1.Nitrogen – Fixing Bacteria
Organisms that is responsible for nitrogen fixation belong to the group of prokaryotes. Their main function involves the conversion of stable nitrogen gas in the atmosphere to a biologically useful form. Nitrogenase is an enzyme complex that reduces dinitrogen to ammonia.
A huge amount of energy is consumed during the nitrogen fixation and the nitrogenase enzymes are irreversibly inactivated by oxygen.
2.DNA (deoxyribonucleic acid) is a double helix molecule made up of long chains of nucleotides. ... It can also be defined as the segment of DNA which codes for a particular molecule. DNA is present as chromatin fiber in non-diving cells. It is formed with the help of nucleosomes
3.Both mitochondria and plasmids have some of their own DNA for protein synthesis hence they are called as semi autonomous cell organelles. The difference between plastid and mitochondria is that plastid are found in plant cells and mitochondria are found in both plant and animal.
4. because quality matters more than the quantity simply increasing the grain production and not increasing the quality of the food will definitely lead to malnutrition and hunger
hope it helps you
these are some important questions so please make sure that you know it
all the best for your up coming exams keep rocking :) :) :)
chromosome. DNA is present in form of chromatin fibres
DNA (deoxyribonucleic acid) is a double helix molecule made up of long chains of nucleotides.
Nucleotides are joined with each other with the help of phospho-di-ester bond.
A nucleotide consists of a deoxyribose sugar, a phosphate group, and a nitrogenous base (adenine, cytosine, tyrosine, or guanine). Sugar and phosphate group make the backbone of the DNA whereas as nitrogenous bases are involved in the formation of base-pairs.
A gene is a functional unit of heredity. It can also be defined as the segment of DNA which codes for a particular molecule.
DNA is present as chromatin fiber in non-diving cells. It is formed with the help of nucleosomes.
DNA contains genes and histone proteins
functional segment of DNA is Gene. at the time when cell is not dividing we find chromatin in DNA
DNA CONTAINS NITROGENOUS BASES.
DNA contains the geans which decided that how should you look. It present in linear form.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base.
Genes are the functional segments of DNA. The are the smallest units of DNA which are capable of performing independent function.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code
