What is the final result of DNA replication of one chromosome quizlet?
What is the final result of DNA replication of one chromosome? A thymine base is replaced by a cytosine in a DNA molecule.
What is the end result of DNA replication?
The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.
How many copies of DNA are left after replication?
1 double stranded DNA (dsDNA) can form 2 double stranded DNA molecules when it is replicated. Each one of the two strands of the initial dsDNA is used as a template to form a new strand and eventually end up with a new dsDNA molecule formed from each of the two initial DNA strands.
What is the end result of replication of a duplex DNA molecule?
Hydrogen bonds break and helix opens. Each strand of DNA acts as a template for synthesis of a new, complementary strand. Replication produces two identical DNA double helices, each with one new and one old strand.
What takes place in the nucleus quizlet?
Transcription occurs in the nucleus and is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes.
What are the monomers of DNA called?
The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T).
What is the end result of translation?
When the ribosome reaches a stop codon, it releases the mRNA strand and amino acid sequence. The amino acid sequence is the final result of translation, and is known as a polypeptide. Polypeptides can then undergo folding to become functional proteins.
What would the chromosome to the right be called after DNA replication?
Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.
What do you have at the end of DNA replication how many molecules one strand or two identical to the original molecule or different ?)?
DNA replication is semi-conservative. This means that each new molecule of DNA contains one strand of the parent molecule and one complementary strand that is newly synthesized (daughter strand). Hence two newly generated molecules remain similar to the parent DNA molecule.
How many pairs of DNA is created after replication?
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.
What phase does DNA replication occur?
In the eukaryotic cell cycle, chromosome duplication occurs during “S phase” (the phase of DNA synthesis) and chromosome segregation occurs during “M phase” (the mitosis phase).
What is semi conservative in DNA?
Definition of semiconservative
: relating to or being genetic replication in which a double-stranded molecule of nucleic acid separates into two single strands each of which serves as a template for the formation of a complementary strand that together with the template forms a complete molecule.
What is the result of DNA replication quizlet?
This process produces two DNA molecules, each composed of a new and an original strand. The nucleotide sequences in both of these DNA molecules are identical to each other and to the original DNA molecule.
