Hello everyone here we have a question that says blank is an inherited disorder that affects the body's ability to break down the amino acid phenylalanine to tyrosine. So we have a tyrus anemia. Toros anemia is a metabolic disorder in which the body is unable to properly break down the amino acid tyrosine. And what this does is lead to the build up of tyrosine and its toxic byproducts in the body and can cause a range of symptoms that can include damage to the liver, kidneys and other organs. So A. Is incorrect. Be maple syrup urine disease in maple syrup urine disease. It affects the breakdown of certain amino acids such as losing I solution and bailing. It is characterized by an abnormal accumulation of specific amino acids and their broad products in the blood and urine. This gives the urine a sleep sweet smell like maple syrup, which gives us the name maple syrup urine disease. So B. Is incorrect. See non catalytic hyperglycemia. In non catalytic hyperglycemia, it is a metabolic disorder caused by a deficiency of an enzyme called glycerin cleavage system. And what this does is cause an accumulation of the amino acid glycerine and this can cause symptoms like low muscle tone seizures and coma. So C. Is incorrect. And lastly we have fennel ketone area, fennel clinton area is a rare disorder in which the body is able to properly break down the amino acid finality to tire scene. So d is our correct answer. Thank you for watching. Bye

What are isoaccepting tRNAs? Assuming that there are only 20 different aminoacyl tRNA synthetases but 31 different tRNAs, speculate on parameters that might be used to ensure that each charged tRNA has received the correct amino acid.

Textbook Question

Predict the amino acid sequence produced during translation by the following short hypothetical mRNA sequences (note that the second sequence was formed from the first by a deletion of only one nucleotide):

Sequence 1: 5'-AUGCCGGAUUAUAGUUGA-3'
Sequence 2: 5'-AUGCCGGAUUAAGUUGA-3'

What type of mutation gave rise to sequence 2?

Textbook Question

A short RNA molecule was isolated that demonstrated a hyperchromic shift (see Chapter 10), indicating secondary structure. Its sequence was determined to be

     5'-AGGCGCCGACUCUACU-3'

If the molecule were an internal part of a message, what amino acid sequence would result from it following translation? (Refer to the code chart in Figure 13.7.)
