Glycolysis occurs in the cytosol, but the Krebs cycle and electron transport chain occur inside the mitochondria. Electron carriers such as NADH produced during glycolysis and the Krebs cycle pass their electrons to the electron transport chain, which results in synthesis of a lot of ATP.

What conclusion about the bacteria domain could be made from the phylogenetic tree below?
Elden [556K]

Answer: The correct answer is -

D. Eukarya has similar evolutionary traits to archaea.

A phylogenetic tree (also known as evolutionary tree) is a diagrammatic representation (in the form of branch diagram) showing the evolutionary relationships among various organisms. It is constructed on the basis of similarities or differences in the genetic or physical characteristics of various species.

In the given phylogenetic tree, archaea domain shows more similarities to the domain eukarya as it has descended after the domain bacteria.

Thus, option D) is the right answer.

What holds the monomers of a single strand of nucleic acid together in a chain?
Tpy6a [65]

Answer:

Nucleic acids are of two types DNA and RNA which are made up of monomeric units called nucleotides.

One monomer is one nucleotide which further consists of three parts:

1: Nitrogenous base

2: Sugar (a ribose sugar in RNA and a deoxyribose sugar in DNA)

3: Phosphate group

Explanation:

If we talk about single strand of nucleic acid DNA or RNA, there is a phosphodiester linkage that holds monomers together in a strand of nucleic acids. This phospho di ester linkage is formed when a condensation reaction occurs between a hydroxyl group of two sugars and a phosphate group.

You can see a better representation in attached figure.

Hope it help!
