What’s the mRNA sequence?
What will be the amino acid sequence?
Will there likely be effects?
What kind of mutation is this?

Answers

Answer 1
Answer:

mRNA Sequence: AUGUGGAACCGUGACU

Amino Acid Sequence: Methionine-Tryptophan-Asparagine-Arginine-Cysteine.

Likely Effects: Minimal impact, as the mutation is a silent mutation, not changing the amino acid.

Mutation Type: Point Mutation.

To find the mRNA sequence, we need to perform transcription, where DNA is used as a template to synthesize complementary mRNA. In this case, we have a substitution mutation in the DNA sequence, so the mRNA sequence will also be affected.

Original DNA Sequence: T A C A C C T T G G C G A C G A C T

Mutated DNA Sequence #5: T A C A C C T T G G G A C G A C T

The mRNA sequence is formed by replacing T with U (uracil) in the DNA sequence:

Original mRNA Sequence: A U G U G G A A C C G C U G C U G A

Now, let's determine the amino acid sequence using the mRNA sequence. Amino acids are coded by codons (three-letter sequences). Here's the mRNA sequence grouped into codons:

AUG UGG AAC CGC UGC UGA

The codons code for specific amino acids:

AUG: Methionine (start codon)

UGG: Tryptophan

AAC: Asparagine

CGC: Arginine

UGC: Cysteine

UGA: Stop codon

So, the amino acid sequence is Methionine-Tryptophan-Asparagine-Arginine-Cysteine.

As for potential effects, the mutation seems to result in a single amino acid change (from glycine to asparagine). Whether this has significant effects on the protein's function depends on its role. If the protein is critical for an essential function, even a single amino acid change can have noticeable effects. However, if it's a less crucial protein or a non-coding region, the impact may be minimal.

This mutation is a point mutation, specifically a missense mutation, where one nucleotide is substituted with another, leading to an amino acid change in the resulting protein.

Answers

A protein channel is a transport protein that helps larger molecules, that would otherwise not be able to diffuse through the membrane of a cell to move in or out of the cell depending on the concentration gradient.

A _____ is a horizontal stem that can divide and grow in several directions at once. corm rhizome stolon bulb

Answers

The correct answer is rhizome.

Rhizome is a modified horizontal underground stem. Rhizome may or may not be fleshy. It becomes fleshly when it stores food as in ginger. It looks like root but it is not root because there is presence of nodes, internodes, scale like leaves on it and it is frequently develops branches in different direction. Through rhizome many plants propagates vegetatively.    

Answer:

A rhizome is a horizontal stem that can divide and grow in several directions at once.

Use specific examples from Joseph Priestley’s experiment to explain the relationship between what he observed and what he inferred.

Answers

Answer:

Priestly observed that adding a plant to the jar caused the candle to stay lit longer.

Priestly himself inferred that plants gave off oxygen during photosynthesis, it provided the oxygen that was needed for the candle to be able to burn.

Answer:

Joseph Priestly observed that a candle alone in a jar did not stay lit for long and eventually went out and that when he added a plant to the jar, it caused the candle to stay lit longer and the plant to stay alive longer. Priestly then inferred that plants give off oxygen during photosynthesis, providing the oxygen needed for the candle to burn and that the burning candle gave off carbon dioxide, which was used by the plant.

Sensing the position and movement of individual body parts is an example of which sense? (a)-Kinesthetic
(b)-Vestibular
(c)-Auditory
(d)-Umami Olfactory

Answers

Answer:

(a)-Kinesthetic

Explanation:

  • The Vestibular sense is responsible for our sense of spatial orientation or balance.
  • The Auditory sense is responsible for the perception of sounds.
  • The Umami Olfactory sense is responsible for our sense of smell and taste.

So the answer is (a), kinesthesic. It is thanks to the kinesthetic sense that we can go up stairs easily without stopping to see and carefully control the movement of each of our legs.
