Select the true statemente
select the statement that is true translation copies, DNA to mRNA while transcription converts mRNA into proteins
DNA has a sugar deoxyribose. Wow RNA has sugar ribose
DNA has a sugar deoxyribose while running has the sugar ribose
DNA and RNA are both double-stranded
thymine is only present in DNA while cystone is only present in rna
The true statement is: "DNA has a sugar deoxyribose, while RNA has sugar ribose."
To select the true statement, we need to analyze each statement and determine its accuracy:
1. "Translation copies DNA to mRNA, while transcription converts mRNA into proteins."
This statement is incorrect. The process of transcription involves copying the DNA sequence into mRNA, and translation is the process where mRNA is used to synthesize proteins. Therefore, this is not the correct statement.
2. "DNA has a sugar deoxyribose, while RNA has sugar ribose."
This statement is true. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. Therefore, this is the correct statement.
3. "DNA has a sugar deoxyribose while running has the sugar ribose."
This statement seems to be incorrectly worded. It does not make sense to associate the sugar ribose with "running." Therefore, this is not the correct statement.
4. "DNA and RNA are both double-stranded."
This statement is incorrect. DNA is typically double-stranded, consisting of two complementary strands held together by hydrogen bonds. However, RNA is typically single-stranded. Therefore, this is not the correct statement.
5. "Thymine is only present in DNA, while cytosine is only present in RNA."
This statement is incorrect. Thymine is indeed present only in DNA, but cytosine is present in both DNA and RNA. Therefore, this is not the correct statement.
Based on the analysis, the correct statement is:
- "DNA has a sugar deoxyribose, while RNA has sugar ribose."
The true statement is:
"DNA has a sugar deoxyribose while RNA has sugar ribose."
