DNA
It can contain the purine adenine
This contains the pyrimidine thymine
The sugars are connected with a 3'-5' phosphodiester link.
It contains equal amounts of guanine and cytosine. The percentage of A-T ,C-G are the same in DNA,,they are linked by hydrogen bonds.But varies in RNA.
Explanation:
.RNA
It can contain the purine adenine.
It can contain the pyrimidine uracil
This contains the sugar ribose. This is a 5C sugar with one oxygen atom deficient.The forms the lever for holding the bases and phosphate group
The sugars are connected with a 3'-5' phosphodiester link.This is the backbone of both DNA and RNA.It is formed between the sugars and the phosphate groups in both DNA and RNA.
None is made of base composition, the %T = %G. This is wrong because purines must pair with pyrimidine,but not two purines or pyrimidine pairing as shown,
Bases are attached to sugars in an alpha N-glycosides linkage.This is wrong the beta N-glycisidic bonds are the linkages

the absence of the sry gene will result in: a) external genitalia of a female; internal genitalia of a male b) A phenotypic female c) and intersex individual d) A phenotypic male e) external genitalia of a male; internal genitalia of a female
Answer:
The correct answer is option b.
Explanation:
Sex determining Region of the Y chromosome gene or sry gene is a important gene found on the Y chromosome which is responsible for testis development or so the male characteristic. An XX individual with the SRY gene of the Y chromosome, will develop as male.
Hence, Absence of SRY gene will not result in phenotypic male So,option d is not correct. intersex have male characteristic so option c is not correct.
Absence of SRY gene will lead to development of phenotypic female due to form ovary and Fallopian tube in absence of this gene
Hence, option B is correct

Explanation: the genotype is the same
Cross between same pea plants for many generations having genotype PpAa x PpAa because after crossing over parents character having a large number of phenotype in offspring, hence a is the correct option.
What is a genotype?The term "genotype" ranges to an organism's genetic makeup, in other words, it describes an organism's whole gene. The term can also be used to refer to the alleles, or variant forms of a gene, that an organism carries in a more specific meaning.
When crossing of particular traits having genotype PpAa x PpAa because after crossing over parents' character having a large number of phenotypes in offspring.
The genotype of a person is their own DNA sequence. More specifically, the two alleles a person inherited for a particular gene are referred to using this term.
Therefore genotype parents PpAa x PpAa offspring have a large number of traits the same as parents and a low number of new traits.

Another has medium brown feathers with light wings. The last one has medium brown feathers with very dark wings. natural selection reproductive maturity genetic variation genetic drift Mark this and return
Answer:
genetic variation
Explanation:
Genetic variation refers to the difference in genetic content of organisms within a population. The genetic makeup of living organisms are made up of GENES, which exists in contrasting pairs called ALLELES. Each allele is responsible for variation in traits exhibited by the organisms. Differences in the allelic content of organisms of the same species leading to the display of varying phenotypic characteristics is referred to as GENETIC VARIATION.
This is the case in the example given in which four birds in a population possess a range of wing and feather colors i.e light brown feathers with darker wings, dark feathers with lighter wings, medium brown feathers with light wings, and medium brown feathers with very dark wings, all resulting from a variation in their genetic content. Hence, this is an example of GENETIC VARIATION.

A graduate student studying biology at the University of Nebraska has identified a new species of spider found only in Eastern Nebraska around Omaha. The graduate student determines that the spider has six homologous pairs of chromosomes. How many chromosomes would a cell in that spider have during metaphase of mitosis?
Answer:
12 chromosomes
Explanation:
Mitosis is a type of cell division that involves the formation of two genetically identical daughter cells. The two daughter cells are genetically identical in the sense that they contain the same number of chromosomes as the parent cell. Mitosis involves four stages namely: Prophase, Metaphase, Anaphase and Telophase.
In the metaphase stage as stated in this question, homologous chromosomes align at the equator of the cell called cell plate, before each chromatids are pulled apart by microtubules at the Anaphase stage.
According to the question, the spider being worked on has 6 pairs of chromosomes, which will align at the cell's equator during metaphase stage of mitosis. Since the replicated chromosomes (chromatids) are yet to separate to opposite poles of the cell, the cell will still contain 12 chromosomes at the metaphase stage.
N.B: Each chromosome contains 2 chromatids or replicated chromosome, which will be separated at the Anaphase stage. Each chromatid will be an individual chromosome after cytokinesis.
The precursor of EGP is translated from a transcript that has had one non templated nucleotide added to the open reading frame. This change does not create or eliminate a stop codon. Compared with the protein sGP, which is produced from the unedited transcript, EGP most likely has the same primary:
Answer:
Explanation:
It was added somewhere in the middle. Since this is a frameshift, everything downwind of the addition will most likely be different.
The question is basically asking, if you change everything from the middle to the end of an amino acid sequence, which end changes and which end would remain the same?
It basically asks, when amino acids are assembled into proteins, are they built from the amino to the acid direction, or the acid to the amino direction?
The answer is that amino acid sequences are always assembled N to C, much like nucleotide sequences are built 5 to 3.

how much water was retained by soil C
Answer:
we dont know sorry but i dont know
Al wonders if adding salt to water will affect how long it takes the water to freeze. Al thinks that salt water will freeze more quickly than fresh water. He decides to check his hypothesis by conducting an experiment. Al takes two ice trays and fills one with distilled water and the other with distilled water that has two tablespoons of salt added. He makes sure he puts exactly the same amount of water in each ice tray. Al takes the trays and puts them side by side in the freezer. Al checks the ice trays every 10 minutes to see if the water in each tray has begun to freeze. Al finds that after 20 minutes the water in the ice tray without the salt has started to form ice, while the ice tray with the salt water is still completely liquid.
What is his hypothesis?
a. Salt water freezes slower than fresh water.
b. Water freezes in a freezer
c. Salt water freezes faster than fresh water.
d. water will freeze in 20 minutes
salt water freezes slower than fresh water

What is nucleotide base pairing?There are five types of nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases. Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purines.
DNA consists of adenine, cytosine, guanine, and thymidine. In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil.
Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.
Therefore, these four bases are basic units of DNA.
