Answer 3

Alexei Romanov suffered from hemophilia, a condition that prevents blood from clotting normally due to the body’s inability to form fibrin proteins.

Answer 4

The amino acid serine is coded by the mRNA codon AGU. What is the base sequence of the DNA gene that originally produced this mRNA codon?(1 point) Responses TCA TCA AGU AGU UCA UCA TCC

Answer 5

The mRNA codon AGU is transcribed from the DNA sequence that would have the complementary base pairing. The base pairing rules are A (adenine) pairs with T (thymine) and U (uracil in RNA) pairs with A (adenine). Therefore, the DNA sequence that codes for the mRNA codon AGU would be:

TCA

So the correct answer is TCA.

Answer 6

Select the statement that is true.(1 point) Responses Translation copies DNA to mRNA, while transcription converts mRNA into proteins. Translation copies DNA to mRNA, while transcription converts mRNA into proteins. DNA has the sugar deoxyribose, while RNA has the sugar ribose. DNA has the sugar deoxyribose, while RNA has the sugar ribose. Thymine is only present in DNA, while cytosine is only present in RNA. Thymine is only present in DNA, while cytosine is only present in RNA. DNA and RNA are both double-stranded.

Answer 7

The true statement is: DNA has the sugar deoxyribose, while RNA has the sugar ribose.
