cell where microtubles are formed. inside the cell centrosome there are centrioles wich are made up of a ring of nine microtubules. these centrioles are only found inside animal cells. plant centrosomes function very similar to the animal centrosomes except for the fact that they do not have centrioles. They also play an important role in mitosis.
The structure that joins the skeletal muscle to the bone is called a tendon. Tendons are tough, fibrous cords that connect muscle to bone and help facilitate movement.
The chromosome number only doubles when two haploid gametes form to produce a diploid zygote. Example: In humans, sperm cells and eggs have 23 chromosomes, the haploid number. Once they fuse, the number doubles to 46 chromosomes. You may be confusing this with chromosome replication. In chromosome replication, the number of chromosomes does not double, but the number of strands double. (A single stranded chromosome turns into a double stranded chromosome.) However, it is still considered a single chromosome, but with identical sister chromatids. This replication occurs during the S-phase of the cell cycle, before mitosis or meiosis.
