Chromatids are only called as chromatids when they are sister chromatids, meaning that when chromosome have two double stranded DNA attached together, each of the double stranded DNA is a sister chromatid, and while the whole thing (the two sister chromatids that are attached together) is called a chromosome.
So after the DNA has been replicated, the chromosome consist of 2 sister chromatids, attached to each other at their centromere.
Overall, sister chromatid is one of the two double stranded DNA in a replicated chromosome, and chromosome is the whole "X" shape that we see. For example, in humans, after the S phase of interphase in the cell cycle, we have 46 chromosomes, with 92 chromatids, since each chromosome is an "X" shape, by having two sister chromatids.
Hope this helps!
They are sandwiched between two layers of heads. Recall that the heads are hydrophilic therefore they will always be on the outside and the tails are hydrophobi therefore they willl always be away from water, there fore sandwiched. I'm a bio major, hope I helped :)
Answer:
In acupressure, pressure points are thought to be powerfully sensitive parts of the body. Some people believe that by applying pressure to our body’s pressure points, it can help relieve pain, establish balance, and improve health throughout the body.
Explanation:
Genotype refers to the complete genetic make-up and can also be referred to as the alleles an organism carries on a particular gene.
John's genotype with unattached being dominant is Aa.
- Using A to represent the alleles
- Since his mother has attached earlobes, her condition can only be inherited in the recessive condition (aa).
- So for John to have an unattached earlobe, his father has to be either AA or Aa.
- Therefore John's genotype would be Aa
