4 0

Answer:

True

Explanation:

Each replicated chromosome pairs with its corresponding homologous chromosome forming a tetrad. During tetrad formation, alleles can be exchanged between chromatids, a process called crossing-over.

" each molecule of hemoglobin, when fully saturated, carries _______ molecule(s) of oxygen."
Aleonysh [2.5K]
<span>4 molecules of oxygen. Haemoglobin is a protein found in the red blood cells, which carries oxygen to the cells to perform cellular respiration. Each red blood cell carries around 250 million haemoglobin. So the entire capacity of an RBC is around 1 billion oxygen molecules.</span>

In the 1950s, when Watson and Crick were working on their model of DNA, which concepts were well accepted by the scientific comm
julia-pushkina [17]

Answer:

Option (1), (2) and (3).

Explanation:

DNA is the genetic material of all the living organisms present on earth. The DNA contains the nitrogenous bases, pentose sugar and the phosphate group. DNA strands runs in the opposite direction and shows polarity.  

Watson and Crick explain the structure of DNA based on the X ray diffraction produced by Rosalind. According to the structure, chromosomes are present in the nucleus and contains the DNA and wrapped around the proteins. The genes is considered as the functional segment of DNA.

Thus, the correct answer is option (1), (2) and (3).

How are binary fission and mitosis similar?
daser333 [38]

Answer:

Both binary fission and mitosis produce genetically identical daughter cells.

Explanation:

The process in which new cells are made in order to grow, replenish (repair), and reproduce is called cell division . The three main types of cell division are binary fission, mitosis, and meiosis. In prokaryotes like bacteria  cell division take place through binary fission, while eukaryotes (e.g., plant and animal cells) uses two types of cell division - mitosis (the process of making new body cells like blood, muscle etc ) and meiosis (reproductive cell division that creates egg and sperm cells).

Binary fission is a simple and rapid process in which a single parent cell divides to form two genetically identical daughter cells. The main function of binary fission is reproduction.

In mitosis, a cell is replicated into exact copies of itself and duplicates all of its contents including the chromosomes and splits to form two identical daughter cells. It is a complex process in which cells pass through different phases called cell cycle during cell division.

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.

Both binary fission and mitosis are types of asexual reproduction in which the DNA is copied and the cytoplasm is divided (cytokinesis) to form two genetically identical daughter cells, which contain an exact copy of the parent cell's DNA.
