Actin filaments have polarity. This means that the two ends can be identified due to structural differences. The plus end is the

end to which subunits are added more rapidly. True or False
Biology

Naily [24]3 years ago

Answer:

True

Explanation:

Actin is a globular protein which can polymerize to form long filaments called actin filaments. These filaments are abundant in muscle cells but are also found in other places.

While polymerizing, the new actin monomers always join the existing filament in the same orientation hence the filament becomes polar. It has a barbed end and a pointed end. Barbed end is also called plus end because monomers are added to this end five to ten times faster than the minus or pointed end. As a result, the filament overall grows in the plus end direction. Hence, the given information about actin filament is true.

In the family tree below, people with the recessive trait of attached earlobes
madam [21]

Answer:

C. It is a male with atleast one dominant allele

Explanation:

In the given pedigree, the two normal parents of the generation I have one daughter with the attached earlobe. Since the trait is recessive, the daughter should be homozygous recessive to express the trait. The genotype of the daughter (shaded circle in generation II) is "aa". To have a daughter with "aa" genotype, both the parents should have one copy of "a" allele. So, the genotype of both parents is "Aa".

In generation II, individual A is non-shaded square. Squares represent males in a pedigree. Since its not shaded, it does not have attached earlobe. Both the parents are heterozygous dominant for attached earlobes (Aa x Aa = 1/4 AA : 1/2 Aa : 1/4 aa). The genotype of this individual may be AA or Aa.
