When a tissue's metabolic rate increases, so does its carbon dioxide waste production. When released into the bloodstream, carbon dioxide forms bicarbonate and protons through the following reaction: ... These waste products lower the pH of the blood, which increases oxygen delivery to the active muscles.
Crossover occurs when two chromosomes, normally two homologous instances of the same chromosome, break and then reconnect but to the different end piece. If they break at the same place or locus in the sequence of base pairs, the result is an exchange of genes, called genetic recombination.
Answer:
The correct answer is 1 RNA Polymerase
Explanation:
RNA polymerase helps in the formation of RNA from DNA by the process known as transcription.There are 3 types of RNA Polymerase in Eukaryotic cell they are given below
1 RNA Polymerase 1 this enzyme helps in the synthesis of ribosomal RNA or rRNA.
2 RNA Polymerase 2 this enzyme helps in the formation of messenger RNA or mRNA .
3 RNA Polymerase 3 this enzyme helps in the synthesis of transfer RNA or tRNA.
