The answer is D. Mitosis

Here are what happened in other option :
Cytokinesis : Dividing process of Cytoplasm

Interphase : A phase when the cell copies its DNA for the preparation of Mitosis
Meiosis : A single cell divides twice to produce 4 cells containing half the original amount of its genetic information

What you mentioned above is Mitosis

Note that the lac enzyme continues to be produced even in the absence of lactose. Why is this a problem? Try dragging the lac op
aniked [119]

Answer:

If the lac enzyme continues to be produced even in the absence of lactose, the cell will be expending energy unnecessarily and this will be a problem for the supply of energy for other metabolic processes.

If the lac operator gene is dragged to any stretch of DNA, that gene may provide an inadequate reading generating a mutation.

Explanation:

The lac operon is an essential molecule for the transport and metabolism of lactose in microorganisms. This molecule has a fundamental function in the life of these single-celled organisms and must be synthesized immediately when lactose is present in the organism, however, its synthesis must be stopped as soon as the lactose is metabolized, otherwise the cell can spend energy unnecessarily preventing others Metabolic processes take place, which is a big problem if you only have one cell.

In addition, if for some reason, the lac operon gene is dragged on the DNA strand, an incorrect reading of the DNA bases can occur, which can cause mutations.

7. What is the purpose of the replicases?
masya89 [10]

Answer:

Replicates can be used to measure variation in the experiment so that statistical tests can be applied to evaluate differences. Averaging across replicates increases the precision of gene expression measurements and allows smaller changes to be detected.

Fruit production in anthophytes develops from: a. a female reproductive structure b. a male reproductive structure c. both male
Fed [463]

Answer:

a. a female reproductive structure

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.

Division Antophyta are classified into two (2) main categories and these includes;

I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.

II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.

Basically, fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.

How are the hardy-weinberg principles used in the analysis of codis genotypes and other strp-locus comparisons?
lana66690 [7]
<span>HWE is used with COIDS and non CODIS eligible DNA profiles to provide statistical caluclations for the rarity or uniqueness of profiles. Each STR kit test for a certian number of loci. Each lous has a set ladder of observed alleles. Each of these alleles has value for its observed frequency in a population. It is the rarity of each allele at each location that will give you the value for rarity of the profile as a whole. This rarity fo the profile is calucalted in CODIS under certian circumstances using to determine the eligibilty of a partial profile or a forensic mixture to determine its eligiblity for the different leves of the database.</span>
