What is added to the polypeptide strand?
Amino Acids from the tRNA strand during the translation process.
When the wrong nucleotides are added to a strand of DNA during DNA replication they can never be repaired?
Plato .... False
What type of RNA is formed during transcription?
In Translation, rRNA, tRNA, and mRNA are used. The mRNA strand of codons (3 nucleotide bases) enters the ribosome where the rRNA will "read it" (it is made up of rRNA). tRNAs are floating in the cell carrying the anticodon's specified amino acid. When the rRNA "sees" which codon is on the mRNA strand, the tRNA's anticodon (complementary nucleotide bases) binds to the A site in the ribosome to start creating the polypeptide chain.
The continually elongating strand of new dna at one side of a replication fork during dna replication is known as?
The strand of DNA that is being continually created is known as the leading strand. The strand that is being created in sections/loops is known as the lagging strand. The reason that these two strands are created differently is because the two strands of DNA run in different directions (they are anti-parallel). This means that because new nucleotides can only be added in a 5'-3' direction, the two strands cannot be created in the same method.
How many bases does a double helix have after the complementary strand is added?
double the amount of bases (or x2)
What is added to the polypeptide strand?
Amino Acids from the tRNA strand during the translation process.
What prevents the wrong nucleotide from being added to the new strand during DNA?
DNA Polymerases
When the wrong nucleotides are added to a strand of DNA during DNA replication they can never be repaired?
Plato .... False
A nucleotide is about to be added to a growing strand of DNA. What factor determines which type of nucleotide will be added?
The nucleotide to be added is determined by the nucleotide on the DNA stand. They always come in pairs. G matches with C and A with T.
What is the step of protein synthesis that occurs in the nucleus?
The step of protein synthesis that occurs in the nucleus is transcription. Transcription is the process of copying the genetic code from DNA into RNA. The RNA molecule that is produced during transcription is called messenger RNA (mRNA). mRNA then travels to the cytoplasm, where it is translated into a protein. In transcription, the DNA double helix opens up at a specific location called the promoter. A protein called RNA polymerase binds to the promoter and begins to move along the DNA strand, unzipping the helix as it goes. RNA polymerase then uses the exposed DNA strand as a template to synthesize a complementary RNA strand. This RNA strand is the mRNA molecule. Once the mRNA molecule is complete, it separates from the DNA and travels to the cytoplasm. In the cytoplasm, the mRNA molecule binds to a ribosome. The ribosome then reads the mRNA molecule and uses the information to assemble a protein molecule. The protein molecule is then released from the ribosome and can go on to perform its function in the cell. Here are the steps of transcription in detail: Initiation: RNA polymerase binds to the promoter region of DNA. Elongation: RNA polymerase moves along the DNA strand, unzipping the helix and synthesizing a complementary RNA strand. Termination: RNA polymerase reaches a termination sequence in the DNA and stops synthesizing RNA. The mRNA molecule that is produced during transcription is a single-stranded molecule that contains the same information as the original DNA strand. However, the mRNA molecule is modified in a few ways. First, the 5' end of the mRNA molecule is capped with a group of nucleotides called a 5' cap. The 5' cap helps to protect the mRNA molecule from degradation and helps it to bind to the ribosome. Second, the 3' end of the mRNA molecule is polyadenylated, which means that it is added to a long chain of adenine nucleotides. The polyadenylation tail helps to stabilize the mRNA molecule and helps it to be transported to the cytoplasm. Transcription is a complex process that is essential for protein synthesis. It is the first step in the process of converting genetic information into a functional protein molecule.
What is the type of amino acid during transcription that is added to the growing poly potide dependson is?
codon on the mrna and the anticodon trna to which the amino acid is attached
Sequence the steps of transcription and RNA processing by dragging the labels to their correct locations in the flowchart?
a. transcription is initiated b. 5' cap is added c. introns are removed d. transcription is terminated e. 3' poly-A tail is added f. mRNA exists nucleus
How do cell become differentiated from one another when they all share the same DNA?
One strand of DNA is kept during the copy of DNA, while also a new one is added for a new strand, allowing it to become a double helix again.
What type of RNA is formed during transcription?
In Translation, rRNA, tRNA, and mRNA are used. The mRNA strand of codons (3 nucleotide bases) enters the ribosome where the rRNA will "read it" (it is made up of rRNA). tRNAs are floating in the cell carrying the anticodon's specified amino acid. When the rRNA "sees" which codon is on the mRNA strand, the tRNA's anticodon (complementary nucleotide bases) binds to the A site in the ribosome to start creating the polypeptide chain.
Why RNA primers are needed during DNA replication and what is their fate?
DNA polymerase cannot begin the synthesis of new DNA.To synthesis a new strand of DNA ,RNA primer is required.The complementary RNA nucleotides,that are added opposite to the single strand of parent DNA are the RNA primer.
The continually elongating strand of new dna at one side of a replication fork during dna replication is known as?
The strand of DNA that is being continually created is known as the leading strand. The strand that is being created in sections/loops is known as the lagging strand. The reason that these two strands are created differently is because the two strands of DNA run in different directions (they are anti-parallel). This means that because new nucleotides can only be added in a 5'-3' direction, the two strands cannot be created in the same method.
What determines which type of nucleotide will be added?
Base pairing rules
