vova2212 [387]
Last night Jasmine and Jay amount combined is $150+$130=$280
amount donated to charity is 1/4 of $280= $70
amount spent at an amusement park is` 40/100 x $210= $84
the remaining money = 280- (70+84)= $126

35% of their original amount is 35/100x$280=$98

so Jay's claim is not correct because the remaining money is $126 and not $98 as she Jay claims.

Morgarella [4.7K]

Answer:

This statement is true

Explanation:

The genetic code is required for the production of proteins with exception of some few mitochondrial proteins. The transfer RNA (tRNA) acts as an adaptor that enables to associate a messenger RNA trinucleotide sequence (known as anticodon) with its corresponding amino acid in the polypeptididic chain. The genetic code is considered to be a biochemical system capable of revealing the information contained in the DNA in order to synthetize a protein, which has been encrypted in the form of three nucleotides (i.e., codons).

Regulatory and basal transcription factors regulate transcription by binding to the promoter.A) True B) False
Licemer1 [7]

Answer:

False

Explanation:

In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.

There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.  

Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.
