Color blindness is a X-linked recessive trait. A couple want to predict whether it would be possible for their child to be color blind. The female is an unaffected carrier and the male is red/green color blind. What percentage of offspring would be color blind?
Answers
Answer: There is a probability (n.b. NOT certainty) that half of all offspring will be colour blind.
Explanation: The female is XX and as an unaffected carrier we can assign genotype Cc where c is the recessive allele.
The male is XY and colour blind, so genotype cY
Male offspring can be cY or CY so p|colourblind = 50%
Female offspring can be Cc or cc so, again p= 50%
If there is also equal probability of sex of the offspring, there is an overall probability that half the offspring will be colour blind

Molecules of DNA are composed of long chains of?
Answers
two long polynucleotide chains
A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together
Molecules of DNA are composed of long chains of nucleotides.
What are nucleotides?Nucleotides are the building blocks of DNA and RNA adenine (A), thymine (T), guanosine (G), and Cytosine (C. In RNA, uracil (U) is present instead of thymine.
The pentose sugar is the ribose sugar in RNA and deoxyribose sugar in DNA. In deoxyribose sugar, oxygen is absent from the 3' carbon.
Phosphate groups are attached through the 5-C of pentose sugar by an ester bond. One polynucleotide chain is formed when the phosphate of one nucleotide forms a phosphodiester bond with the sugar of another nucleotide.
A double-stranded structure is formed by base pairing between nucleotides. The adenine binds to thymine by two hydrogen bonds and guanine binds to cytosine by three hydrogen bonds.
Therefore the molecules of DNA are composed of long chains of nucleotides.

DNA strands run in 1 of 2 directions depending on which end of the strand is free and which end has a phosphate bond. One direction is 5' to 3' (__________) and the other direction is 3' to 5' (downstream). __________ polymerase binds to the DNA at the TATA box and unzips the double helix. Working along the DNA chain, RNA polymerase reads the DNA nitrogenous bases and matches RNA nitrogenous bases from the nucleus (uracil instead of thymine). As it moves, RNA polymerase re-zips the DNA behind it and lets the mRNA separate from the DNA. It continues to do this until it reaches a sequence downstream called a __________ signal. In other words, RNA polymerase copies the DNA sequence downstream of the TATA box into an mRNA strand.

The answers in the blank spaces:
1. Upstream
2. RNA
3. Terminator
Explanation:
This question is describing the process of transcription, which is the process whereby DNA template is used to synthesize an mRNA molecule. Transcription involves three stages viz: initiation, elongation and termination.
- DNA strands run in 1 of 2 directions depending on which end of the strand is free and which end has a phosphate bond. One direction is 5' to 3' (UPSTREAM) and the other direction is 3' to 5' (downstream). An enzyme called RNA polymerase binds to the DNA at the TATA box and unzips the double helix (INITIATION).
- Working along the DNA chain, RNA polymerase reads the DNA nitrogenous bases and matches RNA nitrogenous bases from the nucleus (uracil instead of thymine). As it moves, RNA polymerase re-zips the DNA behind it and lets the mRNA separate from the DNA (ELONGATION).
- It continues to do this until it reaches a sequence downstream called a TERMINATOR signal (TERMINATION). In other words, RNA polymerase copies the DNA sequence downstream of the TATA box into an mRNA strand.
According to the data in the table, what percent of the elodea cells is water? Explain how you arrived at this conclusion.
Answers
Answer:
99%
Explanation:
at a salt solution concentration of 2%, plasmolysis first started to occur. So the other 98% in the "solution" would have just been water. Since water inside cells needs to be greater than the amount of water outside the cells, we can say that the amount of water inside the elodea cells was 99% so that it can allow hypertonic plasmolysis to occur.

Explanation:
Meiosis makes genetic variety possible. It makes sperm & egg cells called gametes. Each gamete has 23 chromosomes. To make a diploid cell two gametes (sperm & cell) come together.
During prophase 1 the chromosomes pair up with their homologous pairs so they can transfer their genetic information and exchange it between each other. It makes recombinant chromosomes that influence the genetic diversity between the same people.
Now they are in metaphase 1, the chromosomes are in pairs in the middle of the cell. In anaphase 1, the chromosomes are pulled away by the spindle fibers. Then in telophase 1, there are two formed nuclei. Cytokinesis 1 then splits the cytoplasm.
Now they are in meiosis 2. During prophase 2, there are chromosomes and the spindles are starting to form again without crossing over like in prophase 1. In metaphase 2, chromosomes are going to line up in the middle in both cells unlike during metaphase 1 where the chromosomes were only in pairs. In anaphase 2, only the chromatids are being pulled away by the spindle fibers. Next in telophase 2 the nuclei reform and the 2 cells are each going to divide into 4 cells. Finally, cytokinesis completely splits the cytoplasm.
Keeping in mind that each sex only produces one type of gamete cell (sperm or eggs), and of the independent assortment and crossing over of chromosomes, the end result will be diversity.
