The Correct Answer and Explanation is :
Here are the correct answers for the multiple-choice questions, along with a detailed explanation:
- RNA can leave the nucleus.
- mRNA is made during transcription.
- mRNA is made in the nucleus.
- DNA is located in the nucleus.
- Transcription converts DNA into mRNA.
- mRNA is used to carry the genetic code from DNA to the ribosomes.
- rRNA makes up the ribosome.
- RNA uses uracil instead of thymine.
- Amino acids make up a protein.
- Transcription takes place in the nucleus.
- tRNA is used in translation.
- tRNA uses anticodons to match to the mRNA.
- Proteins are made at the ribosome.
- mRNA attaches the amino acids into a chain.
- tRNA is found in the cytoplasm.
- Translation converts mRNA into a protein.
- Translation takes place in the cytoplasm.
Explanation:
- RNA can leave the nucleus because, unlike DNA, RNA is synthesized in the nucleus and then transported out to the cytoplasm where translation occurs. DNA, on the other hand, remains in the nucleus as the blueprint for RNA synthesis.
- Transcription is the process where the DNA sequence is used to create a complementary mRNA strand. This mRNA strand carries the genetic information to the ribosomes for protein synthesis.
- The nucleus is where mRNA is made. This is because DNA is found in the nucleus, and transcription happens there, producing mRNA. After transcription, mRNA leaves the nucleus to be translated into protein in the cytoplasm.
- DNA is found in the nucleus of a cell where it holds the genetic information.
- Transcription is the first step in gene expression, converting DNA into mRNA, which is a copy of the genetic code that can be translated into proteins.
- mRNA carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs.
- rRNA makes up the ribosomes, which are the sites of protein synthesis.
- RNA uses uracil (U) instead of thymine (T), which is found in DNA. This is one of the key differences between RNA and DNA.
- Amino acids are the building blocks of proteins. Proteins are chains of amino acids that fold into specific structures, enabling them to perform various functions in the cell.
- Translation occurs in the cytoplasm at the ribosomes. During translation, mRNA is read by the ribosome to assemble amino acids into a polypeptide chain (protein).
- tRNA helps decode the mRNA by carrying amino acids to the ribosome, where they are linked together to form proteins.
- Codons are three-nucleotide sequences on the mRNA that specify which amino acid is added to the growing protein chain. Anticodons are complementary to codons and are found on the tRNA.
- The process of translation in the cytoplasm is where mRNA is decoded into a specific protein.
This process from DNA to mRNA to protein is known as central dogma in molecular biology. The diagram you mentioned illustrates how DNA is transcribed into mRNA, which is then translated into a sequence of amino acids that form proteins.
