Answer: -inherited genes and environment
Inherited genes are the genes which an organism acquires from his parent. These genes are responsible for constructing genetic make up of the organisms. These genes are expressed in order to develop observable characteristics in organism also, called as phenotypic characteristics for example how an organism looks, behaves and reacts to external stimuli are all phenotypic characteristics. Environmental factors induces genetic and phenotypic changes in an individual to add up more traits which are beneficial to survive in changing environmental conditions for example maintenance of homeostasis in cold weather conditions, genetic traits will develop in order to compensate for loss of heat.
Answer:
DNA replication is initiated by the help of these enzymes.
Explanation:
Helicase enzyme helps is unwinding the two complementary strand of DNA by hydrolysing the hydrogen bonds present between the nitrogenous bases of the two opposite strands.
Topoisomerase enzyme help in expansion of the Replication bubble by releasing the super coiling or tension occured while unwinding by helicase. It breaks the phosphate bonds in one of the two strands ahead of replication bubble or fork to release super coiling or overwinding.
Single-strand binding proteins gets bind to the separated strands to stabilize the structure of Replication bubble or to keep the both strand separated from each other.
Answer:
The macromolecule is nucleic acids (more importantly the nucleotides)
Explanation:
Nucleotides belong to the DNA/ nucleic acid part of macromolecules.
