Please explain how treadmilling contributes to actin-based motility in crawling cells. Be specific in why both actin filament growth a d shrinkage are necessary.

Answers

The actin filaments in cell constantly grow and shrink. This occurs through addition or removal of subunits. The two ends of actin filament have different dynamics of addition and removal of subunits. That way, one end of actin filament will grow and one end will shrink so it seems like the filament is moving. This phenomenon, known as treadmilling is characteristic for both actin filaments and microtubules.

Which of the following pairs of genotypes result in the same phenotype? A. IAIA and IAIB
B. IBIB and IBi
C. IBIB and IAIB
D. IBi and ii

Answers

IB IB and IB i is the pair of genotypes that results in the same phenotype.
genotypes means the genetic constitution of an individual organism.And phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Hence,
The right answer is :
B. IBIB and IBi

Final answer:

Option B, IBIB and IBi, result in the same phenotype of Type B blood.

Explanation:

The correct answer is B. IBIB and IBi.

The phenotypes of the ABO blood group in humans are determined by the presence or absence of antigens on the surface of red blood cells. There are three alleles for this gene: IA, IB, and i.

In option B, both genotypes have the genotype IB, which means they both have the B antigen and will result in the same phenotype of Type B blood.

In the typical cell cycle, DNA synthesis occurs in the _________ phase.

Answers

Deoxyribonucleic acid (DNA) synthesis refers to the creation of a new DNA molecule, which occurs in the cell cycle’s synthesis phase (S phase). Duplication of the centrosome, which organizes microtubules to help insure proper chromosomal segregation during cellular division, as well as DNA replication occur during this phase and are necessary for the stimulation of cellular division. {Synthesis phase}

Limiting contact between gamma rays and healthy tissue is important because?

Answers

Gamma ray is high-frequency electromagnetic radiation. It is known that gamma rays are able to damage DNA molecules in the cells by interrupting DNA strands. That characteristic of gamma rays is used in the treatment of tumors. An idea was that gamma rays will damage DNA molecules of tumor cells and, consequently, prevent uncontrollably divisions of tumor cells. But, in treatments, it is very important to limit contact between gamma rays and healthy tissue. This way it will be minimized damage of DNA molecules in healthy cells.

Answer: gamma rays are high energy and may cause damage to healthy cells.
