How can a gene determine whether a person has albinism (give a molecular explanation.)?

Biology
1 answer:
Finger [1]4 years ago
4 0
The <em>TYR </em>gene is responsible for the production of the enzyme tyrosinase which is crucial in the production of melanin which is primarily responsible for skin pigmentation and for pigmentation of other organs. In albinism, there is mutation of the <em>TYR </em>gene therefore there will be no transcription of DNA to mRNA and no translation of mRNA to the enzyme tyrosinase leading to its deficiency. The deficiency of tyrosinase will eventually lead to the absence of melanin and ultimately, the absence of pigmentation in an organism.

synthase.

Attachment of the specific Amino acid.

Interaction with codon.

Explanation:

Transfer RNA is a type of RNA that help to translate messenger RNA sequence into protein. Each tRNA have two major areas; the anticodon and region for attaching specific Amino acids.

tRNAs function at specific sites in the ribosomes during mRNA deciding.

What organelle is missing from the red blood cells?
taurus [48]

Answer:

The correct answer is - they lack a nucleus, DNA, and organelles like the endoplasmic reticulum or mitochondria

Explanation:

Red blood cells are considered as the cells, carry oxygen with the help of hemoglobin protein present in it to the various parts of the body from the lungs and carry CO2 back to the lungs.

These cells are different from the normal cell as they do not participate in the protein synthesis due to the fact that they lack various cell organelle and cell components required. Nucleus and DNA are major components or organelle missing from these cells. In addition to these two, endoplasmic reticulum and mitochondria also missing from RBCs.
