A researcher is comparing the sequences of genes encoding cell wall proteins in archaeons with those coding cell wall proteins i

n bacteria. How similar do you expect these sequences will be?
Biology

SSSSS [86.1K]2 years ago
8 0

Answer:

These sequence with not be similar because, the archaeons cell wall lack peptidoglycan.

Explanation:

The peptidoglycan is made up of peptide chain and polysaccharide. They are mostly found on bacterial cell. It gives structure to the organism and provide strength to the outer structure of the organism as well.

The cell wall of most archae are composed of S-layer protein. The cell wall also composed of other sugar proteins like pseudomurein, heteropolysaccharide and methanochondriotin.

In this case,  the sequences will be different , simply because of the difference in the composition of their cell walls.

The nutritional energy content (in Calories) present in 86g of broccoli with 2.6g of protein, 6g of carbohydrates, and 0.3g of f
Nimfa-mama [501]

Answer:

40 Cal

Explanation:

Data provided in the question:

Protein present in the broccoli = 2.6 g

Carbohydrates present in the broccoli = 6 g

Fat present in the broccoli = 0.3 g

Now,

We know,

Energy provided by protein and carbohydrates = 4 Cal / g

and,

Energy provided by Fats = 9 Cal / g

Therefore,

Total nutritional energy content = ∑(Amount × Energy provided)

= ( 2.6  × 4 ) + (6 × 4) + (0.3 × 9)

= 10.4 + 24 + 2.7

= 37.1 Cal    

rounding off the answer to nearest 5 ≈ 40 Cal

Which of the following is an important exception to the central dogma of molecular biology? a) Proteins are responsible for most
iogann1982 [59]

Answer:

b: many genes code for RNAs that function directly in the cell

Explanation:

<em>The central dogma</em> theory describes the basic framework for gene expression in living organisms. Genetic information from DNA is encoded or transcribed as RNA which then becomes translated as proteins.

The processes that take place for gene to be successfully expressed are;

  • Replication
  • Transcription
  • Translation

<em>Replication</em> is a process whereby DNA makes a copy of itself to be distributed in daughter cells during cell division.

<em>Transcription</em> is the process whereby genetic information in DNA is encoded as RNAs. The RNAs are short-lived as they are quickly utilized in protein synthesis or <em>translation </em>process.

Hence, the RNAs do not function directly in the cells but mere intermediaries in the synthesis of proteins.

<em>The correct option is b.</em>

If cyanide stops the production of atp what transport would cease
boyakko [2]
ATP is produced via 3 main ways. This being Glycolysis, Krebs Cycle and ETC or Electron Transport Chain. However Cynanide binds to something called the cytochrome C oxidase, which is part of the ETC, which means the ETC no longer produces the ATP required for the cell. Therefor your body can't produce the energy u need and you die.
