DNA is found in the nucleus of eukaryotic cells and the ribosomes, the location where proteins are made, are found out in the cy
Reika [66]

Answer:

See the answer below

Explanation:

<em>The DNA of eukaryotic organisms being present in the nucleus while the protein-synthesizing organelle, the ribosome being present in the cytoplasm poses a spatial problem. It means that transcribed DNAs (messenger RNA) in the nucleus would have to somehow be transported to the ribosome in order for the cell to successfully synthesize proteins.</em>

The problem of transporting the messenger RNA is solved by two features of the cell:

  • The presence of pores in the nuclear envelop
  • The presence of transport proteins in the nucleus

<u>The mRNA binds to the transport proteins to form mRNA-protein complexes and is transported through the nuclear pores, often with the assistance of ATP. </u>

Explain nitrogen fixation
AnnZ [28]
Nitrogen fixation is a process in which nitrogen (N2) in the Earth's atmosphere is converted into ammonia (NH3). Atmospheric nitrogen or molecular dinitrogen (N2) is relatively inert: it does not easily react with other chemicals to form new compounds.

Which two codons in the mRNA represent the amino acid phenylalanine
Trava [24]

Answer:

UUU and UUC

Explanation:

Information that encodes certain functional products called PROTEIN are present in the DNA molecule. However, the information needs to be expressed via the processes of transcription and translation. Transcription is the synthesis of a mRNA using a DNA template.

The mRNA then undergoes translation, where it is read in a group of three nucleotides called CODON. Each CODON specifies a particular amino acid. Due to the degenerate nature of the genetic code, more than one codon can specify one amino acid.

Hence, in the case of phenylalanine amino acid, codons UUU and UUC both specify it. This means that whenever UUU and UUC are read during translation, a phenylalanine is added to the peptide chain.

How does capillary action help sustain life on earth?
Yakvenalex [24]
Answer: A - Uptake of food and water by plants

The xylem vessels in the roots of the plants use the mechanism of capillary action and work against gravity to pull water molecules and nutrients from the soil and carry them upwards to the leaves of the plant to provide nourishment to the plant.

Leni [432]
If a person is "sterile", this means that they cannot reproduce. The word "sterilized" is essentially stating that there is no productive activity in order to be able to reproduce.
