Answer: 1 the complete set of sequences that Xist interacts with in an organism
Explanation:
The epigenome is the collection of all the epigenetic marks in the DNA of a single cell, thus referring to the complete set of modifications that occur in the chromatins that each organism has.
Regulatory elements in cis are non-coding regions of DNA that are capable of regulating the transcription of nearby genes.
DNA methylation is a process whose objective is to add methyl groups to the DNA molecule in the cell, in this process a change in the activity of a segment of DNA can occur without this meaning changing the sequence.
The sequence of DNA methylation sites occurs within the genome of an organism
In 1952, Alfred Hershey and Martha Chase performed experiments showing that DNA is the genetic material
Answer:
The correct option are a) Meiosis 1 in mother c)Meiosis 1 in father d) Meiosis 2 in father
Explanation:
If a normal haploid sperm fertilizes an egg that has undergone non-disjunction in meiosis 1 than offsprings produced might be having Aaa genotype.
If a normal haploid sperm fertilized an egg that had undergone non-disjunction in meiosis 2 then the chances of the offsprings being formed would be AAa
, aaa
, Aa
, aa
, a. Hence, option B is not correct.
Answer:The ocean is constantly in motion, moving water from place to place via currents. The Gulf Stream brings warm water from the Gulf of Mexico all the way up to the Norwegian Sea. As the warm water comes in, colder, denser water sinks and begins moving south—eventually flowing along the bottom of the ocean all the way to Antarctica.
