Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

In any one species, the amount of adenine closely approximates that of thymine.
In any one species, the amount of guanine closely approximates that of cytosine.
The amounts of A, T, G, and C in DNA varies from species to species.

(options A, B and D)

Explanation:

Organizing the data has to:

Source of DNA A T G C

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

An organism has three different versions of Gene Tyx – version a, b and c. Determine the inheritance pattern of this trait. Then

Rina8888 [55]

Explanation:

As we know that different versions of the gene are called as the alleles. Allele is the various sequence of DNA (deoxyribonucleic acid) or alleles are known to be different forms of the genes, which can be seen at the same locus on the homologous chromosomes. Let us know assume that gene Tyx has two alleles in it, which represents the two forms of expression having same character. i.e. Tallness and Dwarfness TT(tall), Tt(tall), tt(dwarf). In the given question, the version

(a) TT, where alleles exist in the homozygous dominant conditions,

(b) Tt, where alleles exist in the heterozygous dominant condition

(c) tt, where alleles exist in homozygous recessive condition. Therefore, it might follow autosomal dominant inheritance, or autosomal recessive inheritance or incomplete dominance etc.

The initial step in the synthesis of the hormone known as vitamin D demonstrates the interaction of multiple organ systems as in

Naddik [55]

Answer: Endocrine system

Explanation: The integumentary system is that is made up of the skin, hair, nails and the Endocrine glands. The following functions of the integumentary system are:

a. It protects skin from any form of damage which could be in form dehydration.

b. It protects the skin by secreting an hormone called melanin which protects the skin from ultra violet radiation.

c. The integumentary system helps in regulating and maintaining the body temperature

d. The skin which is part of the integumentary system secretes Vitamin D which is an essential in building of strong and healthy bones.
