Describe the roles of DNA and genes in inheritance and genetic variation.

Biology
1 answer:
Sergeu [11.5K]3 years ago

Answer:

Each gene occupies a specific position on a chromosome. Because genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body, it follows that genes are responsible for all the characteristics you inherit.

miv72 [106K]

Answer:

This question lacks proper arrangements but one can understand and chip in the appropriate terms. The terms missing there in order, which answers the question are:

Nucleus

Transcription

RNA polymerase

mRNA

Ribosome

Explanation:

The cellular process being described in this question is GENE EXPRESSION, which is the expression of the information contained in the genetic material in order to produce useful gene products (proteins). The genetic material (DNA) is stored in the nucleus of eukaryotic cells. The first process of this gene expression called TRANSCRIPTION involves the copying of the information contained in the DNA into an RNA molecule.

Transcription is carried out by an enzyme called RNA polymerase, which synthesizes a complementary strand of mRNA from a DNA template. mRNA ia called messenger RNA and it acts as a conveyer/carrier of this information present on its nucleotides out of the nucleus into the cytoplasm, specifically the site of protein synthesis called RIBOSOME.

The RIBOSOME is a cellular organnelle where the other process of gene expression called TRANSLATION will occur.

tino4ka555 [31]
The statement above is TRUE.
The osteon is the fundamental functional unit of a compact bone. Osteons are roughly cylindrical in shape and they are typically several millimetre long and about 0.2mm in diameter. The osteon resembles the growth ring of a tree trunk.
The cylindrical structure of osteon is made up of four different parts which are a central tube, a lamellae, a lacunae and canaliculi.
