Answer:

1. DNA

2. RNA

3. Nucleus

4. Nuclear membrane

5. Nuclear pore

6. Nucleolus

7. Chromatin

Explanation:

DNA is present in nearly all living organisms. It has the capacity to replicate itself and also the capacity to be transcribed into RNA. The latter contains the genetic codes that are usually translated during protein synthesis.

The nucleus is the most prominent, membrane-bound (nuclear membrane) organelle in the eukaryotic cell. The nuclear membrane has a special pore, the nuclear pore, through which molecules can be transported between the nucleus and the cytoplasm.

Within the nucleus is the nucleolus, a spherical structure whose primary function is to make ribosomal subunits. The genetic materials in the nucleus are in the form of chromatin, a decondensed protein-DNA complex.

How does the density of liquid water compare with the<br> density of ice?
Orlov [11]

Answer:

The normal pattern for most compounds is that as the temperature of the liquid increases, the density decreases as the molecules spread out from each other. ... The ice structure takes up more volume than the liquid water molecules, hence ice is less dense than liquid water.

Which statements correctly describe mutations in gametes and mutations in somatic cells?
ASHA 777 [7]

A mutation is a rare, accidental or induced modification of genetic information (DNA or RNA sequence) in the genome.


The consequences of a mutation vary according to the part of the genome affected. A mutation is said to be hereditary if the mutated genetic sequence is passed on to the next generation.

In multicellular animals, germline mutations can be transmitted to offspring, whereas somatic mutations do.


Somatic mutations do not affect cells intended for reproduction, so they are never hereditary:

* Post-zygotic mutations are the mutations that appear in the egg after fertilization. They are rarer and are expressed as mosaic in the individual concerned (the mutation will be present only in the daughter cells originating from the mutated embryonic cell).

* Mutations can appear throughout life on the DNA of any cell; they are then transmitted to the line of the daughter cells. These can, in some cases, become tumor cells and then form cancer.
