Which sentence is correct? All cells have the same genes, but different genes are active in different cells. Lungs look differen
mihalych1998 [28]

<u>Answer:</u>

All cells have same genes, but different genes are active in different cells

<u>Explanation:</u>

       Most living organisms are made up of different kinds of cells specialize in performing various functions like nerve cells perform different functions than blood cells. But all the cells are composed of same set of genetic information.

Since biochemical function is found out mainly by some specific enzymes, different sets of genes must be turned on and off in the various cell types to perform different functions. This is how cells differentiate for different functional capabilities.

Boris Magasanik collected data on the proportion of each base in RNA from different species. To compare the relative amount of e
just olya [345]

Answer:

The nucleic acid is a macromolecule present in living systems in the form of either DNA or RNA, whose molecule consists of many nucleotides which are linked with each other to form long chains. The presence of DNA or RNA in an individual promotes continuity of life. The variability and complexity of nucleic acid are dependent on its constituent molecules as, sugar, a phosphate group, and a nitrogenous base. However, two monocyclic nitrogenous bases were classified purines (adenine:A, guanine:G) and pyrimidines (thymine:T, cytosine:C, and uracil:U).

In addition, RNA is a single-stranded structure which differs from DNA in two aspects, the sugar content of RNA is ribose, and pyrimidine base uracil replaces the thymine base of DNA. A ratio between two strands of DNA can be calculated by using Chargrff's rule which states that "DNA from any cell of all organisms possess a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases'.

The purine to pyrimidine ratio in RNA with different bases is given below in the following table:

Presence of single strand in RNA does not follow chargaff's rule and alters the purine: pyrimidine ratio. The above ratio of each base in the given information is not equal, due to which the ratio of purines to pyrimidines is different. The ratio of DNA and RNA is not equal because DNA has its complementary DNA strand. However, bases in RNA might vary due to its single-strandedness property, but its ratio is dependent on the species.

Therefore, it can be concluded that the ratio of purines to pyrimidines is dependent on the species due to its genetic makeup. Hence, option (c) is correct.

tatuchka [14]

Answer:

cDNA library.

Explanation:

Genomic library may be defined as the collection of all the genomic DNA of an individual. The genomic library is constructed by the digestion of digestion of DNA fragments and there further transfer in the vectors.

cDNA library is prepared in case of eukaryotes because the complementary DNA is produced from the RNA. The eukaryotes DNA is interrupted with exons. In case of spider, the cDNA linrary is prepared because its DNA is interrupted with exons.

Thus, the answer is cDNA library.
