Question

1- Why are male cats unable to express both orange and non-orange colors simultaneously in the same way as female cats?

D- make cats only have one X chromosome

2- Which statement is false?

B- chromosomes contain RNA only

Use the simulation to answer the question- what has a greater influence on protein levels?

B- polymerase affinity has a greater influence because you cannot start reading mRNA without it.

4- A normal allele for a gene has more base pairs than mutated from of the allele. Which type of mutation occurred?

A- base pair deletion

5- A DNA code or the code for certain proteins undergoes a substitution mutation. The new current codon for the same amino acid as the original Codon. What is the most likely effect of mutation.

C- The mutated codon produces the same protein as the original codon and does not cause a disease.

6- The two processes of using DNA to make MRNA and then use the mRNA to make a functional proteins are?

B- transcription and translation, respectively

7- In the cells of multicellular organisms, proteins are assembled in the?

D- ribosome

8- which type of regulation in prokaryotes targets The mature mRNA for it can be used in protein synthesis?

C- translational control

9- transcription of a gene can be blocked when which factor attaches to the operator?

D- repressor

10- A short Pea plant is crossed with a tall, HETEROZYGOUS pea plant. Use a punnets square to determine the probability of short offspring.

D- 50%

11-Traits can be affected by one gene and can be influenced by the environment. Human blood types are controlled by to Non-Mendelian patterns of inheritance. These two patterns are?

B- Codominance and multiple alleles

12-human blood has four phenotypes: A, B, AB, and O. These genes for A and B are dominant, while O is recessive. If a person has AB blood type, what inheritance pattern is demonstrated?

B- Codominance

13- A tall Pea plant is crossed with a short pea plant. Half the offspring are tall and a half or short. How would you designate the allele for tallnes?

A- T



My answers,

Answer 1

YUP UR CORRECT AS OF 1/19/22

Answer 2

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

Answer 3

thanks bro I got all of them correct. :)

Answer 4

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

Answer 5

Beni is wrong, Its still one X chromosome
