DNA replication is said to be semiconservative. Which of the following statements correctly explains what this means?

Answers

Answer: DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands.

This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.

Explanation: https://youtu.be/Gxoyr8JKc4w

Hope this helps :D

The semi-conservative nature of DNA replication illustrates that each strand in the DNA double helix function as a template for the synthesis of a new or complementary strand.

What is DNA replication?

DNA replication may be defined as a type of biological process that deals with the synthesis of two identical replicas of DNA from one original DNA molecule during cell division.

The semi-conservative model of DNA was proposed by Watson and Crick. This model implies that each double helix of DNA is composed of one new and one old strand.

In semi-conservative replication, the parental double helix is half conserved and each parental single strand remains intact.

Therefore, DNA replication is said to be semi-conservative due to the process of each new double strand consisting of one parental strand and one new daughter strand.

Why is genetic variation among individuals beneficial?(1 point)

A) More genetic variation means higher rate of survival versus species that have less genetic variation.

B) Genetic variation staves off extinction because it creates a fit population.

C) Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.

D) Genetic variation leads to more new traits in the population which means evolution can occur faster.

Answers

Answer:

Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.

Explanation:

it was the correct answer from the test

Genetic variations may lead to the diversity in the phenotypes of surviving individuals. It reduces the chances of extinction.

What do you mean by Genetic variations?

Genetic variations may be defined as the presence of differences in sequences of genes between individual organisms of a species.

Genetic variation among individuals is beneficial because some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.

Therefore, it is discussed above that genetic variation among individuals is beneficial.

Explanation:

To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study.

This is evidence for the existence of ___________.

Answers

Answer:

Central pattern generators

Explanation:

A central pattern generator (CPG) is a neuronal circuit consisting of neurons localized in the spinal cord capable of producing rhythmic outputs. CPGs are able to produce rhythmic movements even when the spinal cord is separated from the brain and sensory organs. CPGs are the main components of motor functions including, among others, breathing, flying, chewing, walking, swimming, etc. These neural circuits have been discovered in almost all vertebrates studied to date.

As mentioned in the video, Dr. Nachman and his colleagues have collected dark and light colored mice from dark and light colored rocks in other areas of the American Southwest and found similar patterns (i.e., dark colored mice were more likely to be found on dark rocks; light colored mice were more likely to be found on light rocks). However, genetic analysis showed that the dark fur color in other rock pocket mouse populations was caused by mutations in different genes. This means that there is more than one way (genetically speaking) to make a mouse dark. It also means that adaptive mouse coloration has occurred more than once in similar environments across the southwestern US. How does this information support the concept that natural selection is not a random process

Answers

Complete question:

In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.

How does this study support the concept that natural selection is not random?

Answer:

The study supports the concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.  

Explanation:

All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. They can do it by having a similar fur color that the color of the rocks they live on. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.
