This gene is a mutant variant that severely slows the growth of the bacteria. The normal version of the encoded protein should contain the partial amino acid sequence (Nterm...T-R-N-A...Cterm). It's known that mutant forms of tRNA synthetases can charge tRNAs with a different amino acid than expected. If a mutant synthetase gene was introduced into the E. coli, which one could produce the normal version of the encoded protein? If a mutant synthetase gene was introduced into the E. coli, which one could produce the normal version of the encoded protein?

a. synthetase that charges an asparagine tRNA with asparagine
b. synthetase that charges a histidine tRNA with histidine
c. synthetase that charges an asparagine tRNA with histidine
d. synthetase that charges a histidine tRNA with asparagine

Pls quickly! which of the following is true about the behavior of an organism? a. the behavior of an organism is influenced by both its heredity and it’s environment. b. the behavior of an organism is influenced only by the treats it inherits from its parents. c. the behavior of an organism is influenced only by the environment in which it lives in. d. the behavior of an organism is not influenced by either it’s heredity or its environment.

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
