In STR profiling, PCR is used to obtain enough DNA to then detect the number of STRs at I specific loci.

Licemer1 [7]

PCR technique is important in STR profiling in order to amplify and detect the number of Stars at a specific gene loci.

<h3>What is Short Tandem Repeat (STR) profiling?</h3>

Short Tandem Repeat profiling is a technique in molecular biology used to compare allele repeats known as STRs at specific loci in DNA between two or more samples.

The PCR (polymerase chain reaction) technique used in STR profiling involves making multiple copies is a particular segment of DNA in order to make enough quantities detectable in the analysis.

Therefore, PCR technique is important in STR profiling to detect the number of Stars at a specific gene loci.

What could a scientist do to determine what era the Eocene Period belongs to on the geologic time scale?

Burka [1]

Answer:

Option B) study information related to the Cenozoic era

Explanation:

The complete question is

Scientists discovered that the Eocene time period existed in Earths history around 34 MYA. What do they need to do to determine what time period Eocene belongs to on the geologic time scale?

A) learn what happened during Precambrian time

B) study information related to the Cenozoic era

C) view the timing of events in the Mesozoic era

D) research events that happened during the Paleozoic era

Solution -

The period of Eocene belong to the Cenozoic era. The Cenozoic era is divided into three periods-

a) The Paleogene – Existed between 65.5 to 23.03 million years ago

b) The Neogene - Existed between 23.03 to 2.6 million years ago

c) The Quaternary – Started some 2.6 million years ago and is continuing till present

The Paleogene is subdivided into three epochs –

A) The Paleocene – existed between 65.5 to 55.8 million years ago

B) The Eocene – existed between 55.8 to 33.9 million years ago and

C) The Oligocene – existed between 33.9 to 23.03 million years ago

Hence, studying about Cenozoic era will give information about the Eocene epoch

Hence, option B is correct

A standard PCR cycle includes three steps: denaturation (95Â°C), annealing (55Â°C), and elongation (65Â°C).

xz_007 [3.2K]

Answer:

Denaturation process: The DNA template

Annealing process: Primers

Elongation process: dNTPs and Taq polymerase

Explanation:

For the denaturing process, the only ingredient that is required is the DNA template that will be separated from a double helix (or double strand) into a single strand, by increasing the temperature to 95 C, (at this temperature the hydrogen bonds that keep together the double stranded break). After the double strand is denatured, the following process is annealing. For this, the required ingredient are the primers; these primers will hybridize or anneal according to the nucleotide complementarity to the single strand of the DNA. Finally, for the Elongation process, you will require the Taq polymerase and the dNTPs. The enzyme will synthesize or “generate” a new strand of DNA based on the DNA template, using the provided dNTPs in the direction 5’ to 3’.

I hope this clarify you inquiry.
