If the green nitrogen base in the dna model represents adenine, the blue nitrogen base could represent
a) adenine
b) guanine
eliminate
c) thymine
d) uracil

The correct answer is-

B) guanine.

DNA ( deoxyribonucleic acid) is considered as the genetic material of living organisms. It is made up of small units called nucleotides. A nucleotide is hat is composed of -

1)nitrogenous base, which can be Adenine, Thymine, Guanine, Cytosine

2) Phosphate group, 3) Deoxyribose sugar.

In a DNA molecule, Adenine pairs with Thymine, and Guanine pairs with Cytosine as per the Watson and Crick base pairing.

If the green nitrogen base in the DNA model represents adenine, this indicates that thymine will also be green ( as it pairs with adenine).

Thus, the blue nitrogenous base will be represented by Guanine.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
