A student has drawn an enlarged portion of a dna "ladder" model to show two of the nucleotides in greater detail (in the same or

ientation as they would occur in the ladder model). Which two nucleotides did the student draw?

The student either drew the base-pairing showing adenine and thymine or guanine pairing with cytosine.

Further Explanation:

The nucleic acid makes the DNA. The nucleic acid is made up of nucleotides. Each nucleotide is made up of a phosphate group, deoxyribose, and a nitrogenous base. Gene is defined as the linear sequence of the nucleotides that are mainly encoded for a protein having a particular function. The alleles are defined as the variant type of the gene. DNA is mainly made up of the nucleotides and also contains genetic information in the genes. DNA has mainly four different types of a nitrogenous base  

  • Adenine
  • Cytosine  
  • Thymine
  • Guanine

The nitrogenous bases are divided into two groups called the pyrimidines and the purines. The pyrimidines include the thymine and cytosine; the purines are adenine and guanine.The nitrogenous bases in the double helix are bound together according to the base-pairing rule—adenine pairs with thymine (A-T) and guanine pairs with cytosine (G-C). The student either drew the base-pairing showing adenine and thymine or guanine pairing with cytosine.

A DNA molecule consists of two stands of nucleotides that wind around each other like a twisted ladder with a phosphate and sugar backbone. The  nitrogenous bases are divided into two groups called the pyrimidines and the purines. The pyrimidines include the thymine and cytosine, the purines are adenine and guanine.  The nitrogenous bases in the double helix are bound together according to the base pairing rule. Adenine pairs with thymine (A-T) and guanine pairs with cytosine (G-C). The student either drew the base pairing showing adenine and thymine or guanine pairing with cytosine.

Contrast meiosis with mitosis, mentioning homologous chromosomes, chromatids, tetrads and crossing over.
Ratling [72]

Answer:

Explanation:

Mitosis takes place in somatic cells of the body while the meiosis takes place in the germ cells. The mitosis is the equational division while the meiosis is reductional division.  

The meiosis has 2 cell divisions i.e. meiosis I and meiosis II. The mitosis is a single division.

The pairing between the homologous chromosome/synapsis occurs in meiosis. It is not found in mitosis.  

During the pachytene stage of meiosis, crossing over takes place. The homologous chromosome exchanges its genetic materials in crossing over.

In mitotic cell division, the chromatids do not exchange their genetic material.

The chromosome numbers are always the same as the parent cell in the mitotic division. In meiosis, the number of the chromosome turns to half of their parent cells.

There are 4 haploid chromosomes/tetrads forms at the end of meiosis. In meiotic division 2 chromosomes form from the parent cells.

the zonation of flora and fauna along an altitudinal transect similar to that found along latitudinal transects is an expression
frutty [35]

The zonation of flora and fauna along an altitudinal transect similar to that found along latitudinal transects is an expression of the the life zone concept.

<h3>What is life zone concept?</h3>
  • C. Hart Merriam created the term "life zone" in 1889 to refer to regions with comparable plant and animal groups. Depending on height, location, and latitude, the climate and ecology of many places on the planet naturally divide into life zones.
  • Altitudinal zonation is the term for the generally substantial dependence on elevation: the average temperature of an area falls as the height increases.
  • The US has thirty-eight life zones, including one boreal, twelve cool temperate, twenty warm temperate, four subtropical, and one tropical (34% of the world's life zones and 85% of the temperate ones).
