Answer:
cellular respiration
Explanation:
its called cellular respiration
Answer and Explanation:
The steps for construction of the expression plasma
- STEP 1 : Introducing Notl and Hindlll confinement sites at the ends of the gene of interest by means of PCR
- STEP 2 :Digest the plasmid and DNA encoding gene with the Notl and Hindol confinement endonucleuses.
- STEP 3 : Ligate the cut plasmid and DNA fragment
- STEP 4 : Change the plasmid into E.coli for expression
- STEP 5 : Clean the protein by utilizing a column of immobilized
Answer:
Most protists have mitochondria and chloroplasts. This is statement is true.
Explanation:
Protists are the organisms that are eukaryotes i. e. have true nucleus and made of single cell. Most of the protists contain chloroplast. These protists are green in color due to the presence of chlorophyll that's why they make their own food like plants. Some protists also contains mitochondria which generates energy from the food they eat.
Answer:
Mitochondria
Explanation:
Mitochondria can be described as the organelle which is the powerhouse of the cell. These organelles also function to maintain homeostasis of the body. The mitochondria of a cell use up oxygen and nutrients from the body and convert them into energy and heat. The heat is used to maintain the temperature of the organs and body. Hence, the heat-generating organ would have the organelles, mitochondria, in abundance in its cells.
Attachment of acetyl groups to histone promotes transcription.
This mechanism is known as histone acetylation and it is a part of gene expression. The lysine residues inside the N-terminal tail from the histone core of the nucleosome are the substrate for enzymes-histone acetyltransferase which transfer an acetyl functional group from another molecule. Acetylation removes the positive charge on the histones and thus decrease the interaction negatively charged phosphate groups of DNA. As a result, chromatin becomes more relaxed structure and transcription is promoted.
