Answer:

D) with the phosphodiester backbone and with bases via the minor groove

Explanation:

The double helix is ​​a fairly rigid and viscous molecule of immense length and a small diameter. In this molecule a major groove and a minor groove can be observed.

The major groove is deep and wide, the minor groove is shallow and narrow.

DNA-protein interactions are essential processes in cell life (activation or repression of transcription, DNA replication and repair).

Proteins bind to the inner part of the DNA grooves, through specific junctions: hydrogen bonds, and non-specific junctions: van der Waals interactions, and other general electrostatic interactions.

The proteins recognize donors and acceptors of hydrogen bonds, methyl groups (hydrophobic), the latter exclusive of the major groove; There are four possible patterns of recognition in the major groove, and only two in the minor groove (see figures).

Some proteins bind to DNA through the major groove, some others through the minor groove, and some need to bind to both, but the nucleosome form hydrogen bonds via the minor groove with the phophodiester backbone.

Which type of cell division only occurs in organisms whose cells contain chromosomes?
Lelechka [254]
<span>Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. While meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. </span>

Describe the positive and negative interactions that affect populations in the tundra ecosystem
SCORPION-xisa [38]
Living organisms in any biome interact through a variety of relationships. Organisms compete for food, water, and other resources. Predators hunt their prey. Some organisms coexist in mutually beneficial relationships (symbiosis), while others harm organisms for their own benefit (parasitism). Still others benefit from a relationship that neither helps nor harms the other organism (commensalism).

Animals found in the Arctic tundra include herbivorous mammals (lemmings, voles, caribou, arctic hares, and squirrels), carnivorous mammals (arctic foxes, wolves, and polar bears), fish (cod, flatfish, salmon, and trout), insects (mosquitoes, flies, moths, grasshoppers, and blackflies), and birds (ravens, snow buntings, falcons, loons, sandpipers, terns, and gulls). Reptiles and amphibians are absent because of the extremely cold temperatures. While many of the mammals have adaptations that enable them to survive the long cold winters and to breed and raise young quickly during the short summers, most birds and some mammals migrate south during the winter

Which group of macromolecules includes triglycerides waxes and cholesterol?
Mkey [24]

Answer:

Carbohydrates, Nucleic acids, Proteins, and Lipids

A carbohydrate is a biological molecule consisting of carbon, hydrogen and oxygen atoms, usually with a hydrogen–oxygen atom ratio of 2:1.

Nucleic acids are bio-polymers, or large bio-molecules, essential for all known forms of life.

Proteins are large bio-molecules, or macro-molecules, consisting of one or more long chains of amino acid residues.

In biology, lipids comprise a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, and others.
