Students have asked these similar questions
DNA replication is called semi-conservative because ___ (all, all or none) of the two new strands of DNA is old DNA from the original DNA molecule and ___ (all, all or none) is new DNA.
When DNA replicates, each resulting DNA molecule retains half of the original DNA strand. Because of this, the process is described as
Which of the following statements is TRUE of BOTH DNA replication and DNA transcription?
During the process, the DNA double helix is separated into single-stranded regions.
An intermediate in the process is an RNA-DNA hybrid helix.
During the process, only one single-stranded DNA region acts as a template.
Amino acids are matched to a strand of DNA to form a new polymer.

- A mutation results in the presence of multiple DNA fragments on the newly synthesized DNA strand following DNA replication. Which enzyme has most likely been mutated? O DNA helicase DNA polymerase DNA ligase O DNA primasearrow_forwardDuring DNA Replication, _____________ is synthesized in a series of short pieces called _______________arrow_forwardthe human immunodeficiency virus HIV uses RNA rather than DNA to encode genetic information. During infection, however, HIV uses an enzyme known as reverse transcriptase to generate double-stranded DNA. Generally speaking, how would the enzyme generate a double strand of DNA from a single strand of RNA?arrow_forward
- You see that a piece of DNA is being copied. But you cannot tell if this an example of DNA replication or RNA transcription. Describe three ways that you can tell the two processes apart.arrow_forwardA portion of one strand of DNA has the sequence 5′ AATGGCTTA 3′. If this strand is used as a template for DNA replication, write the sequence of the newly synthesized strand in the direction from left to right in which it will be synthesized.arrow_forwardA chromosome consists of a long DNA molecule wrapped around protein clusters. The DNA you extracted still has some protein bound to it. To get pure DNA, the protein must be removed. A common way to do that is to denature the protein. What would be an easy way to do that?arrow_forward
- DNA can copy itself through a process known as _____.arrow_forwardA large number of nucleotide base pairs along a DNA molecule is a specific region called a _____arrow_forwardThe final steps of DNA synthesis involve the removal and replacement of primers with DNA, and the formation of the final phosphodiester bonds of the backbone which join all the fragments into one unbroken strand of DNA. True or false?arrow_forward
