Which atom is responsible for joining nucleotides to build a new strand of DNA

Biology
1 answer:
joja [24]2 years ago

<span>Nucleotides are joined together similarly to other biological molecules, by a condensation reaction that releases a small, stable molecule. Unlike proteins, carbohydrates, and lipids, however, the molecule that is released is not water but pyrophosphate (two phosphate groups bound together). When pyrophosphate is cleaved by the addition of water, a great deal of free energy is released, ensuring that the reverse process (hydrolysis of the phosphodiester bond to give free nucleotides) is very unlikely to occur.</span>

Determine whether each example represents continental drift or sea floor spreading.
laila [671]

Answer:

Sea floor spreading-> <u><em>Oceanic ridge and Magma pushing two plates apart</em></u>

Continental drift-> <u><em>Concept of pangaea and Oceanic plates sliding under continental crust</em></u>

Explanation:

Due to the divergent plate movement, the magma come out to the surface, forming the mid oceanic ridge and this separation of plates on the sea floor is known as the sea floor spreading. The magma here pushes the two plates to move apart because of the convection current that generates in the mantle. One example of mid oceanic ridge is the Mid-Atlantic Ridge.

  Continental drift refers to the slow and gradual movement of the lithospheric plates over the viscous asthenosphere layer. This motion of continents takes place because of the plate tectonic movement. Due to this plate motion, the denser plate gets subducts beneath the less denser plates. For example, the oceanic crust when collides with a continental crust, it gets subducted because of its higher density. The great supercontinent "pangaea" also formed and separated due to this plate motion.

Critical protein-protein interactions within the CARMA1-BCL10-MALT1 complex: Take-home points for the cell biologist
dolphi86 [110]

Protein-protein interactions within the CARMA1-BCL10-MALT1 complex:

  • The T-cell receptor and B-cell receptor-dependent NF-B induction and lymphocyte activation are mediated by the CBM complex, which is made up of the proteins CARMA1, BCL10, and MALT1.
  • Each of the proto-oncoproteins CARMA1, BCL10, and MALT1 is a somatic gain-of-function mutation or chromosomal translocation, and dysregulation of CBM signaling is a characteristic of numerous lymphoid malignancies, including Activated B-cell Diffuse Large B-cell Lymphoma.
  • Moreover, a number of immunological dysregulation diseases have been linked to both gain- and loss-of-function germline mutations in CBM complex proteins.
  • Over the past ten years, careful examination of the interactions of CBM components has yielded a wealth of detailed structural knowledge.
  • Here, we discuss important discoveries about the molecular nature of these protein-protein interactions that have helped the research develop a detailed understanding of how these proteins come together to form high-order filamentous CBM complexes.
  • Approaches to therapeutic suppression of the CBM complex have thus far centered on obstructing MALT1 protease activity in order to treat lymphoid malignancy and/or autoimmunity.
  • The structural effects of MALT1 protease inhibitors on significant protein-protein interactions are also reviewed in detail.

What do a dinosaur and a tree have in common?
KengaRu [80]

Answer:

The correct answer will be option- A

Explanation:

Both dinosaur and the trees are the living organisms which share many characteristics of the living organisms.

Among the given choices, the most common things between these two different species of the living organism are that they are made of the same constituents which makes the lowest organization of life on earth that is the cell.

Since the cells of both tress and the dinosaur are made up of the same matter or the constituent elements arranged in similar fashion therefore, the selected option is the correct answer.

Which explanation below best describes why meiosis produces haploid cells?
Agata [3.3K]

Answer:

Egg and sperm cells have to have half the number of chromosomes as in  body cells so when they combine to form a zygote, the zygote is diploid  and has the correct number of chromosomes. This explanation describes why meiosis produces haploid cells.

Explanation:

Meiosis is a type of cell division in which four haploid cells are produced from a diploid parent cell having two copies of each chromosome, where the number of chromosomes in the parent cell is reduced to half by undergoing DNA replication and nuclear division. Diploid cell contains two copies of each chromosome, one inherited from mother and the other from father while haploid cell contains only one copy of each chromosome. Examples of diploid cells (somatic cells) are skin, blood, muscle cells etc. Eggs or ovum (female gametes) and sperm (male gametes) are haploid reproductive cells. If the total number of chromosomes in a diploid cell is represented as '2n', then the number of chromosomes in a haploid cell is 'n'.  During the fertilization process in an organism, the correct number of chromosomes is restored when the haploid male and female gamete combined to form a single diploid zygote, which is the first developmental stage of an organism.
