Offspring Genotypes
Offspring phenotypes?
What type of inheritance is this?
Answers
Answer:
Offspring Genotypes - ½ BO : ½ OO
Offspring phenotype - ½ Black orange cat : ½ orange cat
Type of inheritance - Co-dominance
Explanation:
This question involves a single gene coding for skin color in Siamese cat. The alleles for orange color (O) and black color (B) are co-dominant i.e. they are both expressed in a heterozygous state.
According to the question, a purebred orange siamese cat (OO) was crossed with a hybrid cat (BO). The following gametes will be produced by each parent:
OO - O only
BO - B and O
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced from this cross:
½ BO : ½ OO
½BO - Black orange phenotype
½OO - Orange phenotype
- This type of inheritance is CO-DOMINANCE

Answers
Answer:
PROTIST, FUNGI, PLANTS
Explanation:
The Protist Kingdom consists of mostly unicellular organisms that can have characteristics similar to plants, animals or fungi. Characteristics of Protists: mostly unicellular, few multicellular, eukaryotic, can be heterotrophic or autotrophic. Ex: algae, Paramecium, kelp (multicellular).
The three types of organism that would be classified as eukaryotic multicellular and heterotroic should be protist, fungi, and plants.
What is the Protist Kingdom?It should treated as the unicellular organisms that contains the attributes, similar kind of the plants, animals, or fungi.
The attribute of protists involved the unicellular, less multicellular, eukaryotic, heterotrophic or even autotrophic.
These organisms are classified together since they are made up of eukaryotic cells.
Therefore, the above should be considered as the protist, fungi, and plants.

What is the correct mRNA transcription of the following DNA sequence? ATGGCACCTTAC
A. UACCGUGGAAUG
B. AUGGCACCUUAC
C. CAUUCCACGGUA
D. CATTCCACGGTA
Answers
Why? None of the other sequences will match up correctly
The process of transcription produces the mRNA sequence from the DNA. The mRNA transcription of ATGGCACCTTAC will be UACCGUGGAAUG. Thus, option A is correct.
What is mRNA transcription?Transcription is the process of the formation of mRNA from the replicated DNA strand of the cell. It produces an mRNA transcript that is a single strand and further codes for amino acids.
The mRNA transcript forms by the base pairing with the DNA template. If the DNA sequence is ATGGCACCTTAC then according to the base pairing rule the adenine (A) pairs with uracil (U) in mRNA, and guanine (G) pairs with cytosine (C). In mRNA, the adenine binds with uracil and not thymine, and hence A pairs with U, whereas the G-C bond remains the same.
The DNA strand: ATGGCACCTTAC
The mRNA sequence will be: UACCGUGGAAUG
Therefore, option A. UACCGUGGAAUG is the mRNA transcript.
