Aleks04 [339]3 years ago
7 0

Answer: During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. Chromosomes are made of a single piece of DNA that is highly organized.

They usually have the fear that their feelings won’t b respected and tend to behave in a way by considering the feelings of other people while ignoring their own.

Lack of eye contact,  poor body gesture etc are the signs of passive communication. The lack of ability to communicate outward often results in passive communicator’s getting misunderstood.

How does the nucleotide sequence determine the protein structure and function of a cell?
Montano1993 [528]

Answer:

The four bases A, T, C and G make up the genetic code. The base sequence determines amino acid sequence in protein. Messenger RNA (mRNA) is a molecule which carries a copy of the code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.

Tay–Sachs disease is an autosomal recessive disorder. Homozygous recessive individuals lack a key enzyme called hexosaminidase A
myrzilka [38]

Answer:

0.033

Explanation:

Tay–Sachs disease is an autosomal recessive disorder. The possible genotypes and phenotypes are:

  • TT = normal
  • Tt = carrier
  • tt = Tay-Sachs disease

I will use <em>p </em>to call the frequency of the dominant <em>T</em> allele, and <em>q</em> the frequency of the recessive <em>t</em> allele.

If the population is in equilibrium, the frequency of the tt genotype is q².

q^2 = 1/3600\\\\q=\sqrt{1/3600} \\\\q=1/60=0.017\\\\and\\p + q = 1\\p=1-q\\p=0.983

The frequency of the Tt genotype is 2pq.

2pq= 2*0.983*0.017\\2pq=0.033

The Tay–Sachs carrier frequency will be 0.033
