<h3>NEUTRONS AND PROTONS</h3>

The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.

Being color bind is an X-Linked Recessive trait. What are the genotype possibilities for a girl who is colorblind (XB or Xb )?
o-na [289]

Explanation: XX because she is female. Since she is not color blind one of the pair has to be XC. Since she is a carrier of color blindness she has to have the recessive gene as well, so the other has to be Xc.

Eukaryotic cells. Classify each statement according to whether it occurs in eukaryotic cells, prokaryotic cells, or both.
frutty [35]

Answer:

<u>Both</u>:

  • The start codon is often AUG

<u>Eukaryotic cell only:</u>

  • The larger subunit of the ribosome is 60s.
  • The ribosomes initially binds the 5' end of mRNA.

<u>Prokaryotic cell only</u>:

  • The ribosome is 70s
  • Translation occurs in the cytoplasm
  • There are multiple ribosome binding site

Explanation:

  • AUG is the common start codon for both eukaryotic as well prokaryotic cells. In eukaryotic cell, it codes for methionine . While in prokaryotic cell, it codes for formyl methionine.
  • In prokaryotic cell, ribosomes are found in cytoplasm, hence the translation occurs in cytoplasm.
  • Eukaryotic ribosome consists of two subunits; 40s and 60s(larger subunit)
  • Prokaryotic ribosomes have 70s ribososme, which consists of 50s and 20s subuints
  • in eukaryotic cell, 40s ribosome initially binds to the cap at the 5' end of mRNA.
  • Bacterial mRNA contain multiple ribosome binding sites.

Which of the processes are coupled (i.e. LINKED) in prokaryotic organisms but uncoupled (i.e. UNLINKED) in eukaryotic organisms?
PilotLPTM [1.2K]

Answer:

Transcription & translation (Ans. A)

Explanation:

Prokaryotic organisms do not have membrane-bound organelles such as the nucleus, thus the process of transcription & translation occurs in the cytoplasm. Also because of the need for rapid life cycle, the mRNA molecules start to be made, & their ribosomes are ready to start making proteins more rapidly than Eukaryote, thus the process of the couple is quicker.

In eukaryotic organisms, transcription process start (happens) inside the nucleus of the cell and translation process can't start until the mRNA is transported out from the nucleus into the cytoplasm.
