The basic difference between active genes and inactive genes is that active genes are expressed whereas inactive genes are not expressed. This is due to the DNA methylation of the sequences. For DNA replication or copying it must be accessible to the enzymes and the enzymes can access euchromatin and cannot access heterochromatin. The euchromatin is loosely packed form of DNA while heterochromatin is tightly packed form of the DNA. Therefore, the heterochromatin contains the active form of inactive form of genes or the genes are said to be silenced. The DNA bound around the histone proteins are heterochromatins are inaccessible to the enzymes as the histone proteins are in methylated form. The methylation of the histone proteins keeps the genes inactive.

Predict the outcomes of a plant with 6 diploid chromosomes that fertilized a similar plant in which the egg failed to undergo me
Evgen [1.6K]

Answer:

The correct answer would be - triploid plant.

Explanation:

Triploidy is a condition which can be defined as the 3 set of chromosome in an organism, the extra set of chromosome may be come from the maternal organism or the paternal derived. Maternal derived triploidy known as the digynic while in in the case of the paternal derived called diandric.

In this case the sperm goes under the meiosis so the each gamete will have one chromosome of each set (I I I) while the egg failed to undergo meiosis so the gamete carry complete set of chromosome ( II II II ) after fertilization the outcome will be Digynic triploidy (III III III).

Thus, the correct answer would be - triploid plant.

Why do animal cells have many small vacuoles and plant cells have 1 or 2 large vacuoles?
valina [46]
The plant cells vacuole is larger compared to the animals cells' because the plants vacuoles takes up 90% of the cells volumes. Vacuole stores food for the organism. In this case since, plants manufacture their own food, it is necessary for it to have a large storage space or a large vacuole.
