Which of the following is a correct statement? select one:
a. if you want to make a cdna library, it doesn't matter which tissue you isolate the mrna from.
b. if you want to make a genomic library, it doesn't matter which tissue you isolate the dna from.
c. if you want to make a cdna library, it doesn't matter which tissue you isolate the dna from.
d. if you want to make a genomic library, it doesn't matter which tissue you isolate the mrna from.

The correct answer is a if you want to make a cDNA library it does not matter which tissue you isolate the mRNA from.

Explanation:

cDNA is also called complementary DNA is generated from mRNA molecule by the process called reverse transcription with the help of reverse transcriptase enzyme.

    During the formation of cDNA library at first mRNA is being isolated from a cell but it does not matter from which cell the mRNA is isolated because cDNA library is not specific for any particular mRNA present in a cell.

   In a library there are various types of books.A library is not specific for a single type of book by the same way cDNA library is not specific for a single type of mRNA.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
