What is TRUE about the invasion and metastasis of cancer cells?

Does not require modification of junction complexes between cells

Is a characteristic of benign tumors

Occurs at an early stage of carcinogenesis

Requires that cells undergo massive cytoskeletal rearrangements

Is the least serious aspect of cancer from a health perspective

Solutions

Expert Solution

ANSWER- CORRECT OPTION IS D

option 1 - incorrect, as the cell does require to undergo modifications in thejunction complexes between the cell, along with the various proteins and other enzymes which lately assist in metastasis

option 2 - incorrect, as beningn tumor are those tumors which do not spread and remains at the initial location only while the metastasis are the ones which can be spread to various location in the body, therefore option 2 is incorrect

option 3 - incorrect, as metastasis occurs at the 4th stage of cancer and is very lethal, therefore this option is wrong

option 4 - correct, as to undergo metastasis,the cell undergoes various changes in itself leading from the cytoskeleton ones to the enzymatic actions and supression of the tumor supressing genes are the ones which are included.hence, option 4 is correct

option 5 - incorrect, as metastasis is the most lethal and the most serious aspect of the cancer and it occurs on the last stage of cancer mostly. one can not take it for granted.

hence, option 4 is correct,

1. Which of the following statements is NOT true about cell size? Larger cells require more materials to survive. Material needs are tied to Volume. Maximum cell size is limited by the surface area to volume ratio When cell volume is doubled, the surface area is also doubled. As a cell increases in size, the volume increases faster than its surface area The amount of surface area of a cell determines how much material can be absorbed through the membrane...

Metastasis is responsible for about 90% of cancer associated deaths. The five year survival rate comparisons for metastatic and non-metastatic tumors in various tissues was presented in lecture 10. The prostate cancer survival rate for non-metastatic tumors is 100%, whereas for liver cancer it is 28%. Why do you think there is such a big difference in survival rates for these two cancer types when both are non-metastatic tumors? (5 points)

Which statements about the modification of chromatin structure in eukaryotes are true?

Which statements about the modification of chromatin structure in eukaryotes are true? DNA is not transcribed when chromatin is packaged tightly in a condensed form Methylation of histone tails in chromatin can promote condensation of the chromatin Acetylation of histone tails in chromatin allows access to DNA for transcription Acetylation of histone tails is a reversible process All of the above are true statements of the modification of chromatin structure in eukaryotes

What is true about the anterior pituitary gland? A. there are different types of endocrine cells found there that produce different hormones B. all hormones are released from the anterior pituitary through the hypothalamic-hypophyseal portal system C. this gland produces LH and FSH which are both amine hormones, known as gonadotropins D. the levels of most of these hormones are controlled by a positive feedback loop
