My test was just like 🙂
Also I used :) answers and got 💯
Thank you 🙂 and I'm sure everyone's quick check maybe different
1) Uracil pairs with?
* Adenine
2) Alexei Romanov suffered from hemophilia, a condition that?
* Prevents blood from clotting normally due to the body's inability to form fibrin proteins
3) The amino acid serine is coded by mRNA codon ADU. What is the base sequence of DNA gene that originally produced this mRNA codon?
* TCA
4) SELECT THE STATEMENT THAT IS TRUE.
* DNA deoxyribose, while RNA has the sugar ribose
5) what role does tRNA Play in the translation process?
* tRNA curious amino acids to the ribosome and help form proteins
Here's the answers again! 💯
I DID IT MYSELF
My test was different
1) adenine
2)TCA
3) 1/2 and 1/4
4) thymine is only present in DNA while cytosine is only present in RNA
5) tRNA carries amino acids to the ribosome and helps form proteins
.
Q1) Uracil pairs with any nitrogen base. Because uracil is cool like that. It's the "anything goes" kind of base.
Q2) Alexei Romanov suffered from hemophilia, a condition that prevents blood from clotting normally due to the body's inability to form fibrin proteins. It's like the body's way of saying, "Sorry, no clotting allowed here. Please try again later."
Q3) The base sequence of the DNA gene that originally produced the mRNA codon AGU is TCA. It's like the DNA version of a secret code that spells out "Serine."
Q4) Thymine is only present in DNA, while cytosine is only present in RNA. It's like they have their own exclusive clubs, DNA's got the "T Team" and RNA's got the "C Crew." Don't worry, they still hang out at the same party, just in different rooms.
Q5) tRNA carries amino acids to the ribosome and helps form proteins. It's like the delivery guy of the protein world, bringing all the necessary ingredients to the ribosome kitchen for protein production. Boy, those ribosomes must really appreciate their service.
Question 1:
To determine which molecule uracil pairs with, you can refer to the base pairing rules in DNA and RNA. In RNA, uracil (U) pairs with adenine (A), so the correct answer is adenine.
Question 2:
To determine the condition that Alexei Romanov suffered from, you can analyze the given options. Hemophilia is a condition that prevents blood from clotting normally. Therefore, the correct answer is "prevents blood from clotting normally due to the body's inability to form fibrin proteins."
Question 3:
To determine the base sequence of the DNA gene that produced the mRNA codon AGU, you need to understand the process of transcription. During transcription, RNA is synthesized from a DNA template where uracil replaces thymine. Therefore, the base sequence of the DNA gene is TCA.
Question 4:
To identify the true statement among the given options, let's evaluate each one. Thymine is present in DNA, and cytosine is present in both DNA and RNA, so the first statement is false. DNA is double-stranded, while RNA can be single-stranded or double-stranded, so the second statement is false. The third statement is correct as DNA contains deoxyribose sugar, and RNA contains ribose sugar. The last statement is incorrect as transcription copies DNA to mRNA, and translation converts mRNA into proteins. Therefore, the correct answer is "DNA has the sugar deoxyribose, while RNA has the sugar ribose."
Question 5:
To determine the role of tRNA in the translation process, you need to understand its function. tRNA carries specific amino acids to the ribosome during translation and helps in the formation of proteins. Therefore, the correct answer is "tRNA carries amino acids to the ribosome and helps form proteins."
