Answer:
H1
Explanation:
Histones H2A, H2B, H3 and H4 are known as the core histones which means that there are building nuclesome. H1 is known as the linker histone which binds to the "linker DNA" region between nucleosomes, helping stabilize the chromatin fiber. The linker histone H1 binds the nucleosome at the entry and exit sites of the DNA, thus locking the DNA into place and allowing the formation of higher order structure.
CO2 is returned to the atmosphere by all methods except photosynthesis.
Through photosynthesis, a plant actually takes CO2 from the atmosphere and produces oxygen in return.
Transcription starts at the template strand of DNA where mRNA attaches and is constructed from 5’ to 3’ direction. The nucleotides of the DNA strand is attached to either A, U, G, C ribosomal nucleotides. mRNA Dissembles when it reaches a terminating codon and then it attaches to ribosomal RNA where tRNA carries the amino and mRNA caries the code to construct proteins with the ribosome.
