My answers,

YUP UR CORRECT AS OF 1/19/22

It lets you check your answers on the Practice. I also suggest you peeps keep this as a study guide for the test. <3

thanks bro I got all of them correct. :)

Beni is wrong, Its still one X chromosome

1- Male cats are unable to express both orange and non-orange colors simultaneously because they are just not as fashion-forward as their female counterparts. They're more focused on catching mice and taking naps than worrying about their coat color coordination.

2- The false statement is B- chromosomes contain RNA only. Actually, chromosomes contain both DNA and RNA, like a genetic power couple.

3- The simulation shows that polymerase affinity has a greater influence on protein levels because it's like that friend who always convinces you to go out and have a good time, while the other factors are more like the party poopers who just want to stay in and watch Netflix.

4- A base pair deletion occurred in the mutated form of the allele. It's like accidentally deleting a word in a sentence and changing its meaning. Whoops!

5- The most likely effect of the substitution mutation is that the mutated codon still produces the same protein as the original codon and doesn't cause a disease. It's like a spelling mistake in a joke - it might change the appearance a bit, but the punchline is still funny.

6- The two processes of using DNA to make mRNA and then using the mRNA to make functional proteins are transcription and translation, respectively. It's like a two-step dance routine: first, you write down the moves, and then you actually perform them.

7- Proteins are assembled in the ribosome, which is like a protein factory. It's where all the ingredients come together to create the final product - a beautiful protein masterpiece.

8- Translational control targets the mature mRNA so that it can be used in protein synthesis. It's like a bouncer at a club, making sure only the cool proteins get in and have a good time.

9- Transcription of a gene can be blocked when the repressor attaches to the operator. It's like a traffic cop directing the flow of gene expression - sometimes they stop the cars (transcription), sometimes they let them through.

10- The probability of short offspring in a cross between a short and a heterozygous tall pea plant is 50%. It's like flipping a coin - you have an equal chance of getting heads or tails, or in this case, short or tall offspring.

11- The two non-Mendelian patterns of inheritance for human blood types are codominance and multiple alleles. It's like a fashion show where more than one designer's clothes are on display, and they all influence the final look.

12- If a person has AB blood type, it demonstrates a codominance inheritance pattern. It's like having a wardrobe full of clothes from both parents and rocking a unique style that's all your own.

13- The allele for tallness would be designated as T. It's like giving someone a nickname based on their height - in this case, T for tall.

1- Male cats are unable to express both orange and non-orange colors simultaneously in the same way as female cats because they have only one X chromosome. The gene for coat color in cats, known as the orange/non-orange gene, is located on the X chromosome. In female cats, who have two X chromosomes, they can have a mix of orange and non-orange colors because they can have different versions of the gene on each X chromosome. However, male cats, who have only one X chromosome, can only have one version of the gene, either orange or non-orange, resulting in a single coat color.

2- The false statement is B- chromosomes contain RNA only. Chromosomes contain DNA, which carries the genetic information of an organism. RNA is a different type of nucleic acid that is involved in protein synthesis and other cellular processes.

To answer the question of which has a greater influence on protein levels using the simulation, we need to consider the role of polymerase affinity. Polymerase is an enzyme involved in the transcription of DNA into RNA. If polymerase has a high affinity or a strong binding ability to a specific DNA sequence, it will be able to efficiently transcribe that DNA into RNA, leading to higher protein levels. Thus, polymerase affinity has a greater influence on protein levels because without it, mRNA cannot be properly synthesized and translated into proteins.

4- A base pair deletion mutation occurred. A normal allele for a gene has a specific sequence of base pairs. In a deletion mutation, one or more base pairs are lost or deleted from the gene's sequence, resulting in a shorter allele with fewer base pairs.

5- The most likely effect of a substitution mutation in the DNA code is that the mutated codon produces the same protein as the original codon and does not cause a disease. In a substitution mutation, one nucleotide is replaced with another in the DNA sequence. However, the genetic code is redundant, meaning that multiple codons can code for the same amino acid. Therefore, if the mutated codon still codes for the same amino acid as the original codon, there will be no significant change in the resulting protein.

6- The two processes of using DNA to make mRNA and then using mRNA to make functional proteins are transcription and translation, respectively. Transcription is the process where RNA polymerase binds to a DNA template strand and synthesizes a complementary mRNA strand. Translation is the process where the mRNA is used as a template to assemble amino acids into a protein according to the genetic code.

And so on for the remaining questions.

all are correct as of 2022 except for the first question

1. is "male cats have a dominant Y chromosome"
thanks for the answers tho id rather get 15/16 over 0/16 lol
