Answer:

The folding of polypeptide begin during translation of the polypeptide chain. Amino acids interact with each other to form three dimensional tertiary structure and secondary structure elements formed spontaneously as an intermediate before the formation of tertiary structure.

There are two common secondary structure elements formed that are  alpha helices(α helix) and beta pleated sheets ( β pleated sheet).  Both the structures are attcahed by a hydrogen bond which is present between amino hydrogen and carboxyl oxygen atoms in the peptide backbone.

Hence, the two common elements of secondary structure are alpha helices and beta sheets.

Gekata [30.6K]

Hi

Guam is an unincorporated territory of the United States which means that the area donot posses its own municipal government. This lies within the administrative and political jurisdiction of own area. However, they still are the citizens of United States.

The indigenous people of the Guam  Island are called Chamorros and mainly they speak English and  Chamorro languages. The people are US citizens.

Because of being an unincorporated territory , the citizens are facing several problems that should be resolved. Such as:

  • Illegal usage of drugs because there are no proper established laws.
  • Land ownership issues.
  • Unrestricted immigration in the Island because of lack of laws.
  • Domestic violence

Scientists face these issues when they want to study the life at island of Guam.

A man with cystic fibrosis of the pancreas wishes to marry a young woman whose family has never had an individual born with the
mixas84 [53]

Cystic fibrosis is a recessive condition; meaning if a dominant condition takes over it will not be seen in the offspring. The man genotype with cystic fibrosis can only be this: cc (when c is equal to the cystic fibrosis and C is equal to not having one). The woman with no history of cystic fibrosis can possibly have either of these two genotypes: Cc or CC.

To see their offspring’s possible genotype, we’ll use a punnett square let’s start with Cc:

                C             c

c              Cc           cc

c              Cc           cc            There is a 50 % chance of the child having cystic fibrosis.

To see their offsprings possible genotype with CC:

                C             C

c              Cc           Cc

c              Cc           Cc           There is no chance that the child will have cystic fibrosis.
