How many dna molecules are present in your diploid cells

Biology
1 answer:
Tcecarenko [31]3 years ago
7 0

Answer:

92 molecules

Explanation:

DNA or Deoxyribosenucleic acid is polynucleotide made up of several nucleotides containing the genetic information of an organism. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA, tightly coiled many times around proteins called histones to support its stucture.

Human cells, like myself, contains 23 pairs of chromosomes (46 chromosomes in total). Each pair coming from each parent. Each chromosome is formed by two strands of DNA held together by hydrogen bonds forming the DNA double-helical structure. These two DNA strands form a base pair, which is a unit of two nucleotide bases bound to each other by hydrogen bonds. According to the complementary base pairing rule, Adenine (A) pairs with Thymine (T) while Guanine pairs with Cytosine (C).

Since there are 46 chromosomes in a diploid human cell and each chromosome consists of 2 DNA strands, then, there are 46 × 2 = 92 strands/molecules of DNA in each human diploid cell.

Is the ocean salty because the land never waves back?
timofeeve [1]
NO, the ocean is salty because it is the place where many of the salt from lakes and rivers leave off in. If this doesn't happen, then there will not be any fresh water, there will only be salty rivers, very salty rivers, not so salty rivers, or so salty to the point you can't even drink it salty water (lol)

The formal system for classifying and naming organisms was developed by The formal system for classifying and naming organisms w
bixtya [17]

Answer: Carolus Linnaeus

Explanation:

The formal system of classification was introduced by a Swiss scientist named Carolus Linnaeus.

He first split living things into a general category called KINGDOM.

- The kingdom is further split into large smaller groups called PHYLUM (for animals) and DIVISION (for plants).

- Each phylum or division is broken down into CLASSES.

- Each class is broken down into ORDERS

- Orders into FAMILIES,

- Families into GENUS

- Genus into SPECIES

Thus, the linnaean system of classification from highest (most general category) to the lowest level is as follows: Kingdom --> phylum/division --> class --> order --> family --> genus --> species.
